my puppy beagle has been doing this since we got her at 8 weeks old. shes always been on science diet so i know her food is pretty decent. she doesnt eat the other dogs just hers and sometimes she likes the tasty morsels of a cats poop. shes 6 months old now and still doing it. i changed her food a month ago and it didnt help. she loves it, i have to fight her to spit it out which is worse because she usually then runs with it behind the couch so im better off leaving her be.
i just purchased some dis-taste powder that is supposed to make the poopy icky tasting to the dogs, like as if it isnt icky tasting allready...sheesh
ill let you know if it works
