I had looked into Goldrush when I first started my search for a golden pup, not knowing anything about them. Since I live in NJ, I was able to visit. They actually have two locations and one is only 20 min. from me. This one had a few sires and moms, and lots of pups. There were at least four litters there and I did not like how they were kept. At night they slept in these huge wire bottomed cages. In one litter, all the pups were about 16 weeks already, and apparently unspoken for. Since all the pups there were weaned, the moms weren't with them, but were in seperate crates in the garage. Two litters were in those huge crates in the garage also. Honestly, I hated the place, and this was before I'd heard anything about cancer in their lines. A female pup was $2,000 and $1800 for a male.
I know two people who have/had Goldrush dogs and one has hip dysplasia (since she was quite young) and the other died of brain cancer at 3 years. I just don't have very good vibes about them.
I had also briefly looked into Goldilocks, whose prices were still a bit higher than I wanted to spend, 1200 for a non-champion sire and $1600 for a champion sired pup. When I asked another NJ breeder about them, she wouldn't give me any details, but wasn't very positive. I honestly can't remember what the issue was, though.
Personally, I like the smaller breeders, not backyard breeders, but hobby breeders. They have all the clearances, can have champion dogs, are involved in the clubs, and take wonderful care of their males and/or females. (this is not to say that a larger breeder doesn't take good care of their dogs, but I just personally didn't like what I saw at Goldrush. Can't speak for Goldilocks)
