Buster is a little over a year old and he's finally getting pretty reliable. Maybe one accident every few days.
For the longest time, he'd get probably 80% of his functions on a pad, and one accident a day, sometimes while he was looking right at us.
He has been surprisingly difficult to train despite pretty consistent efforts from us, but he's getting the hang of things. Every once in a while, though, he'll have a span of a couple of days where either his housebreaking or obedience training go completely out the window before he behaves again for a month or so.

We love him, but man he can be frustrating!
