They are not the best and they are not the worst. You could definitely do better. The price of these puppies seems high based on their parents accomplishments. Texas is filled with great breeders. I would suggest contacting the local Golden Retriever clubs Dallas-Ft. Worth Metro Golden Retriever Club
or Austin Golden Retriever Club
Things I do like:
The clearances for the parents are mostly in order for the Rayne litter. As noble fan mentioned you need to ask about the dad's eyes.
Things I don't like and would ask questions about
It seems like making puppies is the "hobby" and that does not make you a hobby breeder. The hobby is a discipline in the sport of dogs, like showing in conformation, obiedence, tracking, hunting, etc. The breeding comes later as a way to continue in your chosen sport. They do not talk any where on their site about being active with their dogs other that mentioning the CGC. I my opinion every golden should be able to earn a CGC, so to me that single accomplishment is not a reason to breed a dog.
Rayne's mother was bred despite having a heart murmur. So, the puppy you purchase will have a grand parent with a heart issue. I know she says her vet gave her the ok, but the GRCA COE did not.
Rayne was kept because she was the only girl. That statement just kind of worries me. It seem the only reason she was kept was her ability to make puppies. Sure, she could be the nicest puppy ever, but with out competing with her in some venue, no one knows. They then bred back the same mom and dad to keep a full sister. Why? Very rarely would a breeder want to keep two full sisters to continue a program with. The goal should be to improve each generation. Breeding back and keeping another of the same line is not what I would consider an attempt to move forward in a program.
By several statements, her selection seems based on color. This is the last consideration I would have when keeping a puppy. Yes, we all have preferences, but she is stating color as a reason she is selecting her dogs and not much else. If I have a choice between a dark puppy and a light puppy, I would choose the one that was the most structurally correct. This might be the case, but it is not what she is putting out their publicly.
Haylee's puppies being priced higher. Though no reason is stated for the difference, my guess would be the number of champions behind Haylee. Since there is no evidence that Haylee or Sandler are titled or competing anywhere, this make no since to me. Champions behind a dog mean very little if the parents themselves do not prove themselves as well. This seems like she is cashing in on the work of others.
These would be my talking points with her. She might have great reasons for doing what she is doing with her breeding program. So, I would have a conversation with her. For the price though, I do think you might be able to do better.
Good luck with your search. And of course we will all want to see pictures when you get your new puppy!
