We have an 8 year old Maltese x shihtzu. He's always been toilet trained. We have another dog 2 years younger with no toilet issues. Set up is we have a dog door, a verandah, lawn and bark chip area.
For the last 18 months (going to call him Woof because my phone keeps autocorrecting) Woof has been toileting inside any chance he gets. We've taken him to 3 different vets for opinions as we were worried about something being medically wrong with him. However they've all said Woof is fine and the advice has been to retrain him like a puppy and check if there's anything outside that scares him.
We've lived in the same house for 8 years so no big changes. Nothing outside that I can see that frightens him. I've taken him out like they said to the toilet, praised him etc. Mostly it happens when the weather cools down. He doesn't like it cold outside and he doesn't like damp ground.
We've set up an area right next to the door so he doesn't have to go out into the cold far. But this morning he's still gone and peed on the carpet. I've had the carpet professionally cleaned more times than I can count now.
Dogs get walked twice during the day. Woof gets carried the way back because he's smaller than Big Woof and can't go as far.
Any suggestions?!
