Dog Walkers

My small dog does not like small dogs, but is really good with big ones, explains the owner of the small dog, somehow surprised by his dog’s good behavior. That is exactly the opposite that my big dog does, answers the big dog’s owner.  He only attacks bigger than himself. It is not even “pick on someone of your own size” case, and not evens “the grass looks greener on the other side”. but there must be a good saying on that.
