Hi there are loads of BC's in rescue who need forever homes, I hope you consider taking a look at some of them. I would never buy a BC puppy from a breeder whilst I know BC's are pinging off the walls and being destroyed in rescue centres. Every dog I have owned has come from rescue and the animal behaviourists will work with you to find the right partner for you. Its great to and visit and play and take time getting it right. The canine behaviourists they don't want to see their rescued dogs come back and are in a great position to give offer expert help.
I would never judge anyone for getting a puppy, absolutely each to their own, but would strongly urge people to consider ALL the options before buying a pup when so many farm BCs are in rescue.

Good luck x
