There was a lovely Cavalier(blenheim)working at the show I was judging at last weekend, not in my class as he's a dog & I was judging a bitch class
If you want to show & do obedience then my advice is don't do a sit at halts but a stand for showing. Once your puppy has got the stand sorted then you can start teaching the sit, doing the sit first will mean she thinks you want her to sit when you stand still in the breed ring I always do the stand first with my show dogs & then the sit later. It means I have a good stand for the showring
