My rott puppies love to chew on Pig Ears. It satisfies their need to chew and keeps them from chewing other things like shoes, furniture, etc. It's not messy, they are relatively cheap ( I get em 2 for a dollar ) and it's the only thing they seem to like. They have refused the nylabones, they won't touch the rawhide bones whether or not they are flavored, and those rubber Kong toys are also ignored.
