Experienced and professional animal trainer provide their insights in answering this question :
A. Puppies try and eat everything so often have tummy bugs. It could be that it has just licked or eaten something that hasn’t agreed with it. Definitely initially rule out worms, so treat with a good quality worm treatment from your vet if you haven’t done so already. It can also be associated with a change in diet. If your puppy has vomited more than a few times, is vomiting water or blood or passing bloody diarrhoea or is very lethargic then you should have it examined by your vet as soon as possible as little animals can become dehydrated and go downhill very quickly.

How to Identify Common Pet Problems ?

However, here are some signs that you`ll want to bring them to the vet sooner rather than later: Multiple occurrences of vomiting or diarrhea. Vomiting for more than 12 hours or diarrhea that goes on for more than 24 hours. Noticeable loss of energy, lethargy, or an inability to stand and walk.
Stress, a sudden change in diet, a viral infection, or intestinal parasites can all cause these bacteria to overgrow. Bacterial infections that may cause vomiting and diarrhea include: Salmonella. Campylobacter.
Small bouts of watery diarrhea or a small amount of regurgitated food can often be treated at home by feeding a bland diet little and often, withholding all rich treats and titbits. Tepid water can be offered but should not be gulped. Puppies with vomiting and diarrhea should still appear bright and normal at home.
Salmonella, E. coli, Clostridium, and other bacteria can cause puppy diarrhea. These diseases are serious and are usually accompanied by other symptoms, like bloody diarrhea, loss of appetite, fever, and vomiting.
Some of the signs of parvovirus include lethargy; loss of appetite; abdominal pain and bloating; fever or low body temperature (hypothermia); vomiting; and severe, often bloody, diarrhea. Persistent vomiting and diarrhea can cause rapid dehydration, and damage to the intestines and immune system can cause septic shock.
A: The reasons why your puppy has diarrhea could include a change in diet, eating something unusual, exposure to toxins, viral or bacterial infections, food allergies or intolerances, intestinal parasites, stress, and other potentially serious health problems.
When signs of parvo start showing, the stool gets more watery, becoming brownish to black diarrhea with traces of blood. After signs of parvo start to show and diarrhea gets bloody and smelly, it`s a race against time because most dog fatalities happen within 2 to 3 days after the symptoms.
Teething can also make puppies sick, causing a decrease in appetite, upset stomach, or unusual stools. However, these symptoms shouldn`t be long-lived; if your puppy is displaying these symptoms for a prolonged period of time, act accordingly. You should consult your veterinarian if you have any concerns.
If your puppy has diarrhea but is still playful and normal, there is no need to panic. It will likely resolve on its own. Here are the signs to call your veterinarian to schedule an appointment: Diarrhea that lasts more than a day.
If your dog has diarrhea but is acting fine and isn`t displaying any other symptoms, the issue is contained in the GI. This means it`s more than likely that your dog ate something that isn`t agreeing with them or has a parasite infection.
The scent generally associated with parvo is caused by blood in the stool. Dogs with bloody stools because of hookworms have precisely the same smell. MORE IMPORTANTLY, if a puppy is diagnosed with Parvo BEFORE there is blood in the stool, the antivirals` effectiveness is MUCH GREATER.
Although vaccination is effective at preventing Parvo, even vaccinated dogs may occasionally be infected by Parvovirus and develop disease. The vaccine provides immunity against the virus, but it is not 100% effective.
Symptoms of Parvo

Your dog will not drink water nor eat, and very soon the pup will be stretched out and down on the ground, unable to get back up. They will become limp, weak, and unable to hold themselves up. Parvovirus, when left untreated, is often fatal. It requires veterinary oversight.

