You are possibly the most ignorant person I have ever seen on deviantART.
Do you have any idea how beneficial dogs are? They are a tool.
There are K-9 police dogs and military dogs. There are seeing eye dogs, therapy dogs, search and rescue dogs. You can use dogs for hunting, obediance, bomb/drug-sniffing, herding cattle and sheep, and showmanship. Dogs excel at agility, racing, and dogsledding. Not to mention that many dogs are trained to kill rats and mice, which are overpopulated and carry diseases. And lastly, they make the ultimate companions. Fish, snakes, cats, and rodents have nothing on a dog's loyalty.
