They can adjust. I had a toy poodle for a long time. As he got older he started to mark all over the house. Drove me insane! What we did was get a very large dog crate and set him up in that. This gave him room to pee if he needed to but also room to get away from it. He was probably 7 years old or so when we started that. Up until then he had free run of the house with a doggy door to the backyard. He adjusted to the crate just fine though. I hope you have as much luck as we did.
