My dog is a lab mix with Beagle, he's approximately 11 years old always when outside to use the bathroom.. We went on a cruise for seven days someone was also stay here with him to let him go outside but I don't know what happened or why he started , and pee on the floor I'm not sure if this person scared him or he tried to tell her he needs to go the bathroom in the middle of night and she told him to get away.. I'm not sure what happened now that we are back I have tried cutting back on his foods and is water and having him to go outside often to go to bathroom.. Somehow in the night he goes and potties on the carpet... I'm just sure I'm not sure how I can help breaking from this.. I'm trying to give him a few weeks figure out ways to help them otherwise I might have put them down.
