Please help me! I have a 5 year old dog that has started to pee inside. I’ve had him since he was 7 weeks old, and he’s been house trained since he was a little puppy. He spends the day outside and comes in at night. For the last 3 nights in a row as soon as I bring him in he pees on my kitchen island, and I mean immediately. He literally is outside ALL DAY LONG, I don’t know why he would start doing this.
