My Dog Has Diarrhea But Is Acting Fine: 7 Common Reasons

Wrong Nutrition

The current diarrhea your dog is struggling with may be the result of the human food he ate.

A Change In The Dog’s Diet

Some dogs react in this way to a change in diet. This happens especially often in older dogs.

Foreign Object Ingestion

Intestinal Parasites

Some of the most common intestinal parasites that cause diarrhea are roundworms, giardia, and hookworms.


Some dogs are intolerant to certain medications, so due to medications, you could notice disorders in the dog’s gastrointestinal tract.
