i was taught that a dog can hold its water one hour for every month of age. a four month old then,should be able to wait for four hours between walks. Crate training is great too. there are some good books on training--I have an 8 year old and a 10 year old so it's been a while. Plus, they're both rescues so came to me a little older. My 10yo was 7 months and had no clue about training. I'd walk her for 2 hours and she would come in and then pee. it took me going psycho on her to convince her to pee outside--literally. I think she had never heard anyone yell, much less go berserk! since then, no accidents! the 8 year old was much easier. We got her at four and with her history, she barely peed at all--I had an animal communicator to help. Neither has accidents now unless ill. OF course, always on the carpetted area not the tile-
ah well, they give so much more than the work they require it's all good
