OMG! He's so cute! I am laughing so hard seeing your pics.. seriously, I wanna hug him!
He's a very good boy being able to stand still and posed for the pics. I remembered when I put a raincoat on my dog and we were laughing so hard seeing him on it, he instantly realized that he looked funny and just won't move. I had to dragged him to the door for our walk on the rain.
Btw, is that your cat standing next to the dog?
\Awww they are both gorgeous! Dont suppose you got the cat into costume tho?
