What Exactly is Pet Diarrhea?
All pets experience an episode of diarrhea at some point in their lives. Diarrhea usually occurs when the absorption of nutrients from the digested food material is impaired or interrupted. Digesta then accumulates in the intestines, leading to excessive water moving into the intestines. The end result is loose watery feces. In short anything that inflames or irritates the lining of your pet's intestines will cause diarrhea.
Most bouts of diarrhea are associated with a problem in the diet. For pets, who don't care what they eat (eating garbage, spoiled or rotten food, scavenging) is at the top of the list of probable causes of diarrhea. Other dietary problems include a sudden diet change, overeating, or consuming too much human food.