Keep an eye on your canine companion`s bowel movements and see if things clear up. If your dog has more than 2 episodes then there might be a problem, so it`s a good idea to call your vet if your pup has two or more bouts of diarrhea.
Loose stools can mean your dog`s food isn`t being absorbed in his GI tract, which could point to a food allergy or intolerance, says Huggins. Diarrhea can also indicate that your dog has a serious infection (like a parasite, a bacterial infection, or inflammatory bowel disease).
Several days after the appearance of early symptoms, a distinctive bright red rash may appear on your child`s face — usually on both cheeks. Eventually it may spread to the arms, trunk, thighs and buttocks, where the rash has a pink, lacy, slightly raised appearance.
Intestinal parasites: Intestinal parasites such as roundworms, hookworms, whipworms, coccidia, and giardia can cause gastrointestinal symptoms that can mimic the parvovirus.
Dogs that develop parvo will show symptoms three to 10 days after being exposed. Symptoms include: vomiting, lethargy, diarrhea (usually bloody) and fever. The gastrointestinal tract is where the heaviest damage occurs.
Tests to diagnose parvovirus infection in a dog include fecal viral antigen testing and polymerase chain reaction (PCR). Fecal antigen testing is an effective diagnostic tool and is most commonly performed in the clinic.
In the U.S., people tend to get infected with parvovirus B19 more often in late winter, spring, and early summer. Mini-outbreaks of parvovirus B19 infection occur about every 3 to 4 years. Since parvovirus B19 only infects humans, a person cannot get the virus from a dog or cat.
1) Overfeeding – Many owners are unaware that overfeeding can cause loose stools. This is due to an `overload` of the digestive system, meaning it is unable to absorb what it needs and instead expelling it. This is more common in young puppies with sensitive stomachs but can happen at any age.
Puppies have sensitive stomachs, and even subtle changes to their diets can result in unpleasant side effects like diarrhea. This is often a temporary nuisance, but it`s all the more reason to work closely with your veterinarian to devise a feeding plan.
Recovery time usually is within a few days but sometimes can last a week or more. If left untreated, gastroenteritis can worsen and cause severe dehydration which can be life-threatening.
Most cases of acute gastroenteritis improve rapidly after rehydration. Call your veterinarian if the vomiting and diarrhea do not improve significantly within 48 hours of treatment. Gastroenteritis is a common condition seen in veterinary practice.

Q. How do I determine how much my overweight pet should weigh?
ANSWER : A. There are many tools to determine overweight and obesity levels in pets. A new tool, morphometric measurements and body fat index, are available to accurately determine a pet’s ideal weight; this will allow an accurate determination of the amount of food a pet should receive to achieve weight loss. Feeding the correct amount will lead to greater weight loss success.

There are many weight loss food options to help pets reach their ideal weight. Your veterinarian can help make a ideal weight recommendation. Here are some tips to help your dog lose weight in a healthy and safe way:

1. Diet: Providing a healthy and well balanced diet is essential to your pet’s overall health. Finding the right food for your dog can be a challenging process. For those overweight animals many commercial dog companies offer weight loss diets, but it is important to evaluate food labels for adequate nutritional content.

You want to ensure you are not missing other essential vitamin or mineral content. Volume of food is also important and the amount of food that works for one breed of dog may not be the same for another breed of dog. Portion control as opposed to free-choice feeding can help your dog to drop a few unnecessary pounds.

There are also prescription weight loss foods designed by veterinary nutritionists, such as Hill’s r/d (http://bit.ly/1AoENSd). Some pet owners find that home cooking is the best option for helping to provide a well-balanced and realistic diet plan. There are websites such as balanceit.com that offers recipes to fit your dog’s specific needs. Consulting with your veterinarian or a veterinary nutritionist to find the appropriate diet is a great way to help your dog be as healthy as possible.

2. Exercise: Another great tactic for weight loss for your dog is exercise. Whether this is through running, walking or playing with a favorite toy all of these are wonderful types of exercise to help keep your dog at a lean and healthy weight.

For those pet owners with busy schedules utilizing professional dog walking services or playtime through dog daycare services is another option. It has been shown that those pet owners that exercise regularly with their pets generally live a healthier lifestyle.

3. Physical therapy: As animals age pet owners offer encounter their favorite canine having more difficulty walking and have a dwindling desire to play with toys. Physical therapy, specifically hydrotherapy is a wonderful way to help older and arthritic animals gain more mobility and lose weight. Hydrotherapy has been proven to have several therapeutic effects on the body including, muscle strengthening, relief of swelling, decreased joint pain, less stiffness in limbs, improved circulation, weight loss, and increased tissue healing to name a few. For more information on the benefits of hydrotherapy:

4. Veterinary visit and blood work: Weight gain can also be related to underlying health concerns such as hypothyroidism or other endocrine disorders. Scheduling a veterinary evaluation and routine blood work can be another important component in increasing the longevity of your dog’s life. Conditions such as hypothyroidism that predispose dogs to gain weight can be treated with a daily medication to improve hormonal balance. If feel that your dog is unnecessarily overweight there can be an underlying health condition that needs to be addressed.

