Hi....Have you tried pee pads?...I use them held by a plastic frame so Teddi doesnt tear or pull them....I know it would be ideal for our dogs to toilet outside, but the pee pads work a treat for me and keep the house clean....I had to remove my lovely shag rug from the living room 'cause Teddi loved to wee on it....I know how frustrated you must be feeling right now and your dog has left his scent at all the places he has used....I know people here on YT will give you more information about crating.....hope you find a solution....
