He is cute, i have never rubbed my dogs nose in accidents. They all have em, i find buying a bell and hanging it on the door and ringing it when you are on you way out for a pee with your pup helps. Also chanting pee peeees outside
, whn my guy was very little i took him out every 20 minutes and 10 after he drank. When he went to the bathroom outside he got a big vocal "good boy you pee pees outside", when i caught him mid squat i promptly picked him up gave him a stern no and ran him out to the yard. What worked for me may not work for everybody though
congrats on your pup!
