We have had rescue dogs, pre-loved dogs and recently purchased a puppy from a breeder. I would be happy to be home-checked in any of the above circumstances.
Whilst we weren't home checked by our puppy's breeder, we were required to provide references from our vet, give details of local training classes and our existing exercise regime. We also had to give evidence that we had experience of the breed (border collie).
We were asked to visit the breeder at least twice to see our puppy and be interviewed. On both occasions we saw mum, grandad, and the puppies. Dad's owner, who lived in the neighbouring village, kindly brought him along to meet us. Our breeder normally has homes for her pups before they are born, but one of her prospective owners pulled out because she wanted a male puppy (already had 2 un-neutered males) and the litter was all female. Otherwise, we would have been interviewed and vetted BEFORE the puppies had been born.
Our breeder kept in regular contact via email and You Tube, uploading videos of all the puppies. Our puppy had all the tests recommended for her breed and we were kept informed of when they were taking place and the results. When we picked up our puppy, we were given a file containing her pedigree and test details as well as those of her parents; feeding and training advice and tips as well as grooming guidelines. Furthermore, our breeder is happy to be contacted for further advice and help. She provides back up for life and would take back our puppy at any stage of her life if we were unable to keep her for some reason.
Although our puppy was not cheap, I doubt her breeder made much, if any, money as her testing and monitoring was thorough. Our breeder shows her dogs and competes in agility and is seeking to improve the breed.
