Jealousy

You would think that jealousy is a human emotion, but I have learned that dogs and cats get really jealous.  I didn't realize it until May of last year.  We got a pug - Dobby.  He had lived with other dogs and cats, but the girl we got him from didn't mention he tended to be territorial.  Well, he is.  When we got him, he was instantly MINE.  He decided he was my dog and I was his human.  Period, end of story.  So, when I would pet Draco, or either of the cats, he would bark at them.  And speaking of, he still does it!  James was playing tug with Draco tonight and Dobby kept barking his silly weird bark at them.  It's funny, but also sort of annoying.  It causes fights between the dogs, which I HATE!  And I noticed yesterday that Draco has jealous tendencies now too!  Dobby was laying in his bed right next to my desk and he looked so cute that I started rubbing his ears.  As soon as I did that, Draco came over and started moving my arm away with his nose.  We have 4 animals and they all tend to be mommy-centric.  Wherever I go, they go.  I AM NEVER ALONE!  Even when I go into the bathroom and shut the door, I get one or more of them pushing on the door to try to get in, or I get a cat paw under the door.  Ahhh, come on!
