The easiest way to answer this question is to trade places with your pooch. As a social pack animal, you consider it your job to guard your territory and look after the rest of your pack (in your case, the humans you live with). Feeling at home in Fido’s fur? Good. Now consider this: Nearly every day, a strange human approaches your territory, often while the rest of your pack isn’t home. It’s an intruder! The stranger rattles the front door, trying to get in. You must protect the house! You bark and growl and leap against the door, doing everything in your power to scare away the intruder. And it works! The stranger wanders away to the next house. Mission accomplished…until tomorrow.
