I'd take my dog(crated in the vehicle) and bring him out only when I knew it was ok and after learning the rules.
If I was asked to leave my dog home, then I'd do so....but as long as you have a crate and the temps aren't extreme, always a good thing to have your dog with you!
Where I train barking is an issue, so a dog barking in a crate is discouraged and bark collars are a necessity for some.
I wouldn't tolerate my dog being noisy, especially if I were visiting a new group/
I got invited to visit the club in the area, and they told me not to bring my dog for the first visit. If I liked the club, and was still interested, they said then I'd bring my dog the next time to see if he likes it.
I would ask the club what they want you to do. Our club wants to meet your dog and do some testing so we have you bring them. We do require they be crated, stay in that crate except to potty and are leashed when out.
I can understand the 'no meeting after' thing. Grim is just fine before... and there are people out with dogs before... but after? Grim's high as a kite and I even have my wife put away her 'alpha bitch' who likes to push him now and then before we get home. They may play just fine after... but with all that adrenaline, who can say?
Forgot to answer the question, lol! I ask. If I take, I take in a kennel. Grim doesn't bark while in the kennel, but at my current place some bark the whole time. I don't think that's bad, because it's a distraction they need to get used to.
Barking in crate whether it is from excitement or reactivity should be discouraged. It just drains energy that could be placed into the training. And I hate it when I walk by a ride and it explodes in a barkfest. I take wide berths not to set them off, but many dogs just go off when a leaf blows by.
I parked next to someone at a trial (not many parking options) and his 3 dogs were really reactive. I knew the name of two of them so told them to quiet, which worked! And he knew not to park in the traffic area, he was out in the way back, so they wouldn't go off constantly.
When I first visited the clubs in my area I went alone because I didn't have Berlin yet. Sunday we are going back to the club, and he is coming with partially to work on training and partly for the "socialization" of being around those circumstances (with everyone ignoring him per my trainer's instructions).
Like everyone else has said, I would ask the club. If you are thinking of competing with your current dog, I would assume many clubs would at least want to evaluate.
