Hi, I have an almost 4-month old maltese and I need advice on which is the better way for me to use to potty trained my dog. It is better to paper train indoors or teach dog to potty/pee outside. I live in the northeast so I have Winter (snow) to worry about. I started potty training for a few days and then had to stop because its has been raining hard the last few days. Now my puppy is a confused and has been having accidents all over the place. I want to switch to paper training so he knows where to go indoors. Do you have any tips on paper training ?