5. Healthy treats: Pet owners love the chance to reward their favorite canine companion with treats and most dogs jump at the chance to consume these delicious products. The problem is many treats, which can include commercial dog treats or table scrapes can add many unnecessary calories to your dog’s daily intake. Reading labels and making note of the calories in these treats is an important component of understanding your dog’s overall health. Treats should not exceed more than 10 percent of your pet’s daily calories. There are healthier treats that can be offered to your pet to keep calories lower yet provide a fuller sensation. A pet owner can add steamed or pureed vegetables, such as carrots, green beans or sweet potato to add more fiber and thus a fuller feeling for your dog.

Q. Whenever I take my dog on walks he always barks at people and others dogs in my neighborhood. What should I do to resolve the problem
ANSWER : A. The very first thing to do is to make sure your dog is getting sufficient physical and mental exercise every day. A tired dog is a good, happy dog and one who is less likely to bark from boredom or frustration. Depending on his breed, age, and health, your dog may require several long walks as well as a good game of chasing the ball and playing with some interactive toys.

Figure out what he gets out of barking and remove it. Don’t give your dog the opportunity to continue the barking behavior.

Ignore your dog’s barking for as long as it takes him to stop. That means don’t give him attention at all while he’s barking. Your attention only rewards him for being noisy. Don’t talk to, don’t touch, or even look at him. When he finally quiets, even to take a breath, reward him with a treat. To be successful with this method, you must wait as long as it takes for him to stop barking. Yelling at him is the equivalent of barking with him.

Get your dog accustomed to whatever causes him to bark. Start with whatever makes him bark at a distance. It must be far enough away that he doesn’t bark when he sees it. Feed him lots of good treats. Move the stimulus a little closer (perhaps as little as a few inches or a few feet to start) and feed treats. If the stimulus moves out of sight, stop giving your dog treats. You want your dog to learn that the appearance of the stimulus leads to good things.

Teach your dog the ‘quiet’ command. Oddly, the first step is to teach your dog to bark on command. Give your dog the command to “speak,” wait for him to bark two or three times, and then stick a tasty treat in front of his nose. When he stops barking to sniff the treat, praise him and give him the treat. Repeat until he starts barking as soon as you say “speak.” Once your dog can reliably bark on command, teach him the “quiet” command. In a calm environment with no distractions, tell him to “speak.” When he starts barking, say “quiet” and stick a treat in front of his nose. Praise him for being quiet and give him the treat.

As in all training, always end training on a good note, even if it is just for obeying something very simple, like the ‘sit’ command. If you dog regresses in training, go back to the last thing he did successfully and reinforce that before moving on again. Keep sessions short, 15-20 minutes max, and do this several times a day.

Q. Why does my dog eat grass?
ANSWER : A. As another user mentioned, dogs can eat grass when they want to vomit. Sometimes, when a dog has an upset tummy, they will eat grass. If you notice your dog eating grass frantically, you can assume vomiting will shortly follow. Grass does not digest and pass normally. If your dog eats too much grass, it can cause serious issues with pooping. Your dogs poop can end up all tangled inside of her, and it can need veterinary assistance to remove it. The same goes for celery, so avoid feeding celery to your dog.

The other day my boyfriend accidentally left the laundry room door open where we were keeping the trash that was filled with cooked chicken bones. She ate one of the chicken bones lightning fast. We had to induce vomiting by feeding her some hydrogen peroxide. After we had fed her the peroxide, she immediately began frantically eating grass because her tummy was upset.

If there is something lacking in your dogs diet, it could be that your dog is eating grass to make up for it. I am sure that my dogs diet is extremely well balanced (I do not only feed her an air-dried raw food-type diet (Ziwipeak), but a wide variety of safe, healthy foods), so when she eats grass, I know that it is because she has an upset tummy.

That is why I think it is important making sure your dog has a very well balanced diet. If your dog is on a low quality kibble, your dog may be trying to let you know by eating grass (or eating poop).

