How to Identify Common Pet Problems ?

It can take up to four days to fully clear the toxins from your dog`s system. After receiving appropriate treatment, most dogs do well and recover with no long term problems. Keeping chocolate containing items out of reach of pets is the key to preventing toxicity.
Dark Chocolate: Use a scale of 1.5 ounces per 10 pounds of body weight. That`s 3 ounces for a 20 pound dog. If they`ve ingested that much or more, it`s time to call your vet. Milk Chocolate or Semi-sweet: A poisonous amount would be anything over 3.5 ounces- a standard size Hershey`s bar- for a small 10 pound dog.
As a general rule of thumb, the toxic dose of theobromine for dogs is around 100-150mg of of theobromine per kg of body weight. This equates to 20gms/kg of semi-sweet dark chocolate or 60gms/kg of milk chocolate.
Clinical signs depend on the amount and type of chocolate ingested. For many dogs, the most common clinical signs are vomiting, diarrhea, increased thirst, panting or restlessness, excessive urination, and racing heart rate. In severe cases, symptoms can include muscle tremors, seizures, and heart failure.
While dogs reach peak serum (the non-cell part of blood) levels of caffeine after 30-60 minutes and eliminate half of an ingested dose in 4.5 hours, they don`t reach peak serum levels of theobromine until after 10 hours and take 17.5 hours to eliminate half of it.
If your pet consumed the chocolate less than two hours ago, your veterinarian may induce vomiting and give them several doses of activated charcoal, which works to move the toxins out of the body without being absorbed into the bloodstream.
Affected dogs show signs 30 minutes to 4 hours after ingesting the poison. Initially affected dogs become anxious and have an elevated body temperature. Panting is usually seen. Progressively they become worse and staggery.
approximately 20 grams of semi-sweet chocolate per kg body weight. approximately 7 grams per kg body weight for baker`s chocolate per kg body weight.
The high level of theobromine in dark chocolate means it takes only a very small amount to poison a dog. Less than 25g of dark chocolate may be enough to poison a 20kg dog, that`s only a couple of squares of your bar.
After your dog eats chocolate: steps to take at home

Vetted Pet Care suggests taking only three percent solution of Hydrogen Peroxide (not the concentrated six percent solution) and putting 1ml for every pound of body weight (so 16 ml for 16 pounds), into food or in a dropper to feed her to induce vomiting.

The standard dose is 1 to 5g per kilogram of body weight depending on the amount of chocolate eaten. It`s best if you can start this within an hour of eating the chocolate. The APCC suggests sprinkling some on food, yogurt or baby food …
The darker and more bitter the chocolate, the more dangerous it is to dogs. Baking chocolate and gourmet dark chocolate are highly concentrated and contain 130-450 mg of theobromine per ounce. Common milk chocolate only contains about 44-58 mg/ounce.
Cheese can be given as an occasional treat in moderation, alongside a healthy diet. If your dog manages to eat a whole block or other large amount of cheese, they may vomit. Keep an eye on them, and call your vet for advice if they become unwell.
First aid for chocolate poisoning:

There is no antidote to Theobromine. In most cases of chocolate poisoning, your vet will initially make your dog vomit, wash out their stomach and then feed them activated charcoal to absorb any Theobromine left in the intestine.

For dogs, raw and whole meals are good options. Organic meals, natural vegetarian sources, and even biodynamic foods are perfect! Foods like beetroots, carrots and even shredded coconut would work towards detoxifying your dog`s gut! This food can clean out your dog`s digestive system and prevent indigestion.
Although chocolate toxicity may not always prove fatal to dogs or cats, it can be very dangerous and may cause lasting health problems as well.
There is no antidote for chocolate poisoning. Affected dogs are offered supportive treatment from the veterinarian to prevent further absorption of the poison and hasten elimination, along with symptomatic treatment. If the animal has just been observed eating chocolate, the veterinarian may choose to induce vomiting.
The lethal dose of theobromine is reported to be 100-500 mg/kg of body weight in dogs.
As a rule, try fasting your dog for 24 hours when they start vomiting—offer water, but no food. If they continue to vomit during that period of time, they need to have a veterinary exam. If the dog doesn`t vomit in those 24 hours, but then begins to vomit again after the 24-hour fast, they need to see a veterinarian.
Once in the hospital, your veterinarian may give your dog intravenous fluid, flush your dog`s stomach, give your dog activated charcoal to absorb the toxin, or perform surgery. Supportive medications may help your dog`s kidneys and liver process the poison and heal.
Signs & Symptoms of Poisoning in Dogs

Agitation. Tremors. Convulsions. Nausea and/or vomiting.

Go To Your Veterinarian Right Away

They will determine what is in their stomach and how to deal with it. If you can`t reach your local vet, take your dog to the nearest emergency animal clinic. In more severe cases, your vet or animal care professional may have to remove the object with an endoscopy.

