Most vets know dogs in general but you can't expect them to know everything about your breed. Follow your breeder's advice. They know through years of experience what is best for their breed. A veterinarian who is also a breeder is ideal. When your pup turns 2 years old, you should follow up with OFA hip and elbow checks, CERF-eye checks and report the results to your breeder.
Puppy skin is extremely sensitive.
Use natural soaps from a health food store such as Tee Tree Oil or even very diluted Joy. Flea dip,use flea shampoos or sprays. Always go at the pup's pace. Never force or reinforce negative behavior. Common sense is your best guide.
