Does anyone have any experience of a previously house trained dog starting to pee in the house? She has started to do it for the first time about 3 weeks ago, and when I think about it, it only really happens at the weekend? At first it was a dribble but now it is quite a bit and sometimes just after walks that she has been peeing on????
We have had the vet check her over, and test her urine - all seems fine.
Now if I am honest I am afraid this is my fault she used to be my precious baby (until I had a baby 21 months ago). Now bless her her gets little attention from me in the day, except to get told to get on her bed when I am feeding DD. Up until we moved house 6 months ago she used to go to a dog sitter in the day and be with other dogs, now she stays with me most days.
Do u think she is unhappy because of me as I never have any time for her?
I think it's unlikely that she's upset about her diet, but dogs can very quickly learn that if they do X (eg peeing in the house) then Y happens (eg DH giving her a cuddle, as you say). You have to completely ignore the unwanted behaviour (except perhaps to usher her outside when she's weed indoors) and make sure she only gets attention when she's behaving the way you want her to.
Might also be worthwhile teaching her to wee on command outside (as she starts to wee, say 'be clean' or whatever, and give her a treat then & there). My 10 yr old (not terribly bright) dog learned this recently so a 4 yr old lab should walk it!
