I thought it would be interesting to see what types of dogs people have, rather than always classifying them by breeds.

Herding Dogs
such as cattle dogs, sheepdogs, german shepherds.

Hunting Dogs
such as pointers, retrievers, setters, and spaniels.

Sight hounds
such as greyhounds, Afghans, saluki.

spitz- type dogs
Spitz, Akita, papillon.

Scenthounds
such as beagle, basset, ridgeback, doberman.

Terriers
yorkie, pit bull, miniature schnauzer, dachshund.

Companion
Bulldog, shih tzu, chihuahua, poodle

These were the only groups I could think of, I put an "other" in case I forgot a group, or you dog doesn't fit into one of these groups.
