I have 2 lakeland terriers, at the age of 1 and 2,and im having alot of trouble trying to get to do there business outside. Every morning when i get up i find a poo and wee and they will just not hold it in for when i let them out in a morning, how can i prevent this from happening as i live in a flat and can not keep up with cleaning there mess behind them. HELP PLEASE!!

well first thing is do not let them have anything to drink before they go to sleep and do not leave water in a bowl so they can get to it feed and water them in the evening then dont let them have anything else also put down newspaper where they sleep and they should get the idea to do it there it is harder to house train when you live in a flat

If they poo and pee in your flat at other times I would start housetraining from the beginning.

If they are clean except for overnight you may expecting them to hold out for longer than they are physically able.  If one reaches the end of their staying power and poos or pees before you can get them outside in the morning, the other is likely to do the same.
