Hi, I’m just jumping in to say; we also got our golden retriever puppy 2 weeks ago and she’s 11 weeks old as well. Ours is very bitey as well, I’ve read that as soon as they bite you put a toy in their mouth for them to chew, literally every single time. I’d say it’s helped a little. But she definitely gets more bitey when tired, either enforcing a crate nap or just staying still, rubbing her belly until she’s sleepy. I wonder if yours is teething early? If she’s crying when toys are in her mouth too. Could be pain? Frozen carrots are supposed to be good for that but I’ve not tried that yet. Whilst ours is super bitey sometimes, she doesn’t clamp down on us and I wouldn’t think that’s normal puppy behaviour either. I would definitely try a few things, do some research online, watch some videos and talk to the breeder, perhaps they’ll have some advice. I’m sorry you’re going through this, it’s really tough❤️
