In my experience, a 4 month old pup can't hold it that long...8 hours is a long time- The first time Dillon was able to hold it 8 hours was when he was about 7 months old- He has access to me all day to let me know he has to go, and he has a bell to ring when he does have to really go...I think it is best if you can have someone take the pup out after about 4 or 5 hours even if it is just to go potty and play for a few minutes. A pet sitter...or maybe even letting the pup go to a puppy daycare a few days a week. Just a few ideas..
