We recently got a mutt from a local farmer. He was glad to give one of three pups away to a good home. Last year my brother paid 650 GBP for a posh dog, but I can't really see the difference. Our pooch also goes woof, wags his tail and thinks we're great. Look out for a local website (if you know what I mean) that people use when they have dogs to give away.

Why don't you contact the TOZ (Towarzystwo Opieki nad Zwierzetami) the equivalent of the RSPCA, it's a human society and they have shelters or contacts with shelters. There are so many homeless dogs looking for love.
