I know everyone loves to give training advice whether they know what they're talking about or not, but if you don't listen to any other advice listen to this. No matter what method you choose for training, enforce your commands. Give them one time and make the dog listen. I see all the time...
As long as she knows it isn't owed to her and she's not allowed up unless you give her permission she'll be fine. Avery always "asks" before I let her up, she puts her head on my bed and sits. If I tell her no thought she knows that's it and she'll go curl up on her rug.
She'd never get up on...
I always slept with Avery. She's never had any issues. Though labs aren't real territorial dogs, lol. She's good with whatever. Whether she's in the kennel or inside with me. I do love sleeping with her though, it's so comforting. Especially after a rough day or on a cold winter night. 🥰
Yeah I would not do treat training. It can work on a very small puppy to get them to enjoy learning, but it creates a food driven dog that is more prone to becoming food aggressive (a very common problem in herding breeds and not a good one to encourage on purpose).
And if you don't have a treat...