Q. Which common foods are poisonous to pets?
ANSWER : A. That’s a great question. As responsible pet owners we need to be aware of food items that can be harmful to our canine or feline companions. Here are some of the most common foods proven to cause illness in our animals at home:

Chocolate: A favorite and irresistible treat amongst most humans, chocolate is considered toxic to dogs. In very small amounts it is usually not a huge issue, but with larger volumes and with darker chocolates pet owners should be concerned. Chocolate contains methylxanthine theobromine, which is similar to caffeine. Chocolate ingestion can cause vomiting, diarrhea, hyperactivity, issues with normal heartbeats, seizures, and in some severe cases, death. It is best to keep your favorite chocolate treats in a good hiding spot and out of reach of your dog or cat.

Grapes and raisins: Dogs should not consume grapes and raisins because of the risk of acute kidney failure. Most dogs experiencing grape or raisin toxicity will begin to have vomiting and/or diarrhea within 6-12 hours of ingestion. Other abnormal clinical signs include lethargy, abdominal pain, dehydration, and tremors. Kidney failure develops within 24-72 hours of the initial ingestion. There are some dogs that do not experience these devastating side effects. It is best to contact your veterinarian or veterinary emergency facility if you believe your pet has ingested grapes or raisins.

Garlic and onions: We often forget that our meals contain these two popular ingredients and will allow our furry companions a few bites or licks. Onion and garlic both can cause a type of poisoning that results in damage to red blood cells, making them more likely to rupture. They can also cause stomach upset and mouth irritation. Look for pale gums, increased breathing or drooling or any vomiting or diarrhea.

Bread dough: Unbaked bread dough is considered poisonous to our pets. The bread dough, when ingested, expands in the stomach because of the warm and moist environment. This can lead to a bloated or even twisted stomach. In addition yeast is often added to our baking products to help get bread to rise, and when this yeast is fermented it produces both carbon dioxide and alcohol. The alcohol produced can be absorbed into the bloodstream and causes dangerous drops in blood sugar, blood pressure and body temperature. Common clinical signs include vomiting or retching, distension of the stomach, weakness and collapse.

Macadamia nuts: Ingestion of these nuts are not proven to be fatal in dogs but can cause them to experience uncomfortable clinical sings, including fever, joint stiffness, vomiting, tremors and difficulty walking, especially in their hind legs. Often your pet will start to feel better after about 48 hours, but supportive veterinary care (such as pain medication) may help ease their discomfort.

Xylitol: The most common ingredient used in sugar-free gum is xylitol, which is a non-caloric sweetener. It is also found in some oral rinses, toothpastes and vitamins. Xylitol and dogs do not mix – it can cause a dangerous drop in blood sugars levels. Dogs will often display signs of disorientation, black tarry stool, tremors and seizures. If severe enough some dogs have developed liver failure. Keep your gum away from your canine companion.

Avocados: Avocados are not actually poisonous to dogs or cats but as many veterinarians can tell you the avocado pits can cause a foreign body obstruction. Avocados contain persin, which is actually toxic to the majority of pet birds. The abnormal clinical signs associated with avocado ingestion in birds include, respiratory distress, inability to perch, liver and kidney failure and sudden death.

Go forth and enjoy your favorite foods, but keep in mind which foods you should avoid sharing with your furry family members. Whenever in doubt, contact your veterinarian for healthy and safe food suggestions.

Q. My 9 month old Maltese-Shih eats his own feces. Is there anything i can give him to get him to stop?
ANSWER : A. Coprophagia (or eating stool) is very common in young dogs. Luckily, most dogs will outgrow this behavior as they age. There are several theories as to why dogs do this which range from mimicking the mother dog’s behavior of cleaning the den, nutrient deficiency, boredom or just plain enjoyment of it.

If your dog is eating his own, removing the feces as soon as he deposits them is best in preventing them from being eaten. Keeping your dog on a leash while he potties can also help to catch any stool before he finds it. If he is eating other stool as well, sweeping the area prior to letting him out to go potty can help you identify and remove any left-behind stool.

There is also a product called For-bid that is available to make stool distasteful to pets. This product is sprinkled over every meal for a period of a week. When your dog attempts to eat the stool formed from this product, it becomes distasteful and discourages him from doing so. Most dogs will stop after a week of use, but some may need a few reminders from time to time to completely stop the behavior.

