Diarrhea, gassiness, and vomiting will become a thing of the past. The limited ingredient list also makes this food great for dogs who are prone to various food allergies.

The main ingredient is cage-free turkey. Why is the label “cage-free” important?

Turkeys that grew up in a cage didn’t move a lot as they lived in tight spaces.

This can influence the quality of the meat, as it can develop certain chemical abnormalities. You probably wouldn’t want that kind of food anywhere near your canine friend!

What Causes a Sensitive Stomach among Dogs


There are a number of reasons why your dog might have digestion problems. Diarrhea is a common problem among canines and it’s always recommended that you take your dog to a vet. However, here are some of the usual offenders to this… explosive issue.


One of the most common causes of diarrhea and other stomach problems are allergies. Some dogs simply can’t take all foods. Usually, the problem lies in the protein source. Most dogs have problems with beef, but that varies from canine to canine.

Food allergies must be diagnosed early on. Contrary to some beliefs, dogs don’t become cured of allergies if they constantly exposed to the source. Completely opposite, the allergies will only get worse. Sometimes, untreated allergies may even cause death. This is why it’s important to always feed your sensitive friend with the best dog food for diarrhea.


Look at your pup’s bum. If you see white, rice-like bits, your dog may have tapeworms.  Tapeworms infect intestines when your dog eats something with their eggs. Another tapeworm hosts are adult fleas. If your dog has a flea problem and cleans himself, he may likely end with tapeworms in their stomach. Infected dogs will lose weight, their appetite will drop and they’ll have a bad case of diarrhea. [1]

Food Intolerance

Sometimes, dogs don’t have any allergies and are free of parasites but still have diarrhea. This might mean that they have problems digesting certain ingredients.

Once again, the most common food to cause this is the protein source. Other ingredients that tend to cause problems are grains and fats. The only way to fix this is to get rid of these ingredients when it comes to your dog’s diet. With no exception! For example, if your dog can’t digest beef, switch to chicken or salmon.


Despite what many think, dogs can feel some emotions similar to humans. For example, if your dog has problems with separation anxiety, they might vomit or have other stomach issues.

The same will happen if he’s had some traumatic experience, such as a close encounter with a firecracker. Not only that, but stressed dogs can get gassy. Try to calm your dog, and use the right food to stop further stomach irritations.



It would be better to take your dog to the nearest veterinarian in your area, without wasting time. A pro vet can diagnose the root cause of your dog’s painful tummy.

The second best thing is to find the best dog food for diarrhea that will suit his needs.

The food of our choice is Purina’s SmartBlend one. Why? Its primary ingredient is salmon, which is known to rarely cause stomach problems.

At the same time, it doesn’t smell as bad as Pro Plan one, and it has carefully planned ingredients. All of this makes it perfect for most dogs’ needs.

However, every animal reacts differently to every food. You must find what works best for you and your four-legged friends.

And if bowel problems don’t go away, this might be the sign of more serious issues. Have your vet on standby at all times.
