We are going to start a new product I found so not sure if it works yet, I have an OCD anexity licker... to the point of licking the paint off my kitchen walls and then eating a HUGE hole in the wall!!! And like yours, DO NOT crate him unless you want to clean up the hugest mess of pee and poo you have ever seen!!!!
