The way that your dog waits for you sounds really adorable 
My older cat isn't very cuddly, but when she wants a petting she lets out a really cute sound and rolls on her back showing her belly. If I don't respond right away, she'll continue rolling from side to side along with making the same sound. It's the cutest thing she does.
My younger cat, on the other hand, is extremely cuddly, and he's very open about it. When I don't come down to his level to pet him, he'll try to climb to my level and put his paws on my shoulder like a hug. Sometimes he'll even try to place his back legs on me too so that I would carry him while I pet him.
