We have 2 puppies that I'm trying to pad train. They are 3 months old and when we brought them home a few weeks ago we were told they were pretty much pad trained. One puppy does pretty good going on the pad or at least having 2 feet on the pad about 90% of the time. The other puppy barely uses the pads just goes where she is standing. Outside training I know how to do...have trained a few puppies to go out no problem. However due to the fact that both puppies are only 6 lbs and barely 8 inches tall going outside where we probably still have 6 inches of snow in our yard and bitter temps it's almost impossible to outside train them. I am at a loss as to how to convince the 1 puppy to use the pads. On the rare occasions when she does use the pad we give her plenty of praise and a few treats. Any advice will be so appreciated!! Thanks
