My puppy doesn't touch his own poo, but loves to dig up the cats poo and eats it. I'm thinking it maybe a territorial thing as he poos where he's dug up and eaten the cat's. Anyway, I've started following him around with a bottle of spray'n wipe type cleaner (all I have handy at the mo) and as he digs up the poo I spray it and he won't eat it. It's probably not a permanent solution as I'm sure once we start leaving him outside alone he'll go at it again, but he is spending less and less time digging and eating. That spray cleaner is great stuff for keeping him away from things I don't want munched (eg. electrical cords ).
