Why do we love dogs?

I got new pillows for the couch since are old ones were very old and had lost a lot of fluff. I thought I would be nice and give the dogs the old ones since they love to lay on pillows. This is my thanks! Yes they are still alive and yes it is an old pillow note why they are still alive. I do want to point out a few things #1 both dog are not in the picture they are both hiding already when they heard me coming. #2 I'm not sure if you can see it but there are Molly toys on the floor and some of my pumpkin decorations not touched. They must enjoy living. Honestly I laughed saying you stupid dogs it was your pillow now it is gone. Why do we love dogs?
