I took Cassius to a trainer Saturday for a consultation. She absolutely loved him (it's difficult not too) and said he had an excellent disposition. He focuses very well and is very bright. Cassius wasn't too fond of her dogs. They were very large, intimidating German Shepards.
He already walks on a leash and knows how to sit on command (it takes a few commands, but he gets it).
We still have a few weeks, so we are going to look around for other trainers.
