My 5 year old pug poops on beds/couches
I have a 5 year old pug. I got him as a puppy, and he was immediately put through potty training. He mostly does great, and goes out regularly, as I work from home. So, this issue isn't because he has to hold it too long, and is then going in the house. He very much does this on purpose.
He will withhold poop outside, or just go a little. Then, inside, he will deliberately sneak off into one of the bedrooms to do this. He especially likes my daughter's bed, as it's lower and easier for him to jump onto. He will even push himself into closed doors enough that they open, so he can get into rooms where I've closed the door.
In talking to the woman we got him from, she said she kept them in pack-n-plays in her living room, with blankets over potty pads, and they just peed right in there and she washed the blankets and replaced the potty pads. I think he's always enjoyed going on blankets ever since and he seems to seek it out.
Short of getting better doorknobs or locking the doors, has anyone else dealt with this and gotten their dog to stop?
