Diarrhea in a puppy is treated by avoiding food for 12 to 24 hours to allow the gastrointestinal tract to rest and providing drinking water to prevent dehydration, according to WebMD. Veterinary attention is necessary if diarrhea lasts for more than 24 hours or is accompanied by additional symptoms of illness.
Careful attention should be given to puppies with diarrhea as their symptoms can become severe in a short amount of time. Young puppies are more susceptible than older dogs to developing infectious and parasitic-related diarrhea, states WebMD. A veterinarian may take blood, urine or feces samples to pinpoint the cause of illness when examining dogs with diarrhea.
Diarrhea in dogs can be caused by sudden changes in diet or the ingestion of garbage or spoiled food, toxic plant material and non-food foreign objects. Diarrhea is a possible symptom of underlying illnesses including bacterial or viral infections, internal parasites, inflammatory bowel disease, cancer of the GI tract, liver disease, kidney disease and colitis, states PetMD.
By making gradual changes in diet when switching dog food and not allowing a dog to eat scraps or scavenged food there is less risk of dysfunction of the GI tract resulting in diarrhea, reports WebMD. Keeping up to date with vaccinations and de-worming sessions are additional prevention measures.
