A few have the dog alone, most have the dog with one human "buddy," one guy even has his dog on a leash while riding his horse; a few have the whole family, usually with the dogs being held by a small person in front.

The dogs also vary widely - from Jack Russell terriers to Irish wolfhounds. A fair number are hunting dogs - one shows animal skins hanging on a wall, with the dog and hunter in front. Another just has a man with a long gun, his dog by his side. The are also cute fluffy ones, usually accompanied by a small child.
