Dylan regularly eats other dogs' poop when out and about.
He used to eat his own when he was little, but we managed to get him over that. But however hard we try - he still manages to sniff out poop when we take him out - whatever we do to try to deter him - he's a determined little wotsit.
He also likes snails (including the shells) and vomit (his own, his sister's or any he finds out and about)
He hasn't had the opportunity to get some of the other horrible things I have heard they can like, but I'm sure given the chance he would tuck in
Unfortunately, his little sister Daisy is now taking an interest in anything Dylan gets hold of
