They do the absolute cutest thing. Einstein (my boxer-lab) will lay down, and Danger (my yorkie) will cuddle up next to his belly. It is SO HARD to get a good picture of it because I never have my phone or camera next to me on the couch when they do this and if I move, they both get up and follow me. lol
But this was the best picture i was able to get of them on my phone. Unfortunately it wasn't them snuggled up together, just laying next to each other. But still cute.
I also attached another pic so you can see their faces.
