Troy - Goldendoodles Stud Dog in Huntington, NY

I am asking for $350 and pick of the litter. Troy is a calm, retired service dog, affectionate, f1b goldendoodle. He only barked 4 times in his life and yes I counted lol. I prefer to breed him with the following Bernese Mountain Dog, English Golden, Golden Retriever. He is up to date with the vet and has AKC parents. I attached his photos and what his puppies would look like. If photos dont show please let me know. I have plenty.
