Chester and I want to say a quick hello....he is a Boston/Rat Terrier mix. Very intelligent. Most tricks he learns quickly, but a few I am trying to "tweak". He loves to play ball so I usually do some training while we're playing and it works very well. He hates it, however, when I tell him "Last one". He will go to the ball, look at me, then lay down. What a character! I was wondering what other funny reactions your dogs have to certain things.
