How to Identify Common Pet Problems ?

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

The first and most common reason your dog may be throwing up undigested food is that they`re eating too fast. It`s common for dogs to eat fast. Some dogs seem to inhale food without even chewing, and this is a habit you`ll want to work to break because eating too fast can lead to more than just regurgitation.
If your dog is vomiting up his food often, you should call your veterinarian. You should immediately contact your veterinarian if there is blood in the vomit, your pet is acting like he wants to throw up but cannot, you feel he has eaten something toxic, if he has a fever, if he is in pain, or if he is bloated.
This is often a sign of reverse motility, and vomiting food several hours after eating can often be seen at night when dogs lay down making digestion harder and easier for a dog`s stomach contents to reflux back up causing irritation of the esophagus and predisposing to vomiting.
One of the answers to “why does my puppy not chew his food?” could be his genes. Your pet`s esophagus can expand to swallow large meal portions at a time. It`s something people can`t do, but for them, it`s in their genes. Yes, they can seem strange at times, but it`s important to understand why.
If your dog is throwing up food and also has any of these symptoms, take them to the vet. If your dog throws up and continues eating with normal bowel movements, it might just be an isolated incident. But if your dog is vomiting and not eating, you should check with your vet to rule out serious conditions.
Conclusion. Yes, dogs do like to toss their food around and it could be for one of several reasons. Either they`re bored, playing, or don`t like the taste of what you`re trying to feed them. There is, as always, another solution.
Your puppy might throw up as the result of starting a new food, eating too fast, stress, or food sensitivities. You`ll want to take your puppy to the vet right away if they`ve eaten a foreign body or something toxic; there is blood in their vomit; their gums are pale or white; or if they are lethargic.
Dogs Are Not Designed to Chew Their Food

It is very rare that a dog will chew up its food, so you should not consider your dog`s eating behavior strange or problematic if they are not chewing. The only time that swallowing food whole is an issue is if your dog is choking, vomiting, or refusing to eat their food.

The stomach is usually empty 6 to 8 hours after eating. Vomiting of food when the stomach should be empty suggests an obstruction of the stomach or abnormal motion of the stomach muscles that normally grind food and push the ground food out of the stomach.
Slow-feeder bowls, aka puzzle bowls, can help. Puzzle toys add obstacles to the bowls in the form of pins or mazes that slow your dog`s mouth and force your pup to chew his food. Even if he only breaks the kibble into one or two smaller bites, that`s helpful.
If your puppy is teething, try freezing a rubber toy; the cold rubber will soothe their gums. As always, supervise your puppy so they don`t chew and swallow any pieces. Make items unpleasant to your dog. Furniture and other items can be coated with a taste deterrent (such as Bitter Apple®) to make them unappealing.
Increased stomach acid: When a dog`s stomach is empty, it can lead to an accumulation of gastric acid. Excess stomach acid without food to digest causes irritation of the stomach lining and this can cause dogs to vomit from hunger.
Switching your dog`s food abruptly can cause gastrointestinal upset such as vomiting, diarrhea, and a decreased appetite. Any time you decide to change your dog`s food, you should transition to the new diet gradually in order to give your dog`s system time to adjust to the change.
If you notice your dog has trouble chewing, check his mouth for any signs indicating the presence of a problem, such as swelling and/or inflammation of structures in the mouth including the gums, fractured or missing teeth, bleeding gums, and other abnormalities.
Your puppy might always be hungry because they need more daily calories. They may also have adopted bad habits caused through eating human food. Some dogs and puppies will naturally be more prone to food obsession. It`s imperative to fulfill your puppy`s daily needs and stick to a mealtime schedule.
Don`t leave food out for your dog to graze on — take it back within 10 minutes if it hasn`t been eaten to help cement the idea of mealtimes. Use your dog`s kibble as treats, and only offer meals for short periods of time. This leaves your dog no choice but to eat their food and hopefully get used to it.
In most cases, when a dog throws up due to eating something they shouldn`t, their body does what it needs to do to get rid of the toxic substance. If it`s a one-time occurrence and your pet otherwise acts normally, try withholding food for about 12 hours to give their tummy some rest, suggests Sheen.
Eggs are high in protein and contain many essential fatty acids and essential amino acids. This makes them a yummy — and healthy — snack when cooked or boiled. In fact, eggs may even be able to help settle your dog`s upset stomach and can also be an important source of protein in some commercial dog foods.
Dogs find that meals are more fun with others,” Semel tells The Dodo. “By nature, dogs are social creatures and the company can motivate them to eat.” If you don`t mind hanging out while he eats, there`s no harm in being in the room during mealtime.
Chewing accomplishes a number of things for a dog. For young dogs, it`s a way to relieve pain that might be caused by incoming teeth. For older dogs, it`s nature`s way of keeping jaws strong and teeth clean. Chewing also combats boredom and can relieve mild anxiety or frustration.
The answer has to do with smell. Although a dog`s ability to taste is roughly a fraction of a human`s, his sense of smell is up to one million times stronger. Smell and taste are very closely related, and dogs can actually taste foods through their sense of smell with a special organ along the dog`s palate.
But to your dog eating vomit isn`t weird at all, it`s a natural behavior. Dogs eat their own vomit because to them it`s seen as a food source. When pups are being weaned mother dogs will regurgitate food for their young to help them adjust to eating solid foods.
Puppy teething

