Home treatment for diarrhea in dogs requires withholding food for 12 to 24 hours while the diarrhea is active and maintaining a fresh supply of water to prevent dehydration, according to WebMD. If the diarrhea lasts more than one day, it may indicate a serious condition that requires veterinary attention.
Causes for diarrhea in dogs stem from issues in the small or large intestine, states PetMD. When the condition originates in the small intestine, dogs may experience weight loss, vomiting, an abnormally large volume of feces and an increase in frequency of defecation. Other symptoms include gaseous sounds from the gut and black, tarry stools. Dogs suffering with small intestine issues often have an increase in appetite because of poor digestion.
Symptoms of diarrhea originating in the large intestine include bright red blood or mucus in the stool, straining to defecate, or pain during defecation, notes PetMD. There may be an abnormally smaller volume of feces.
Veterinary treatment for diarrhea depends on the cause, states PetMD. Dogs may receive treatment for parasites or a change in diet. In the most severe cases of intestinal blockage, a veterinarian performs surgery.
Diarrhea prevention entails staying current with vaccinations and following parasite management recommendations, explains WebMD. Other preventative measures include monitoring a dog's diet and restricting access to garbage, spoiled food, dirty water and plant material.
