Why do male dogs lift their legs
on your favorite shrub?

Some of the most irritating conducts dogs have are their strange sense of humor and sometimes weird personality, as well as being extremely zealous. In that sense we can understand why they act the way they do. It's like saying "Hey dude, if you're going to take care of that bush better than me, I'm going to take care of it too, but my way!"

Evidently, dogs don't pee only because of nature's urgent calls, but because they feel they're being left out. In this case, they start to act as little spoilt brats doing things they usually wouldn't do. All this only to call one's attention. That could be one of the reasons why they lift their legs on other people and plants as well.
