Leroy loves the Nylabones, for some strange reason he does not really care for real bones of any kind. And he is weird when it comes to anything edible for example he loved the edible Nylabones the 1st one or two times but the last one I gave him he just was not interested in, barely chewed on it and it just kinda sat there. Same thing with the Moozles from Merrick, he just ate the first one right up but the second one again not really interested. Not sure why he does this. As we speak he is going to town on a Nylabone,lol. Oh he also likes the everlasting treat ball, I have even seen him chew on it without any of the treat discs inside.
