My Dog's Unusual Habit

Well, this post doesn't really have anything to do with what has happened this week, but of a thought that randomly popped into my head. One of my dogs, a miniature Pinscher named Mia, has an unusual habit. she likes to rub her body on dead animals ( yea I know, EWW!). When I first saw her do this, I thought she was just a weird dog with a disgusting habit. Then, one day, my sister's boyfriend went online and looked up my dog's unusual habit, and found that it really wasn't that unusual.
Turns out, that many scientist believe that dogs will rub their bodies on anything with a strong scent, such as dead animals, manure, and garbage, as a way to cover up their scent. This instinct comes from their wolf origins, to be able to sneak up on their prey without being noticed. Another theory many scientist believe is that dogs will do this to show their pack that they have found something. After rubbing their bodies on something, dogs may run back to their pack where they can all together, return to the object. The third theory to dogs rubbing themselves on dead animals is that they are trying to leave their scent on the object or cover up the previous scent.
