I have a 5 year old greyhound. I’ve had him for almost 3 years, and when we adopted him he was already house trained. He never had any problems with doing his business outside, i was actually surprised for how long he could hold it sometimes. Anyway the last three days, he’s been having problems. He has gone to the bathroom the last three days in a row in the house, and he wasn’t even home alone for the first time. The two other times we only left the house for about an hour. We even let him out shortly before we leave.
This is very out of character for him, so does anyone have an idea about why my dog is suddenly going to the bathroom in the house?
