I have two 3 year old yorkies... I move with. By BF and now they seemed to have forgotten their training.

They were crate trained... They sleep together. Their previous home they were let out to potty in the morning and throughout the day. We made sure to take them out before bed time. They have food and water available to them outside. They were completely potty trained. I also had a doggie door for them to go outside.
Now it's been six months and getting bad. We stuck to the same routine but now the pups will go outside and take forever to do their business... Then we let them in and they pee in the crate and sometimes jUst outside it!! I am at my wits end....should I try wee wee wraps when they are inside? Or put them in separate crates? Any tips would be appreciated.
