Foolish dog is 8-9 ish with no known health issues. She has always had a cast iron bladder.....
suddenly she is "forgetting" to wee in the garden (never her favourite...she prefers to wee away from home, and would certainly never poop on her own grass 
) even though she asks to be let out.... she comes back in 20 minutes later and just sort of "leaks" small puddles. If i take her out on a lead she will wee a bucket full so I think it is "overflow".
She is otherwise always totally dry overnight and all day the puddles happen after we have done a big walk/off lead run and she is tired and a little stiff when these accidents happen. Also more frequent in really hot weather when she drinks more.
Any one had any experience of this? Any ideas?
