Hi Can anyone help. I have a blue staffordshire terrier longlegged long nose,she is 4yrs 9 months old, just recently she has started to wee indoors instead of outdoors, has anyone got any suggestions as to what is causing this?

The first thing to think about is a urine infection.  Catch a clean specimen of urine and pop it into the vets.
Has she been spayed?  Some spayed bitches become incontinent at times but I would have her urine checked first of all.

She could also be coming into season I find mine do this at times near their seasons.
