Springer Spaniel Suddely peeing in crate

by Jill
(Berkshire)

We have a 14 week old Springer puppy who has suddenly started peeing in her crate after 6 weeks of not doing this? She tends to fall asleep at around 7 pm and thus we've put her to bed and not heard from her until 6 am which seems a rather long time (although we are glad of the peace in the evening rightly or wrongly!). She's never had a mistake in the crate. However she does pee when I or other members of the family leave the room, even if someone is left in the room - there's a stairgate so she can see and hear the person leaving the room? The smell is quite overwhelming today - very strong - sadly its right through her bed so I think perhaps its going to have to go in the bin otherwise it will always smell (foam filled cushion type) - I've gone back to vetbed which I can wash but not certain you can ever get rid of the smell once its there? I clean the crate out with bicarb and hot water.

Any suggestions please would be greatly appreciated.
