I don't advertise with Dogs NSW, only one Whippet breeder does.
You would have to ask the people at Dogs NSW to give out the telephone numbers for others.
I don't advertise with them because I don't plan on having regular litters.
One pup was sold via DOL and the remainder were referrals from other Whippet breeders. I did the same for other breeders when people were looking for particular colours etc.
I only advertised on DOL being in Sydney I had no need to advertise anywhere else.
Screening of potential puppy buyers no matter where they come from is still screening.
I must live in Tassie too because I've never looked at Gumtree or whatever and must admit I wouldn't buy off the Trading Post but I'm not a first time dog purchaser.
