Recently I've been looking for a puppy. I found a litter advertised and after making contact and asking about parents etc I agreed to pay a reserve fee for a female puppy. It was from a family, not a professional breeder. I went to visit last weekend, the puppies were 5 and a half weeks old. They all looked healthy although my reserved pup had some tear stains, which I'm not too concerned about. I was told the mother had been taken away from the pups at 4 weeks as she was losing a lot of weight. I did see her and certainly her ribs were showing. The father was present and seemed healthy. I got a text last night saying the pups had been to the vet and had their 1st vaccination and been chipped and were now ready for collection - at 6 weeks. I replied that i felt this was too early and was told "no worries, collect any time you want" I'm happy about the health of the pup and I don't believe it's a front for a puppy mill but I'm not confident about the breeder. Should I walk away?
