In general, dogs make better companions for people than for horses. The reason that so many of them can work well around horses is that their pack mentality makes it important to them to please their people, and if their people clearly want them to play nicely with horses, they're quite willing to do so.
Of course, like all generalities there are exceptions to this rule -- dogs who seem to automatically bond with horses and horses who claim dogs as buddies of their own. Some dogs also naturally seem to like tagging along with working horses. Trotting along beside of or in front of a horse and rider offers the same thrill as a walk -- new sights, new smells, and the simple release of energy through action. Many dogs are also highly task-motivated, so when called upon to accompany a rider or group of riders hunting or herding or pursuing some other purposeful activity, these dogs are very happy to lend a helping paw.

All that changed with what I'm calling "Project Puppers" -- the introduction of the Companion Animal series to the Breyer line-up in 1999. While the Companion Animal line also included some cats, a goat, and a miniature donkey, the emphasis was clearly on providing in-scale canine chums for Breyer horses. Unlike Breyer's first in-scale cattle, which were conceived to go with Breyer Classic scale horses, Companion Animal dogs were designed to pair with Traditional size models.
With later additions to the Companion Animals line, the link to horse-keeping was not always as obvious. The Australian Shepherd, the Border Collie, and to some extent the Shetland Sheepdog were all obvious herding helpers, the Dalmatian a well-known carriage companion, and the Foxhound and Beagle both hunting companions. But when it came to such animals as the Great Dane, the Irish Setter, and the Rottweiler you had to put your imagination to work to figure out how to pair them with performance horses.
