Help! We have a new puppy in a crate and for the last four weeks it mess all over, the poor pup every morning has to bath and then I scrub the create! Every single morning. I wake to the terrible smell as I walk down the stairs! I have another dog who sleeps in a bed next to the crate, could that cause a problem? Also she some times just gos in the crate and does a wee even when the back door is open...... Any tips anyone PLEASE!!!

How old is the pup?
Do you get up in the night to let them out to go toilet?

If the pup is still very young then it wont be able to last all nite without having to go toilet. Suggest you put pup out for pee/poo just before going to bed and then get up a few hours later and take them outside again. maybe twice a night to start and then down to once and eventually when they are old enough ( gained bladder/bowel control)they will be able to go all night. :)

clean the crate with a biological washing powder to remove all traces of pee/poo, as any trace of smell will just attract the pup back to toilet there again.
