congratulations!! Connor is a very handsome boy! Give him time. We have show dogs (collies) and they take a little time to come around. Do the Obed or agility with him, that will help.
Our 3 year old male (who is not fixed) marked at first, now he does not because he quickly learned our house rules. I am sure Connor will be the same. The biggest thing to remember is just as if he was a pup, crate him if you can't watch him right now.
When they come to us as adults (ours was 13 months when we got him, also was a Ch.) we sometimes forget that they need to learn our house rules, even if they were good for the breeder.
Since we have had our dog we have had two other pups from our breeder for my daughter to help train and show. Soon she will be *trading in* the pup for an adult who is ready to show and win!! Each time a new dog comes into the house we have to stop and remember that they all need to learn our house rules and cannot be trusted alone.
