My 3 year old newfie recently started limping. Luckily, VCA parkwood ruled out hip dysplasia but is recommending x-rays to better understand issue. I'm fine with that but they said they have to sedate him to get x-rays. Anyone with a large breed know if large dogs have to be sedated. Really don't want him sedated unnecessarily. He's an extremely gentle giant, so would gladly lay through xrays. Or could you recommend another vet to get a 2nd opinion? Pup is still running and swimming, so he uses leg, but we are limiting his exercise for now
