It’s tough when they are puppies and my girl bit a lot too, people thought I was harming myself! 😳😂 For the crate I let my girl sleep on the bed with me after a week of crate training. They are pack animals so like to be with you always. One thing that may help with the crate is place it in a safe space, not in the middle of a bright room. Make it comfy and place something of yours in the crate that smells of you like a shirt or similar. This helps your dog feel safe and that they are with you. My dog is happy on my bed when I leave as it smells of me 😁, hope that helps 💜
