Accent is a meat tenderizer that is often added to a dogs food to change the flavor of what comes out. It is thought that if the flavor that comes out tastes different that it may be more unappealing and they will not want to eat their stools. Unfortunately it doesn't always work and you have to use it all the time and with all the dogs and sometimes cats if the dogs are eating cat poo also. It is a condition called Corprophagia. Here is a link that explains more about this and what can be tried to help them stop eating stools. I hope it helps.
