What have you tried that isnt working ?
Its really all about timing, take the puppy outside first thing in the morning, after food, and other times you are noticing it needs to go.
Basically you need to take it outside a lot, and praise it every time it goes out side.
I live in a tied cottage, so trying to decide what to do for the future, love the job and house, but now with 3 boys, thinking a lot more about the future than i ever have before, and need some bricks, mortar and land of my own.
