Adding to my last question: If I soak cats' faeces in tabasco or a strong chili sauce and leave it lying around in the garden or sand box, do you think that will do the trick?!!
I think MY dog would probably like that a lot!
Have you tried scent-off type things from the pet shop or orange peel? There are some smells dogs don't like.Maybe get rid of the sand box?
Why did you post this as a new question instead of continuing with the original one, it gets confusing when you need to look up the original question in order to answer this one.
I was told pineapple juice or cooked aubergines but that might be for dogs eating dog pooh, We have the same problem in this household, The only way I can definately stop the dog's from eating it is to get up early and clear the cat pooh from the garden before the dogs get up.
