Need advice on aggressive puppy

Hi, I have a 2 month old American staffy puppy and she has displayed some aggression which I understand can be normal but I don’t really know how to handle it. I’ve had multiple staffies growing up and have only known them to be the most beautiful, loving dogs.

My current puppy Nessie is a lot more stubborn than any other dog I’ve had, she does not want to listen, though I do recognise she is still quite young so I haven’t been that concerned.

However, I have noticed that she has been growling at us when she is disturbed during sleep or doesn’t want to get off the lounge. Last night she was all comfy inside and we have been trying to get both dogs (we also have a year old foxy, which she gets on great with) to sleep outside in their kennels.

She has no problem being outside and doesn’t wine when out there, however this routine is still quite new. She wasn’t coming when called so I went over to move her and she growled and then snapped at me.

I don’t want to be scared of her so I obviously want to stop this behaviour. I get that she is probably just being a moody puppy and her intention was not to hurt anyone but I don’t want her to keep doing it. Maybe as she gets used to being outside at night she won’t put up a fight, I just don’t want this aggression translating to other scenarios when she doesn’t feel like doing something I’ve asked. I have never experienced this with a dog before so that’s why I need advice on how to train her.

Any advice would be greatly appreciated. Thank you all.
