I don't now what it is but people who look for a pet are willing to pay much more than lads that won't a working dog I think the right pup of the right parents is worth its weight in gold.
Could it be a lot of foke swop dogs like they swop they're pants and some jest treat them like a old car if they can make £50 on it it's for sale so they like they're dogs cheap as chips thank god not all working dog lads are that way.
Glad you got good homes for your pups
