I cant remember who but someone once told me that if you give your dog crushed pineapple either by itself or in its food it wont eat cat poo anymore because the cat's poo no longer tastes appealing to the dog
dont know how accurate this is, i myself have never tired it as i thought pineapple might be too acidic for dogs?
hmm maybe google it, im sure there are ways on there that might help?
My Amstaffs do the same thing, we have a cats room and they always try and run in there first thing when they come in the house and eat the cats poo and then the cats food, amazing its not the food first but anyway....
If you find any ways, please do let us know, i know i would be keen to try it too
