I have a cross Border Terrier / Lakeland Terrier, she is called Bracken and she is 10 months old. Last week we had a holiday in cumbria in the Lakedistrict of England so you could say we took her to her native home for a while. Bracken adores our two small children, I think the dog thinks she is a child. If you do not know what a BT looks like if you have ever seen Disney's show "Honey I've Shrunk The kids" the BT dog in the show is the double of Bracken. Even our 2 year old daughter screams at the telly when it comes on "Bracken's on the telly."
I think the BT's are distantly related to cairns, they certainly have the same character.
