Dogs are just like humans in that they can get diarrhea when their diet is changed. Just as our stomachs can get upset when we eat something new, so can your dog’s. The difference is that dogs can’t tell us what’s wrong, so it’s up to us to figure it out.

There are a few reasons why your dog may have diarrhea after you’ve changed their food.


When you change your dog’s food, their digestive system can get upset. This can lead to diarrhea. Diarrhea is the body’s way of getting rid of something that is upsetting the stomach.

If your dog has diarrhea after you change their food, it is best to switch back to their old food and then slowly introduce the new food again.

How Long Does a Dog Usually Have Diarrhea After Changing Food

If your dog has diarrhea after changing food, don’t panic! This is actually quite common and usually nothing to worry about. Diarrhea can occur when a dog’s digestive system is adjusting to new ingredients or a new type of food.

It usually lasts for a few days and should resolve itself within a week or so. If your dog’s diarrhea persists for more than a week or is accompanied by other symptoms like vomiting, weight loss, or lethargy, then it’s time to see the vet.

Why Do Dogs Get Diarrhea When You Change Their Food


How Long Will My Dog Have Diarrhea After Changing Food?

If your dog has diarrhea after changing food, it’s important to monitor their stool and contact your veterinarian if the diarrhea persists for more than a few days or if there are any other concerning symptoms. Diarrhea can be caused by many things, including a sudden change in diet, and it is important to rule out any potential medical causes before making any changes to your dog’s diet. If you are changing your dog’s food, do so gradually over the course of a week or two to give their digestive system time to adjust.

How Do I Stop My Dogs Diarrhea When Switching Food?

There are a few things you can do to help your dog adjust to a new food and avoid diarrhea. Start by slowly transitioning to the new food over the course of a week or two. Mix the new food in with the old food, gradually increasing the amount of new food until it’s all that your dog is eating.

This will give their digestive system time to adjust. In addition, be sure to feed your dog smaller meals more often throughout the day instead of one large meal. This will help them digest their food better and avoid an upset stomach.

Finally, make sure they have plenty of fresh water available at all times to keep them hydrated. If your dog does start having diarrhea after you switch their food, there are some things you can do to help ease their symptoms. First, try feeding them plain white rice mixed with their regular food as this can help bind up loose stools.

You can also give them over-the-counter probiotics designed for dogs which can help restore healthy gut bacteria and calm an upset stomach.

Why Does Changing Dog Food Give Them Diarrhea?

If you’ve ever changed your dog’s food and noticed that they have diarrhea afterwards, you’re not alone. Many dog owners report this happening to their furry friends. But why does it happen?

There are a few possible explanations. First, it could be simply because your dog is not used to the new food. Their digestive system may need some time to adjust to the new ingredients and textures.

This is usually nothing to worry about and will resolve itself within a few days as your dog gets used to the new food. Another possibility is that the new food contains different amounts of fiber than what your dog was previously eating. Fiber helps regulate digestion and too much or too little of it can cause diarrhea.

If you think this might be the case, you can try slowly transitioning your dog to the new food by mixing it with their old food until they’re eating mostly the new stuff. This will give their digestive system time to adjust and hopefully avoid any tummy troubles. Finally, there could be an underlying health issue at play here such as allergies or sensitivities to certain ingredients in the new food.

If you suspect this is the case, it’s best to consult with your veterinarian who can help you figure out what’s going on and find a food that agrees with your pup’s stomach.

Should I Change My Dog Food If He Has Diarrhea?

If your dog has diarrhea, you may be wondering if you should change his food. The answer to this question depends on a few factors. First, you’ll need to determine the cause of the diarrhea.

If it’s due to something he ate or drank, changing his food probably won’t help. However, if the diarrhea is due to an underlying health condition, such as irritable bowel syndrome or pancreatitis, then switching to a different food may be helpful. If you decide to switch your dog’s food, it’s important to do so gradually.

Sudden changes in diet can lead to further gastrointestinal upset. Start by mixing a small amount of the new food in with his old food and gradually increasing the proportion of new over time. This process can take a week or more, so be patient!

If your dog’s diarrhea persists despite changing his food, or if he seems otherwise unwell, please see your veterinarian for advice and treatment.


Dogs may experience diarrhea when their food is changed for several reasons. A sudden change in diet can cause digestive upset and lead to loose stools. Some dogs are also sensitive to certain ingredients in their food, which can cause an allergic reaction and resulting diarrhea.

It’s important to slowly transition your dog to a new food over the course of a week or so to help avoid any stomach trouble. If your dog does have diarrhea after a food switch, be sure to contact your veterinarian.
