Max use to roll in cat poo, until I scolded him by rubbing his nose in cat poo & tapping his nose & fermly saing no, yucky poo poo. Saying yucky poo poo will make him stop in his tracks & spit out or flee what ever hes sniffing.

My dad will not bath Max, only cause Max wont get in the tub for him & he fears the water will be too warm or too cold, & doesn't want to hurt Max. Soooo dad put ketchup on him to hide the cat poo smell until I get hime... hehehh u think cat poo is gross, well add ketchup & its even grosser

But for dead things Max doesn't rool in it, he will point & sniff.. its quite funny, hes not even a pointer & he does a fairly good job of pointing.
