Why do dogs roll in fox excrement?

Answer 1

To mask their canine scent, in order to sneak up on a fox to hunt it.

Answer 2

In the wild, as wolves would do, they would roll in new smells and then take it back to their pack to investigate it. They roll in it because it is an unknown smell to the dog.

Answer 3

they think its cologne or perfume, no joke. my dog does it all the time, and they like the smell.

Answer 4

Because foxes don't get on well and will attack each other so they will smell it and will want to hunt it to kill it.
