Constant diarrhea

Diarrhea can be caused by many things including a change in diet or stress. If you notice that your pet keeps having diarrhea after every meal, it could mean they have a digestive problem. If this is the case, you should consult with your veterinarian as soon as possible. However, if your dog only has diarrhea occasionally and it goes away once they are finished eating, it could be a case of intolerance and you should consider changing its diet first.

Allergy symptoms

Another common sign of dietary intolerance is vomiting and constant itching. In these cases, it is best to consult with an expert before changing the diet of your pet. However, if all else fails and you notice these symptoms after every meal, it may be best to change their diet themselves first to see if it helps alleviate their symptoms.

Sometimes it is just a case of intolerance that can be solved with a change of diet. However, always consult with a vet if you have any doubts about your dog’s health.

Excessive Stools

When your pet poops more than usual, it is a sign that something is wrong with its diet. Excessive shits can cause diarrhea in dogs and other gastrointestinal issues. The problem may originate from the type of food you are giving or the food quality.


Another sign is vomiting. Regurgitation is not only unpleasant but very dangerous for your dog. It can cause dehydration, vomiting, and other problems. There are many regurgitation causes, including a diet change, stress, anxiety, and even heart problems.

Tongue Color Changes

As you might know, pink is the normal color of a dog’s tongue. A reddish-brown color indicates that your pet has been eating too much of something toxic. However, if your dog’s tongue is white, gray, or black, it means that something is wrong with its diet. This condition can also be a sign of an illness.

Here, you should remember that some breeds have black or blue tongue such as a Chow chow, so, make sure before concluding it.

Dry Skin

Your pet can develop dry skin due to a poor diet. Dogs with sensitive skin should be given a grain-free diet to maintain their hydration level. They might need this because their food lacks essential nutrients such as omega-3 fatty acids and vitamin E.

Thick Fur

The thick fur is another sign that your pet needs a different diet. If your dog has too many oily meals, its fur will get greasy and dirty which can cause itching and interfere with your dog’s daily routine. Too much fat can also lead to pancreatitis.

Wrinkles and Dry Eyes

If you notice wrinkles on your dog’s skin and dry eyes, it could be a result of a bad diet. It is recommended to give your pet food that contains antioxidants such as blueberries, green tea, pomegranate, and cranberry. Also, avoid giving your dog too much salt as it can cause eye dryness.

Constant Panting

Panting is one of the signs that your pet needs a different diet. If you find yourself wondering why the heck your dog is panting, try to find out if it is warm or not. If yes, check if its water bowl is filled up with fresh water and make sure the supply of fresh water is not stopped.

If it is not hot outside and your dog’s water bowl is empty, try to figure out why it is panting. It could be caused by a bad diet or other health issues.


Just like humans, dogs need a good, healthy, balanced diet to maintain good health. Now it is important to note that dogs can’t eat the same things that we humans do, so make sure you do some research on what dogs can and can’t eat. Not only can it cause them minor health issues but it can also cause them to get really sick and die.

No pet owner wants that to happen to their furry companion, so make sure you really research what to feed your dog. These minor problems are usually because your dog will be deficient in a certain vitamin or mineral. Thankfully, these problems are easily fixed by adjusting your pet’s diet.

If you feel that there is a more serious underlying issue, make sure to consult with a veterinarian as soon as possible. Dogs are man’s best friend, so make sure to take care of yours and feed them as healthily as possible.
