I have a 1 1/2 yr old Cavalier King Charles Spaniel, who is the most adorable. He is potty trained though not completely reliable. He won't mess on my main level however he will go to the basement and do his job. For the most part he goes to the door and sits down or scratches the door to be let out. I feed him just twice a day. Also if I leave him at a friends place for a few days, he pees and poops in their home constantly. I have had him since was 8 weeks, he is neutered and has no other issues. How can I get to a point where I can give him free reign of the house. I am also embarrassed to leave him with anyone.