Q. Rescued a dog almost two weeks ago, and now that her kennel cough is gone her personality shines!! No previous training, how should I start?
ANSWER : A. POST FOUR:

After your dog is familiar with the behavior you lured from scratch, and taught to your dog, you can start to use the “no-reward marker” I talked about. What you do is ask the dog to perform the behavior, and if the dog does not perform the behavior, you simply say your no-reward marker (choose one: eh-eh, hey, uh-oh, oops) show them the treat, put it behind your back, and BRIEFLY ignore your dog. Just turn your back for a second or two, before turning back to your dog and saying, “let’s try that again.” When you’re ready to start over with your dog, make sure you move around. If you are repeating the same cue while in the same position, while your dog is in the same position, you are likely to receive the same results. The more you move around, and start fresh, the better your chances are of having your dog listen to your cue the second time around. BIG rewards when they dog it successfully! Lots of praise and treats.

My no-reward marker is “hey.” When my dog does something wrong I say, “hey” and she immediately understands that she needs to offer a different behavior. This is clear to her. I don’t have to say it in a mean way, I simply say, “hey” in a normal tone of voice and she understands what the word means.

Once you’ve built up that connection and communication with your new dog, you can work on all kinds of fun behaviors! I personally enjoy the more zen-like behaviors: https://www.youtube.com/watch?v=ruy9UMcuGh8

I like to teach my dog fun tricks that offer her a “job” to do of sorts like object retrieval: https://www.youtube.com/watch?v=I4iertZSva8

(object retrieval training completed; what it looks like: https://www.youtube.com/watch?v=jx0Dml28FGY)

Scent-games are fun too! Very confidence building. Hide a REALLY smelly treat in a box, and place that box in a line of boxes. Let your dog go in the room while saying something like “search!” or “find it!” and watch them hunt for that smelly treat! Lots of rewards when they find it!

Q. Healthy German Shepherd has extremely loose stools once a day. I added 2 spoonfuls of pumpkin puree that hasn’t helped. No diet changes. Any advice?
ANSWER : A. Loose stools can be caused by a number of factors, and the first step is always to bring a stool sample to your local veterinarian to check for anything. Fecal exams can check for common bacteria and parasites in the stool that may cause chronic diarrhea.

Diet problems can also play a factor in loose stool as well as chronic illness. Dogs can be allergic to many different ingredients in the diet, however grains such as corn, wheat and soy products can be the most problematic. Adding a probiotic supplement can sometimes help such as a scoop of plain yogurt ever meal, or commercial product from your vet.

Illnesses and metabolic disorders may also cause chronic loose stools. German Shepherds are prone to a disease called Exocrine Pancreatic Insufficiency which is a problem with the pancreas (the same organ that dysfunctions in diabetes- however that is ENDOCRINE function in that case) producing enough digestive enzymes. This causes stools that may be loose, discolored grey or yellow and appear very fatty in color. Shepherds can also be prone to chronic small intestine infections that cause loose stool as well. Luckily, treatment for these conditions often just involves adding a daily digestive enzyme supplement to the food, or daily anti-biotic designed specifically for chronic bowel issues.

Q. How can I train my 4 month old puppy to sit?
ANSWER : A. Training basic commands such as sit is very easy using a positive reinforcement method and does not require any more materials than a place to sit and some very yummy treats! When beginning to teach your dog new tricks, starting off in a distraction free area (such as a quiet room in the house) is best. The training can then expand to more distracting places once your dog has the hang of things.

Start by showing your dog a tasty treat and placing it over his or her nose. When they begin to sniff at the treat, gently move the treat backward. Most dogs will follow the treat with their head, and the backward motion will cause their back ends to sit down! Once your dog sits, reward with the treat and some praise. If your dog tends to walk backwards instead of sit, doing this technique against a wall will prevent your dog from walking backward and encourage sitting.

Once your dog has done this a few times, begin to add the word “sit” every time you put the treat above your dog’s head. Only say the word once, and then continue with the luring motion. Your dog will begin to associate the word with the action after several tries! After this, you can begin to attempt to offer the word “sit” once, and if your dog does so, reward with a treat and praise! If your dog forgets, or appears bored, stop training and try again at a later time- most puppies only have an attention span of a few minutes at most!
