Sorry truthseeker you took me up wrong, I didn't imply the lurchers / pointers were the unsuitable dogs (although 8 out of 12 dogs were lurchers which was strange I thought), there was those and other unsuitable dogs. Eg I asked about a particular dog and was told he came from an abused background and could not be rehomed except to someone expert in rehabilitation (yet was advertised for a loving home) Anyway I totally take your point about puppy farmers on done deal and to avoid it people need to follow guidelines like visiting the person (not doing the deal in a car park etc) and seeing the mother with the puppy etc, like olddoll says. And I agree people should be responsible before getting a dog but most dog owners don't go to the vet until the dog is sick so yes I did think pre-registering was a bit extreme. I don't include myself in that since I come from a family with happy dogs as pets and so does my boyfriend.
Ironically your local dog shelter was doing exactly what a puppy farmer will not do i.e. taking the time to get to know the dogs in their care, learn the individual personalities, piece together each dog's background, and then give you informed, unbiased advice about the suitability of a dog.
My experience of the DSPCA is that they get to know their dogs really well before adopting them out, and give really useful advice. My experience of the myriad lurchers and greyhounds I've seen there is that they are virtually universally great dogs - even those lurchers and greyhounds that have had traumatic backgrounds tend to cower and be afraid rather than display aggression, which I've seen other breeds do if they've been abused in the past.
I have to say, if I was choosing I'd go for a quiet, intelligent, gentle lurcher everyday over a frankly rather stupid, disease-prone cavalier king charles - but that's just me!
