First of all, sorry for the loss of your family’s golden. I wouldn’t wish that on anyone. They really are family members.
I’m a big time golden retriever person – currently have 2 and had them throughout my younger years as well. I’m also a very active member of the Duluth Retriever Club and am involved in the field trial and hunt test game.
When you say Frisbee goldens, I’m assuming you’re talking about Darrel Frisbee? He was a field trial guy, so his dogs had way more drive and go than a “regular” golden.
Will you do any hunting or are you just looking for a good family/house dog? There’s a couple field bred golden lines I could recommend to you, but they’re going to be a lot more expensive than a regular golden (typically in the $3-4k range). If you will do any hunting or field work, its well worth the additional investment to get a field bred golden.
If you’re just looking for a good house dog, I wouldn’t go the field bred route. It’s borderline unfair to a dog with that pedigree to be stuck in the house their whole life without any outlet to hunting or field work to use that drive they have. Kind of like buying a race car to run to the grocery store once or twice a week… Very unfair to the dog in my opinion.
If you’re just looking for a house dog, I’d start by looking for AKC lines. Then go on a site visit and meet the sire and dam and see the dogs temperament and trainability in person as well as what kind of operation the breeder has. You’ll be able to tell very quickly if they’re just in it for the money or if they really care about their line/pedigree. If the breeder doesn’t do any screening on the home/environment the dog is going into, I’d walk away.
