We have our second golden (well, 1st looked and acted a lot like a golden, but all we know is his mom was 1/2 golden). Our favorite breed in terms of personality.
My suggestion, try to get a smaller one. Mine is no more than 60# or so. A very manageable size. Seems the current trend is for massiveness.
I’m not certain of this, but I have heard several times that there are sort of 2 types of golden. One is larger and blockier, and is bred for conformation shows. The other is somewhat smaller and sleeker, and bred for field work and trials. Not sure of the truth of this. But if true, mine is definitely the second type.
Also, when we bought Daisy, the trend was for very light blond goldens. So we got a deal because she is dark red, almost Irish Setter colored.
Breeders will often give loer prices on dogs that are “non-show” quality. And there are a number of amateur breeders, folk who love their golden so much they (misguidedly) think what the world really needs is their dog’s progeny. I have also known several very nice dogs that are golden mixes - most commonly crossed with labs. Very nice personalities and very good looking.
My anecdotal info and experience is that goldens tend to be less chewy as pups than labs. My current dog - now 6, never damaged a thing. However, she loves to carry things in her mouth - especially dishtowels and dirty laundry. Never chews them, just likes to carry them. Several other golden owners have described the same.
At 7, my dog is seeming to show some signs of arthritis. My vet says I shouldn’t have run her as much as I did when she was young - especially on hard surfaces.
Don’t think that a golden will automatically accept new babies, and willingly act as a playset. They generally will, but they will need to be shown their position in the pack with every new addition. And kids and visitors need to be instructed on how to deal with the dog. Any list of dogbite stats will show a large number of bites by goldens. Due in large part to their popilarity, but also, I suspect, to people thinking their big cuddly ball of fluff would never hurt a kid. You can never be certain how a dog will react to various things, or how a kid can unthinkingly provoke a dog.
