Hi, My 16 month old Belle was examined by an orthopedic vet and i was told she needed TPLO surgery immediately, she wasn't limping had no trouble walking playing, her only problem was she dragged her butt before she would get up.
I decided to take her to a chiropractor, we have only been there 2 times but she told me that this dog did not need any surgery, alot of vets will tell you that just for the money, thats what i think anyway, I would not have any surgery on my newf until i got several opinions, and tried out some other things first.You never get a gaurantee with surgery ,it could turn out worse than what you started with.
I would dump that vet and give him a piece of my mind.
Good Luck
Glory
