hi i have a blenhiem cavalier she is two and half and ive noticed her back legs seem a bit weaker than they should be......like when youve been stood for ages and your legs go a bit wobbly? also i have wooden floors and shes forever sliding about and slipping could it just be that or sumthing more serious?

with the problems in this breed at the moment I would get this checked out , when you mean weak do you mean has trouble standing or walking ? is there any pain at all ??
