Our alpha cat Stumpy has always loved dogs, and grieved with the loss of each one over the years. When we adopted our 2 puppies last year, he was in heaven, and spent a good part of the last year training them to be his new "toys". Here is a picture we took of him the other night with Sam (now about 13 months old) - he loves to go up to the dogs and rub all over them. He sometimes will fling himself on his back between their legs and engage them by whapping at their faces. The dogs oblige back by licking or nibbling on him. I love to see dogs and cats interact like this!
