My 11 month old dog was using the dog door to potty outside but after a camping trip and weather changing he now goes to the bathroom inside. How do we let him know it's not ok to potty in the house?

This is a very common issue with dogs that are not 100% potty trained and actually I get a lot of messages similar to this when the seasons turn to cooler, wetter or snowy weather.

Some dogs don't mind rain or colder weather, others require you to go outside with them so you know they have used the bathroom outside. I don't use dog doors for my dogs but we do have indoor/outdoor runs with dog doors that some of our previous dogs used. His foundation of being in a shelter set him up to potty when he felt like it so my advice would be to confine him when you can't be sure he's gone to the bathroom outside. Use a crate or puppy pen of some sort and make sure he actually goes outside. It's a bit more work for humans when dogs come to us with these habits but if you manage and supervise him and prevent him from having access to using the inside of your home as a bathroom you should be able to get back on track.

Same with jumping, I'd supervise him and spend some time teaching him an alternate behavior (like sit) when he wants interaction with you. I'll link some helpful resources for you below. The course from the Rescue to the Home is a free course.
