My little susie keeps going to my cats litter tray and taking poo out and eating it its discusting any ideas how i can stop her from doing this

they eat their own poo or others poo because they are not getting the correct nutrients. Dogs get nutrients first time round BUT they have a lot that it not absorbed into the body and they can still smell the food when they go to the toilet. This is the reason for eating it again. Try changing food or adding some treets into suzies diet to keep her nutrients up. It does have a name but i cant remember what it is grrr if it comes to me i will let you know. Hope this helps.
You could also get an enclosed cat litter tray so that the pooch cant be tempted.

Almost all puppies eat poo, their own and that of other animals, the best way that I have found of stopping it is never to let them be in the situation where they can get it really, train it out of the little darlings :hihi:

Try giving your puppy pineapples chunks, failing that there is some tablets u can give them to stop it. If you want the name of the tablets i can find them for you.

Like Moonbird has said try removing as quick as possible,

Put some mustard on it :hihi:
