My lovely lab is 13 years old. We've had her for 3 years (rspca) and since I've had her I've noticed if she was to eat any diary then she wet farts so we strictly avoid that! But for the past few weeks she leaves a poo smear when she gets up, it happens everyday no matter what food she eats. Is it an age thing? We have a little baby who's not yet crawling but I'm dreading him crawling in anything like that and I try and check everywhere she's been to clean up possible marks.
