Hello, I've read quite a bit on here how much bully's love their antlers and how they are supposed to last especially with heavy chewers. Last night I got one for Buster for the first time and he absolutely went nuts! It's an Antlerz and after about 2 hours he was already about half way through it. It's pretty much the same size as a regular Nylabone but he chewed through it so quick. Has anyone had this happen to them??
