One thing that I have heard is that the vet at our location is great. We met a couple with a $5k show malamute and they go to him with her and love it. They told us that this vet used to see their wolf as well, yep a wolf! I assume that these people can afford to go to any vet and they come to PetSmart.
I am still trying to understand the vaccines thing. I heard about them giving separate shots in one appointment and not combining shots for dogs comfort, but not sure other then that.
