I found out another dog fact the other day - precipitated by the fact that whenever my dog finds poo (in this case duck poo) she loves to roll in it. Apparently it pre-dates back to an older instinct potentially from the wolf where rolling in the fecal matter of another creature would potentially mask the dogs scent from capturing its intended prey. Who knew that my duck poo rolling 13yr old maltese pooch with NO teeth with masking her scent from her intended prey, which grossly turns out to be my work shoes when i get home and take them off. She likes to be AFFECTIONATE to them, perhaps Ive said too much lol
