Sudden changes in food or consuming spoiled food is one of the main culprits of diarrhea in dogs.

Emotional stress or anxiety can impact a dog’s digestive system and lead to diarrhea.

Chronic conditions affecting the digestive tract, such as inflammatory bowel disease, can cause persistent diarrhea.

If your dog has ingested toxic plants, chemicals, or foreign objects, it can lead to gastrointestinal issues, including diarrhea.

Internal parasites like worms or fleas can irritate your dog’s intestinal tract and result in loose stools.
