We have a 16 week old puppy who growls ferociously when you try to pick her up. If she needs to go up to bed (for example ) we make sure we wake her gently before picking her up but she still really growls. She's not showing her teeth she's just growling but it is getting worse. What can we do about this? Obviously try to limit picking her up so only do it when necessary but don't really want this to escalate. Sometimes she is happy to be picked up for a cuddle so she's not in pain and she's generally a happy busy little pup
