I want to know how to stop my 1yr old black lab from eating her stool and her sister's stool who is a 2yr old black lab. I have tried everything on the market EX: enzymes, forbid, tablets i bought at the pet store, and meat tenderizer. I treated both dogs. My lb did not start this bad habit untill she was 11 mos old.
It sounds like you did it all. You can also try walking your pets on a leash so you have more control over what goes in the mouth. When either dog makes a bowel movement then give her a dog treat. A treat in the mouth is better then stool. Of course keep the yard stool free. Good luck, vetcare
