Get over it all ready.
Every agility class I've been to has a somewhat different vibe. Some are all business, some very cliquish, some will chat it up the whole hour if given the chance.
Kittie, Abby and I decided to switch nights, same location & instructor, but a different group and totally different vibe. This ended up being the 99% traditional agility dog group. Dogs that bark, and don't scream, proper agility dogs apparently should not scream, or take treats like starved wolves.
I know all of these people, have for years...just have never been in class with them as a group. It felt like the entire topic of conversation revolved around how "troll-like" my dogs are........ They weren't even particularly noisy. Abby gets scared if big dogs get too close to her crate, and Kittie goes berserk right before she runs, they sound kind of funny. I expect people who have never heard them to comment, but really after five or so years, can't people just get over it.
