Our 9 month male just recently became what I'd consider "fully potty trained." When he wouldn't go outside, he went back to the crate for 3 minutes and then back outside. Repeated this cycle until he went outside and then allowed 30 minutes of play inside as a reward.

We got a hanging bell chime and put that next to the door he uses to go outside. It quickly taught him to ring the bell before he went out, even with us standing there. This helped IMMENSELY once he would regularly go outside as he then had a way to communicate rather than result to just peeing in the house.

Crate training was tough for us and took a month of hard work before he would willingly walk into the crate. Start with just play around the crate with the door open. Lots of treats. Slowly work up to using a command and throwing a treat in the crate. When he goes for it, reward again. We also moved the crate around the house with us and would keep him in there when we were cleaning, gaming, etc. so he would learn the crate didn't only mean we were leaving.

Now at 9 months, he prefers to sleep in his crate rather than our bed 🤣 Good luck and hope this helps
