HELP! I have 3 chi's and they are brilliant dogs apart from one problem.....i cant seem to stop one of them going to the toilet in the night! She is now 3 yrs old and has done this on and off throughout her life. Its only ever during the night when im asleep. I also have a 1 year old that has been clean and dry from day one and a four month old that is brilliant. Obviously he has the odd accident but hes learning fast. Luckily the 1 year old didnt copy her, so im hoping he wont. Ive moved in with my boyfriend recently and hes never had a dog so no smell, but shes doing it here too which is embarressing, even though hes not worried. What drives me mad is that they are all clean during the day wether im here or not and some nights so i know she can hold it. I feed them early eve, walk them and let them in garden loads. It makes me mad as some eve's we go to bed at 11.30 and get up at 5 and shes done it...ggrrrrr...any help appreciated.

try puttng the alarm on for around 2.30 / 3am go down put her out give her time to go but dont interact with her then put her back to bed . Sometimes this works for a slow learner puppy not sure about the older dog! worth the inconvenience if it works but dont expect miracles it will take a bit of time .

Have you cleaned the place she goes really well? just in case she can still smell it and that makes her want to go their again.
Also when did this start or has she gone backwards in the last few months? just thinking she maybe scent marking because of the younger dogs you've now got.
my newest dog kept having a wee on their bed at night and i'm sure she was trying to mark her patch because of the other dogs. thankfully she has stopped this now but i did have to throw the bed out and now i use blankets that can easily go in the washing machine so i know they've been cleaned really well.
Maybe worth a phone call to the vets just to make sure there's no other problem, although if she's fine in the day you'd think she was ok.
how often do you let them out in the day? if you let her out to often maybe she's not learning to hold on to it for longer periods of time.
this could also be a habit by now and you may have to follow the advice given about getting up in the night and see if this breaks the habbit.
let us know how you get on.  

if all checks out ok at the vets I would crate her at night, dogs dont generally soil there own bed so she will ask if she needs to go out.  I used to look after my friends cockers who would pee every night without fail so I crated them - they never asked to go out and never soiled their bed either, it was a habit they had got into.

>dogs dont generally soil there own bed so she will ask if she needs to go out.

That's fine as long as you're within earshot and a light enough sleeper to wake and let her out when she asks.

well that goes without saying ..

It should, but you'd be surprised at the number of people who think that simply shutting a puppy in a crate somehow magically means that it won't need to relieve itself, and leave it confined in the kitchen whilst they snore away upstairs. Then they're surprised and angry that the 'naughty' puppy has soiled its crate in the night ...

Buster was a nightmare to housetrain, he started to get it, then started to wee in his bed (not crated), whilst he was sleeping and slept in the wetness, stinky little monkey! (vet-checked, he was fine ).

I trained Bust on paper, something I wont do again, as all it taught him was it's OK to wee on things. I've got fed up of cleaning the huge rug in the livingroom (his fave 'wee-pad') and chucked it out 2 months ago, as he was still weeing on it during the night (he's coming up 2 years old and Mastiff 'puddles' are more like 'lakes' ). For a week or 2 after the rug was removed he had an occasional widdle in the hallyway (on laminate flooring, easy to clean :) ), then he appears to have stopped weeing in the house during the night & touch wood, we've had no accidents for a few weeks :-)
Prior to removing the rug, I had started to lay an old shower-curtain over it (thinking it woul dbe easier to clean than the rug), it actaully stopped him weeing on the rug, untill I would forget to put it on one night, & he'd wee on the rug again. I thought he would never be dry at night and he is now, all it took was removing the rug to break the habbit :-)
You could try putting something water-proof down in the place she normally wees, you never know, it may be enough to stop the habbit, if it isn't at least it's easier to clean up the piddle ?

Thankyou for all your suggestions :) Its something shes always done since ive had her. I often wondered weather its because shes very dominent. She has regular vet checks and had beautiful pups last year so dont seem to be anything wrong, as i said she will hold it in all day and most nights. She also always asks to go out when im here. Its not even because the pup has a pee pad as she will do it on bare laminate...before i had the pup...lol. Ive never crated any of them but seeing my boyfriend having to tip toe around puddles and poo 5am is getting me thinking i should. I  think if i gradually get them used to a crate it might work out for the best. Its lovely to hear all your suggestions :)
