I dont live in the south west, I am from n.ireland.£300 is an average price where I come from...
If you are basing your "average" on classified adverts, then this may be misleading; reputable breeders have a waiting list and don't need to advertise, so you are not seeing a "true" price - how many breeders have you contacted?
I remember how concerned I was about price, as it a huge amount to part with in cash to someone you don't know - I realised after being a member of COL for a while that "getting a good deal" is immaterial; there are far more important things, and if it means saving for a bit longer in order to make sure that the sire, bitch and puppies are well bred, healthy and of good temperament then that is what we would do
