I've been giving Murphy bully sticks, but he downs them in no time. Which leaves him bored so he wants to go outside and eat everything in sight (including rocks). That's not ok with me. He has a TON of toys and chew things, but he has no interest in them. I haven't given him rawhide because I read some posts on here that said they aren't good for dogs. But I really need something bigger than a bully stick to occupy his chewing for a while. Does anyone have any ideas? If I give him a big rawhide bone will it hurt him to chew on?
