Neither of these breeders is a good breeder. In fact both of their websites are great examples of websites that should make you run screaming in the other direction, they are so full of read flags.
Health should be important to all homes but IMHO this is critical for potential service dogs. The nature of service, the cost and the time are such that a SD prospect hit with a diagnosis like dysplsia, sub-aortic stenosis, or progressive Retinal Atrophy would be devistating.
Neither of these breeders does what a breeder with full and verifiable health certifications would do on a website. If you have them, you not only say you do but you provide a way to check them. This is as simple as providing the dogs registration name, though most will include a link right to OFA or to K9Data that then links to OFA. Neither do. Instead the first one says they have it but clearly they don’t since I found the mom to the current litter (Desert Moon Kassi Roo) and she can’t have hip or elbow certifications because she is under age. The second one makes no mention of any health certifications that I could find and hides their dogs behind call names so you can’t look them up.
Here is an example of what you should find on a website where the breeder is doing a good job with health. https://aubridgegoldens.com/our-dogs-2/our-girls/
see the full registration names? See how you click on pictures you go to K9Data that has the dog’s pedigree and health certification are in blue because they hyper link to OFA? That is what you should expect if a good breeder has a full website. Not all good breeders have a full website or a website at all. If there is just a “One sheet” with contact information, you’ll have to reach out and ask for the parents registration names. Also, consider reaching out to the local Golden Retriever clubs for referrals, you might find a great breeder without a website. I will attach some visuals below that might be helpful.
I have to agree, responsibly bred puppies are not usually available without a wait. There are more families looking than there are well bred puppies. Good breeders usually have substantial list before puppies are born and sometimes before the breeding takes place. Considering it takes 4+ months to “make” a puppy to go home, waits of 6 months or more are common with well bred puppies. You will have to be both lucky and diligent in your search if you are looking for a puppy sooner.
