Where does your dog go to do his business? I know it may be a silly question since most people would say outside, but since yorkies are small dogs, my puppy uses the wee wee pads. And since where I live it gets really cold in the winter and this entire season I've only been seeing snow on the floor like seriously everyday, I find the wee wee pads easier. He's been using them fine so far. But honestly, is allowing him to use that bathroom outside better? What do you guys think the pros and cons are of wee pads and outside training? Thanksss
