Hi,
My Grandmas beagle eats hers and other dogs poo. My mum looks after her when my grandma goes out on a saturday or sunday and I was over there, we were nattering in the dining room and noticed in horror she was eating what one of my mums border collies was doing as it was being produced!!
She does have a ravenous appetite and is on a diet so I thought it may be down to lacking something in her diet. Interesting about the pro biotic as i always keep some powder in the cuboard for my dogs may get my grandma to try it. Oh yes even though you clear up all the time it's when you go on walks thats a bit more difficult!