Threat to pets

For milk chocolate, any ingestion of more than 0.5 ounces per pound of body weight may put dogs at risk for chocolate poisoning. Ingestions of more than 0.13 ounces per pound of dark or semi-sweet chocolate may cause poisoning.

For milk chocolate, eating more than half an ounce per pound of body weight may put your dog at risk for chocolate poisoning. For dark or semi-sweet chocolate, eating more than 0.13 ounces per pound of body weight may cause chocolate poisoning in dogs.

the most relevant questions and answers related to your specific issue

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.

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. 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 2 dogs 5lb. And 20lb. With 2 other dogs 9lb. And 27lb. Consumed about 2 oz of dark chocolate. The vets are closed what do we do?
ANSWER : A. if it is within an hour you could try making them sick, and giving them milk to drink. to coat the stomach. it’s likely that they haven’t consumed enough to be a problem. But other than making them sick you should see your vet as soon as possible if they get any symptoms.

Q. Why do dogs eat grass?
ANSWER : A. Some pet parents get concerned when they see their favorite canine nibbling on grass in the yard. They wonder whether it is because hunger, boredom or an indication of an underlying illness. Often the consumption of grass will result in vomiting because it irritates the stomach and gastrointestinal tract. This is an extremely common problem for dog parents. There is no one reason for why dogs exhibit these behaviors and it is very much dependent on each dog. Here are some of the reasons why our dogs choose to eat grass:

1. Nutritional Issues

Historically speaking, dogs are considered omnivores, which mean they consume a variety of both meat and plant-based food. There is some indication that dogs with a low fiber diet may choose to scavenge in the grass to fulfill this nutritional deficiency. These dogs may also find that grass has an appealing flavor and consistency. If you feel that this may be the reason for your beloved canine consuming grass then consider discussing with your veterinarian on how to incorporate more fiber into your dog’s diet.

2. Boredom

Many dogs who are not receiving adequate exercise will be become bored and search out activities to occupy their time, including eating grass. Evaluate how much exercise your dog is getting on a daily basis and consider more walks or other fun activities, such as playing fetch or tug of war.

3. Upset Stomach

There is a belief that dogs with an upset or gassy stomach will self-medicate by consuming grass. Vomiting often follows this grass eating activity eliminating the contents of the stomach or changing the gas distension within the gastrointestinal tract. However, there is not much scientific evidence to back up this theory. If you are concerned about too much gastric acid in your dog’s stomach or any other underlying medical issue that could be the reason for their grass eating, consult with your veterinarian.

Overall, grass eating is usually not toxic to your dogs unless your lawn contains chemicals, including pesticides or herbicides. Monitor your dog’s behavior along with his diet and exercise to determine if there is a reason for the inappropriate grass snacking.

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. 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. Is chocolate bad for my dog?
ANSWER : A. Yes chocolate is toxic to dogs. The higher the cocoa content the more toxic it is. Therefore, less amount of 80% dark chocolate needs to be consumed compared to white chocolate before toxic signs can be appreciated.

Also, the weight of the dog is important in terms of the amounts needed to be ingested before toxic symptoms appear. Less than 1oz of milk chocolate per 1lb of bodyweight needs to be eaten to be potentially lethal and less than 0.1oz per 1lb of baking chocolate is needed to be potentially fatal. If you are unsure, you should always contact your vet or emergency vet straight after ingestion.

If your dog has eaten more than the toxic amount, vomiting needs to be induced within two hours of ingestion. Clinical signs usually occur within 6-12 hours post ingestion. Mild signs can include increased thirst, restlessness, vomiting and diarrhea. More severe signs can include hyperactivity, increased urination, muscle tremors, unbalanced/uncoordinated, seizures, increased heart rate, increased breathing, coma and death.

Q. My dog keep hacking like a cough or something in her throat, what can I do?
ANSWER : A. Hacking and coughing can be caused by a number of things ranging from foreign bodies such as twigs stuck in the mouth or throat, to infections or illnesses such as Bordetella or Kennel cough, common in dogs that frequent kennels, dog daycare or dog parks. In older dogs, heart and lung issues can also be indicated by a cough that does not go away.

If you think there may be a foreign object stuck in your dog’s throat, you can sweep a finger gently through the back of the mouth or throat if your dog will let you. If something feels stuck and is not easily moved by the finger, it is best to contact your vet to have the object safely removed. This usually requires sedation so that your dog does not become panicked or move, causing the object to become further stuck or cut the throat.

If your dog is showing other symptoms of illness in addition to the cough such as runny nose or eyes, fever, lethargy or changes in appetite, it may indicate a viral or bacterial illness such as kennel cough. These are usually treated with a cough medication in severe cases, plus rest and treatment of any additional symptoms until the condition improves. In bacterial causes, antibiotics may also be given to help your dog feel better.

If your dog has a constant cough that does not go away, or has had changes in ability to exercise, breathing, or appears to have swelling around the chest or abdomen, in may indicate a lung or heart issue. Your vet can thoroughly examine your dog for any signs of heart or lung problems and can then offer care as needed depending on the cause.