Teething for puppies occurs between three and seven months of age when puppies have an uncontrollable urge to chew to relieve some of the discomfort in their gums. Chewing also facilitates the removal of puppy teeth and the eruption of the adult set.

Q. We have a 4 yr old lab-pit mix we raise from 6 weeks.If my husband tries to take hin by the collar and make him go out to pottie he growls.Problem?
ANSWER : A. This is not good behavior. Rather than take him by the collar, call him to come with you. If he’s not good about coming when called, you can work on that. Keeps treats on hand to to entice him out and reward him when he does go potty and he’ll come to look forward to it. Clicker training is another great way to teach a dog all kinds of things, from obedience to tricks.

Have treats on hand that you know he loves, then simply click and treat. He will come to associate the sound with getting a treat. Start putting distance between you so he has to come to you. Call and click and when he comes to you for that treat, treat him and give him lots of praise. Move to hiding somewhere in the house, call and click. When he comes to you reliably inside when you call, click and treat. When this behavior is consistent, move outdoors with a very long leash. Call and click, if he doesn’t respond, give a light tug on the leash. If he takes even a single step toward you, click, treat and lots of praise. Keep doing this until he comes eagerly. Next, try him off-leash in a securely fenced area. Call and click. At this point he should be responding well and coming easily to the call and click. If he does not, go back to the last step he performed reliably and work on that again until he responds well. Eventually, you can start not treating him every time, but still praise him. Gradually lessen the frequency of the treats until he comes just to the click and praise.

Keep training sessions short, ten or fifteen minutes to start, no more than 30 minutes at a time and do it a few times a day. Try not to do it any time he is overly excited so that he can pay attention to you. Always end a training session on a good note, even if it is just getting him to do something he already does well on command. And never, NEVER punish a dog when they come to you, no matter how far they’ve made you chase them, no matter how frustrated and angry you might be. That teaches your dog that coming to you is a bad thing.

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 much dry kitten food should my 16 week old kitten be eating?
ANSWER : A. It would actually be better to feed your kitten canned food, as dry food has a lot of carbohydrates. Cats are obligatory carnivores, and not carb-eaters. In order to give you an amount to feed for dry food I would need to know which food you are feeding as they are all different. I suggest you check on the cat food bag. If the bag does not give you an amount, I would not trust it to be a complete food. You should then get a food from a reputable company such as Hill’s Science diet, or similar. As for wet food feed three times daily around 2oz each time, best to feed the pate style food.

Q. My cat can only eat strained baby food consistency food. What do I add to strained meat to give her what she needs? She is a torti Persian 5 lbs
ANSWER : A. You should be offering her some wet cat food. Any brand is okay, but you could find a high quality food if you look hard. Cats prefer getting their water from their food, so it’s important to use wet food for a cat instead of just dry food. It’s okay to feed her white meat chicken, and things like that if you want, but you should definitely be feeding some sort of CAT FOOD.. and I bet wet food would be appealing to her considering it’s very moist, like baby food. You can even mash it up further, and look for a food that is really liquidy.

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. Looking for a dog food with no grains, no sugars and no yeast for a 6 month old Pit Bull pup with grain and yeast allergies. Any recommendations?
ANSWER : A. Many high end brands such as Taste of the Wild and others found at premium pet stores may have the options you need in a dog food. There are also some canned dog foods available that are 95% meat and are a meat source only with added vitamins and minerals and no extra ingredients. These are best as an additive, but can be used as a longer term pet food with supplementation or monitoring from your vet for any signs of ill health.

Costco also carries a completely grain-free dog food under the brand Kirkland Signature Nature’s Domain. They offer several flavors such as turkey, salmon, beef and chicken. The ingredients do appear to have natural probiotics in them (bacteria designed to help aid in digestion) but does not appear to have any added sugars or yeast products like other high end foods. The only downside? It is recommended for dogs one year and up, so ask your vet prior to switching.
