I tried pineapple for a month with no success, then added brown rice and still nothing. Mine was a hard core poop eater
. So I finally broke down and did the Forbid from the vet. I treated everyone for 2 full weeks and mine stopped and has not done it since.
My guy came as a pup doing it, I think he learned from his mom. He ate his and everyone elses and decided it was better than dog food so I had to do the Forbid....
