I am not particularly fond of owning dogs and for that matter any pet purely from a laziness perspective. It is quite a dog's work (no offence meant for the dogs) to take care of them, keep them clean and to keep the house clean.
But if you think of all the famous characters in cartoons, books or movies you are fond of, most likely some of them will own dogs. Some of my favorite dogs are below.
Hotdog - Jughead
Hutch Dog - Hutch Ads (The Network follows where you go)
Ruff - Dennis The Menace
Pluto - Disney Cartoons
Snowy - Tintin
My dream house definitely has a cosy kennel under a tree with the name board of my dog "Einstein" (not as an offence, but more out of great respect for the great guy).
