not sure how this forum works, but it won't let my replies go thru immediately? Anyway. I appreciate all the input. I just cannot live w/a dog that is not potty trained. OTOH. It is only 15wks in. I just know how hard it is to undo unwanted behavior. The tethering is a great idea. I've done it before. I'm scared I'll step on him (done it several times already-Yikes). Never had a pup this small (or cute). I will definitely be using belly bands when I visit family, but am hoping thats the only time I will need them.
I know I sound harsh and impatient. I'm getting up in age and it's been a long time since I've been this challenged w/potty training. I AM SO TIRED!!

With other dogs in the house, I run the risk of them regressing also.
The puppy "apartment" is also a great idea. I have 3 ways to go w/that but haven't decided the best way. I have a 4ft x 3ft metal crate, the Northgate superyard
Amazon.com: North States Superyard Play Yard,... , and the 46" soft-sided octagon playpen
Amazon.com: Pet Gear Travel Lite Octagon Pet Pen... I hesitate to use the latter as he urinates on everything. Realized this morning that he tagged my winter jacket that was on the sofa! I don't want him to get used to urinating on it as I was hoping that would be his adult condo when I'm not at home. Whenever I leave him alone w/pee pads, he tries to make confetti. So I'm not convinced lining it w/pee pads will work. Any ideas would b appreciated.
It amazes me how someone so little can get into so much! One thing I've decided for sure, I need to stock up on red wine and work on relaxing and enjoying this guy. Lol.
Thank you all. Every comment gives me more to consider and strength to soldier on!
