My dog Luca loves to roll around on top of dead animals.

Take for example the days we walk along the waterway where a bunch of fishers have been spending the day.

Luca will sniff out the residue and if she's lucky she'll spot some dead fish which has been gutted and whose bones and scales have been left their in the sun to rot away.

Before I notice and can do anything about it, there she is rolling around upside down on top of the dead fish rubbing her back into it with much delight and wiggling.

The problem is that even though I wash her down when we get back home, the house stinks like a dead fish for a couple days.

They claim that this is normal dog behavior, a kind of instinct or throwback from the early days of wild dogs before they were domesticated. In order to survive, they would need to stalk and kill prey. In order to hide their own scent, they would roll around in many disgusting substances so that they could approach their prey undetected.

This sound kind of silly and I'm not so sure I believe it.
