This is why it’s important to know the difference and possible reasons behind the loss of appetite. As we researched, we found a number of the factor which affects dogs in a way that they stop eating food.

One of the symptoms of cancer in dogs is the loss of appetite.

Vaccination Side Effect

Loss of appetite in dogs is one of the most common side effects when it comes to dog vaccines. While this is something we cannot imagine our life without, as it guarantees the health of a dog and everyone around it, it’s also a strong chemical treatment which may affect dog 24 hours from the moment they are injected with it. So, bear in mind they may react to it through refusing food, but there is a trick with this one. When it comes to refusing food as an effect from receiving the injection, it can last up to 24 hours, not longer. Anything longer is a code red, which means you should contact your vet immediately.

Loss of appetite can be a serious indicator that the kidney is failing. A good way to tell if you have this problem is to pay attention to what your body tells you, and see if it’s telling you something different from normal.

A toothache

Probably the most painful one with the dogs, dental issues are the worst. They require immediate attention, and don’t fool yourself, they won’t just go away. It may be a broken tooth, but it can also indicate periodontal disease in their mouth.


Another reason why your dog may not be eating as much as before is arthritis, and this is not something to ignore. Still, that’s not the only problem listed as a reason behind appetite loss. Make sure to exclude hip dysplasia before you begin discussing the possibility of arthritis with your vet.

Pain due to an injury

Dogs are strange when it comes to expressing the pain, which is why not eating plays such an important role in figuring out what’s going on. If your dog skipped a meal, you should inspect them for possible injury, while this may ask for a vet, it may also be something you can fix by yourself.

Change of environment

Dogs take a change of environment differently. Sometimes, it’s the owner that needs to give it attention in order for it to start eating, but this sudden change in food preference happens more often if we leave a dog with a dog sitter or a different family. It’s hard to imagine what dog is going through at the moment, but one must also assume there may be other factors in play, such as lack of attention from the pet sitter.

While this is something we cannot directly change, given we’re absent at the moment, it’s something we can influence over the phone. Perhaps, you could tell your pet sitter to feed your dog their favorite food. (viagra online) Let’s not forget this can also happen if you’ve recently moved to a different apartment, and your dog is still adjusting. Try using comfort food and let them know you’re there in this case.

Being a picky eater

Sometimes, the dog will refuse food just because they don’t like it, and this can happen with older dogs. You may have switched the cans, or you wanted to implement certain nutrients into their daily diet, but don’t think they won’t notice it. It’s not as simple as they may be allergic to this new stuff you served them, which is why you need to pay attention to other signs as well. They may be trying to say something as well, and if nothing, they deserve to be treated with respect when it comes to food.

In any case, try switching back to the old stuff, and see if it’s worth it, and if not, consult with the professional to see how you could implement certain nutrients to your dog diet. While it may look like your dog is just spoiled, it can also point out to certain deficiencies, which is why consultation is mandatory.


When it comes to the loss of appetite in dogs, there are more than a few factors that could be the cause of it, and ruling either of them out without professional help is not something you should do.

Anorexia can be found with dogs as well, and your dog may be experiencing it.
