How to Identify Common Pet Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced pet care professionals :

Dogs pick up intestinal parasites by ingesting the parasite or its eggs in contaminated food or water or after licking surfaces or objects that have been contaminated with feces from an infected animal. They will then spread the parasite to other dogs in their own feces.
Several types of parasites can cause your dog to lose weight quickly. Any parasites that affect your dog`s intestines or digestive system may cause him to lose his appetite, or they may remove any nutrients your dog gets from the food he eats. When this happens, his weight loss will be noticeable.
Be aware of signs of pain, discomfort, and distress in your dog. These signs are often dramatic and can be a clear indicator that euthanasia should be considered: Labored breathing: Difficulty catching their breath; short, shallow breaths; or wide and deep breaths that appear to be labored. Lack of appetite, lethargy.
Can roundworms and hookworms infect people? Yes. These worms, like other infections that humans can get from animals, are called zoonotic (zoe-o-NOT-ick) infections or zoonoses (zoe-o-NO-sees). By learning about these infections and how to prevent them, you can help protect your pets, yourself, and your family.
NO! People may believe because worms are usually harmless in humans, that they`re probably not too dangerous in dogs either and that they can rid themselves of them, but this is not the case. Dogs cannot get rid of worms themselves. Medical assistance will be required to some extent.
Are these infections serious for dogs? Intestinal worms can be a serious problem in young puppies. Hookworms can cause anemia and roundworms can lead to poor growth and development. In adult dogs, however, intestinal parasites are only occasionally life-threatening.
Fortunately, most of it doesn`t make us sick, but some can. Parasites like hookworm, roundworm, and giardia can be passed from dog to human through licking. Salmonella, too, can be passed from your dog to you, or vice versa.
Change in Feeding Habits

A sudden change in a dog`s appetite may mean he is infected with roundworms. Food may lose its appeal, or he may suddenly be more hungry because worms are stealing nutrients from his food.

In extreme cases of tapeworm infection, your dog may lose weight despite eating normally. This is due to the tapeworm feeding on the nutrients in your dog`s intestines.
Extreme fatigue: Your normally active dog or cat may seem depressed and take no interest in exercise or play. It`s also common for a pet with cancer to sleep several more hours per day than usual.
Untreated, the average survival time from diagnosis is about two months.
“Pain is a rather substantial sign of cancer,” says Zaidel. If your dog whines or cries out when you pat her tummy or pick him up, call your vet. Mouth tumors may cause noticeable discomfort when eating.
FAQs. Can I get worms from my dog sleeping in my bed? Many worms that infest dogs are zoonotic, meaning they can cause disease in people, but people are usually infested by contact with eggs or juvenile worms in the environment rather than direct contact with the dog.
From stool or the environment

Many intestinal worms spread their eggs via their host`s stool. So, if your dog is interested in the poop of other dogs, cats, and wild animals, they could get infected that way. Plus, wherever dogs or other animals go to the bathroom, worm eggs can be left behind in the soil.

Flea tapeworm segments look like grains of rice, while roundworms look like spaghetti. Your dog may have worms and pass only tiny worm eggs which are too small to be seen, so don`t rely on seeing worms in your dog`s faeces as an indicator of worms.
Often they can go unnoticed, with few symptoms. But many times these infections cause serious illnesses, including seizures, blindness, heart failure, and even death.
The parasite can live in the intestines for many weeks or even months before symptoms are noticed. The best prevention strategy is to avoid getting your dog wet and to keep your dog away from areas where animals are commonly found.
As the dog or cat walks by, the eggs are picked up on the animal`s fur. During normal grooming, the animal then ingests the eggs. After reaching the stomach, the eggs hatch. The developing larvae continue to mature in the small intestines and become adults in about three to four weeks.
Fecal Samples Tell All

The most effective way of diagnosing parasites in dogs and cats is through fecal samples. This is why we ask that you bring a fresh stool sample with you when you come to your vet appointment.

According to WebMD, intestinal parasites like hookworm, roundworm and giardia can be passed from dog to human through licking and kissing, as can ringworm, a fungal skin infection. Salmonella bacteria which causes food poisoning, can also be passed from your dog to you, and vice versa.
To be safe, you should not kiss dogs on their heads. Most dogs, at best, tolerate humans kissing them.
Pork tapeworm or pork worm, found in contaminated meat from pigs. Dog tapeworm (hydatid worm) or roundworms, both may be on fresh produce that has not been adequately washed that was contaminated by dog feces, or, dog tapeworm may also be in contaminated meats of intermediate host animals such as sheep, beef, or pork.
Dogs need roughage in their diets and grass is a good source of fiber. A lack of roughage affects the dog`s ability to digest food and pass stool, so grass may actually help their bodily functions run more smoothly.
Signs of heartworm disease may include a mild persistent cough, reluctance to exercise, fatigue after moderate activity, decreased appetite, and weight loss. As heartworm disease progresses, pets may develop heart failure and the appearance of a swollen belly due to excess fluid in the abdomen.

the most relevant questions and answers related to your specific issue

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. My 20 month Cavalier doesn’t eat unless I let him eat from my finger, then he eats. Sometimes he will only eat once a day and leave his food.
ANSWER : A. It is possible that your dog is just not satisfied with his current food, or may be a picky eater. There are several things you can try to encourage your dog to eat.

