Rectal Bleeding in Dogs

When your dog bleeds from his rectum, the underlying cause can range from an abscess to colitis to hard stools. Stay calm, administer treatment when possible and contact your veterinarian.

Ruptured Sac

A ruptured anal sac oozes blood as the infection drains, and the area must be cleansed with a towel that has been dipped in a saline solution.

Colitis

Colitis causes bloody diarrhea and is treatable with prescription metronidazole. This antibiotic usually eliminates those bouts of loose stools containing mucous and blood.

Constipation

Constipation is uncommon in dogs that are fed and walked regularly, but consumption of bones results in difficult-to-pass feces. Because constipation is rare in dogs, blockage could be the culprit behind straining at the stool, so seek immediate medical attention for your dog.

Trauma

During a dog fight, a canine will attack his opponent's rear haunches, sometimes leaving open gashes in the anus. Use a half-and-half mixture of hydrogen peroxide and water to clean the area.

Next Steps

Many instances of canine rectal bleeding are easily treatable and not serious. Seek the advice of your vet, however, to ensure the good health of your four-legged friend.
