Patience, they are EXTREMELY STUBBORN AS PUPPIES...I trained mines to go on the wee wee pad and I remember getting home from work at 7am, taking her out the crate and sitting with her in my bathroom with a wee wee pad
Same.
We wanted our Frenchie to go outside in our patio, so we started with a Large Pee Pad that we had next to the door. Surprisingly, we never used treats to potty train him. *shrugs*
I have 2 daughters so they helped
A LOT. Potty training was literally like watching a newborn baby. You really couldn't take your eyes off him unless he was eating/laying down/sleeping.
So any time he had an accident, we'd plop him right on the pad immediately.
then it got to a point where if we noticed him squat, we'd yell "NO" to somewhat stall him, then pick him up and drop him on the pee pad and after a few minutes (or so) he'd go.
once he got used to the pad, we finally removed it and anytime he'd to go that spot we'd just open the door and he'd go right outside.
Now, what he'll do is go to the sliding door and just stand there looking back at us to open it.

If we're lazy, we'll wait for him to knock on the door. That's usually our cue to open the door for him.
