One Smart Dog!

So my aunt lives down the road from me and I am babysitting her two little boys for the night.. We'll she has a dog named Ivy and she left her at home.. So as me and the two boys are asleep in the living room, the oldest boy and I wake up I hearing what sounds like someone kicking in the back door! So we call my cousin downstairs to go check it out.. It was IVY!! It's like she knew that the boys were here she ate a hole in the door trying to get in!! I tried keepin her in the laundry room but she insisted on coming in! I let her in and by this time both boys were back in the recliners asleep she come in and I tell her to lay down( she lisstens) we'll a few seconds later she's looking all around the room she gets up climbs halfway up each recliner and checks on the boys and I tell her to lay down and point at the floor and she growled at me!! I guess she scenced that my aunt wasn't there to protect the boys so she felt she needed too! But I've never seen her ac like this! So strange! But seriously thought I had to share!! Dogs have a heart too!
