Our little Gizmo starts chewing his disposable we-wee pad. He was doing good making pee & poop there. Until one day, he had little pieces of cottons from the pad in his mouth and all around it. I was afraid that he might choke on it that I bought the washable pads. Yap, he could not chew on it but he also does not want to go there anymore ( even if I sprayed it with the we-wee aid). Now he goes on his bed which I have to wash all the time. Can anybody help me please. We are first time puppy owner and he is 14 weeks old baby boy. Thank you
