some people on here have had sucess doing both. I however, did not.
Tucker started out pee pad trained at the breeders, so I tried it at home. He was the first dog that we tried using the pads with. Didnt work. He did great for the first few weeks, then he started going all over my house so when he was almost 4 months old, I started taking him outside. It was alot of work and alot of accidents but at 6 months old, he started going to the door on his own and at 7 months old he is completely trained and hasnt had an accident in the house in over a month. Which ever you decided to choose be consistant, use lots of praise and treats!! Good luck!!
