I had a golden retriever who ate poo everyday. We try the stuff from the vet. It had to go into each dogs dinner. It was supposed to make the poo taste bad(as if it didn't already). He still thought it was great! I then tried putting cayenne pepper or hot sauce on top to see if he would still eat it. Oh boy! He thought wow international poo today!! I gave up after that. Just tried to pick them up daily. Make sure you don't eat some fudge the same time you catch them eating poo!