The first step is to remove any additional treats or people food that may be more enticing to your dog than his own meal. If you feel you must give him some form of treat, be sure to place them directly in his food bowl and mixed with his regular diet. This allows him to get some snacks while also “forcing” him to try out his current meal to get the reward.

Enticing your dog to try his food by adding a pet-safe gravy or even a few treats of plain boiled chicken mixed in can help. Be sure to mix the foods thoroughly so he must explore his own food before getting the treat.

Some small breed dogs may also have a hard time with certain bowls and their collars. If there is a metal name tag on the collar and a metal bowl, the clinking sound can sometimes scare off dogs and make them not want to eat from their bowl. Using a bowl of a different material, or removing the collar prior to a meal may help with this issue.

Your dog may also just not be into his current food and may like another variety better. You can try a new variety by gradually switching over a period of 7-9 days, slowly adding in more new food and removing old until it is switched. This change may encourage him to try out meals again, and the slow changeover will allow his body to adjust to the new diet without digestive upset.

Q. My cocker spaniel is 9 years old. He has involuntary bowel movements (little drops) very frequently, especially when he is asleep.
ANSWER : A. Is your dog on a senior dog food? I would get your dog on a high quality high protien dog food. Ask a pet store assosicate or your regular vet for a food recommendation. When you buy a better food the dog will have to eat less to get the same amount of energy from the food. The dog has to eat more of the cheaper foods to get the energy it needs from it. Meaning more poop and buying more food. So the cost really evens out. So the lessen your dogs bowel movements get on a better senior dog food. Next talk to your vet they may have a recommendation. If you switch dogs do it slowly by mixing the foods. Start with 10% new 90% old mixed for at least a week until you have switched to 100% new 0% old. Senior foods have more fiber to help with bowel movements. Take the dog outside to go potty more frequently, right before bed time.

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.

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. My dog doesn’t eat, what should I do?
ANSWER : A. If this is a puppy, see a veterinarian immediately. Puppies should want to eat. Common causes for anorexia in puppies include viruses (parvo is a big one), parasitism, and foreign bodies. They need immediate care – go to an emergency vet if yours isn’t open. Puppies can get low blood sugar and dehydration very quickly.

If this is an adult dog and you observe other concerning signs, such as diarrhea or decreased energy, you should see a veterinarian.

If the dog seems otherwise bright and stable, try offering different types of food: wet food, canned tripe, or cooked chicken and rice. Some dogs will go for canned baby food: chicken, turkey, or beef as the main ingredient. Make sure there are no garlic or onions in the ingredients!

Causes of anorexia in adult dogs can range from less serious to severe. Younger dogs are more likely to get into trouble- they tend to eat things they shouldn’t, and can get foreign bodies from eating things like socks, or stomach upset from getting in the trash. Any dog may stop eating due to stress, or just being a picky eater. Middle aged dogs can stop eating when they’re stressed and also have Addison’s disease, which can be fatal. Older dogs tend to stop eating when they develop cancer or renal disease.

There is no one-size-fits-all recipe to know when the right time is to take your dog to the vet. The moral of this story is, if it’s not getting better, your pup feels bad, or you’re worried – go see the vet!

Q. My dog drinks a lot of water, should I worry?
ANSWER : A. Firstly, you should quantify if your dog is actually drinking an excessive amount of water. In a 24 hour period, a dog should drink about 1 fluid ounce (or 30mL) per pound of body weight. Therefore, the recommended amount of water intake (in fluid ounces) equals your dog’s weight (in pounds). For example, if your dog weighs 8 pounds, he/she should drink about a cup of water in a 1 hour period. This will be slightly increased if your dog gets a lot of physical activity or lives outdoors.

You can measure your dog’s water intake the following way: in the morning, measure a specific amount, a little bit more than you think he/she will drink. 24 hours later, measure the remaining amount. If the amount of water your dog drank is significantly greater than it should be, then you should take your dog to a veterinarian.

Causes for mildly increased water consumption include: food changes, increased ambient and body temperature, increased activity, urinary tract infection, and general illness.

Common causes for greatly increased water consumption include: diabetes, urinary tract infection, kidney disease, steroid use, and other systemic diseases. With large increases in water consumption, you will also usually see increased urination. Please take note of urinary patterns to discuss with your vet. Greatly increased drinking and urination is ALWAYS a reason to see a vet.

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. My dog won’t stop eating cat litter, old diapers and she even tried eating glass
ANSWER : A. Don’t let your dog have access to cat liter and old diapers. Have a trash with a lid for the diapers and put a hood on the cat box or put it in a room the dog can’t get to. If your dog is trying to eat other things maybe he’s looking for more nutrients in his diet that his food isn’t giving him. Look for a higher quality high protien food at the pet store. Have someone help you at the pet store pick out a food or ask your regular vet their food recommendation. One with the first ingredent as a meat like deboned chicken. If your dogs foods main ingredient (first one listed) is a corn or chicken by product that is bad. You will need to slowly transition the dogs food over by mixing the foods and slowly adding more new and less old to the food for at least a week.
