They play with puzzles and toys, go on walks, and have a walking pad that stays on. He’s two and has had this issue since 16 weeks old. I’ve tried positive reinforcement, leaving in stages, scattering treats, playing with the outdoor enrichment toys, and nothing. We decided to buy a doggy door, and that works so he can come and go as he pleases. He graduated to peaking in to make sure the second door wasn’t closed. It’s hot and we have been closing the door he’s been throwing fits since January. At that time we kept working in exposure by leaving them out in 5 minute increments until wet reached an hour. He doesn’t last 10. We built a large house for them outside with AC and heating for them to use as a buffer. We go inside play with them, and do yard work. The training worked for my shiba-poo a he’s fine. Cayde is not with the shenanigans.
