My dog that is a carin terrier/westie mix and he was house trained when he was about a 8 1/2 months old. He’s now 4 and has started peeing everywhere! I find the stains and clean it up and scold him when I catch him in the act but he still continues it. I don’t know how to stop him from peeing everywhere and its been going on for a while now and my house is starting to smell bad in some places. Is there a solution to re-train him and to get the smell out?
