We just got a 4 year old golden retriever. The previous owner mentioned the dog is never comfortable with the vet. Since the golden was an "adult" has only been to vet twice. I just took him to the vet this past week and nearly bit the vet while he was examining his legs. The golden did not back down when the vet reprimanded him. He kept his stare. The vet was extremely concerned about our golden being around children. We have had the golden for two weeks and is fantastic with all of us (especially my children: 8 and 10). Any insights???
