Nice dogs them mate, I never put collie into my bulls thinking I didn't want them to have too much brain lol, we did a lot down south and they could get on 4 to 5 a night all ways single handed but some lads back then said the collie bulls were the best they have owned. Here one of the last I bred out of a 8 year old bitch about 10 ago , not my pic I didn't take them back then.
