I'd say the two most popular breeds on the forum seem to be BTs and Spaniels (working, cocker, springer, etc) and on a forum where you're likely to come across people that love the outdoors, these are the kind of dogs the members are likely to have.
I'd decided many years ago that when it came to having a dog, I was going to have a BT - because I'd had two clients in a row with BTs (both vets, friends of one another) - and one in particular would sit with me all day in the room I was working while I sawed, nailed, sanded and generally crashed around. She would come for a cuddle when asked - covered in sawdust. The other was similarly chilled out.
The photos of some of them on STW reinforced my liking for the breed - I think they're a fantastic looking dog - I like the scruffiness, the cute face, the hardiness and the character of the breed. We've had Molly for a year now and to be honest, I'm only kicking myself for not having had one sooner.
You won't be sorry after getting one. I'd just advise that you're pretty hard on it when you get it as a puppy - well, not hard so to speak, but strict. Of course, it's most difficult to be strict when it's a puppy and if you have kids, even harder - because it's very tempting to constantly cuddle it and spoil it. But a few months of being strict and disciplined, means (IME) that you get a dog that looks up to you and wants to please.
As with any terrier breed - your most important command is recall. We reinforced this over and over again. And then a bit more. Second to that, socialise, socialise, socialise. Terriers that don't get on with other dogs end up getting into a lot of trouble - or you end up having to have it on a leash forever, which while pleasing quite a lot of STW, is a pain in the arse.
Best of luck with finding a pup. We're in Bristol if you're ever nearby and want to meet one - but from the STW BT Club, there's bound to be someone near you with one.
Happy Christmas from Molly:
