The only model for now is the wolfie, but I managed to make several breeds with differences in size, color, ability, and when you buy them, cost.
The gentlemen in the back are all members of the Argent Legion, a Spearman, Patroller, Scout (with a cool scout hat! Standard soft headress for all members of the Argent Legion) and an archer.
The dogs are as follows in order, each with a detailed description included when you buy them:
Ahrnhand (pronounced ARN-and, both H's are silent), or the Royal Dog, is a western canine that has its origins in what is today the Purple Marches of Tethyr.
The Daeraman (pronounced DEER-eh-men by everyone but the dwarves, who pronounce it da-ere-A-man) is also known as the Dwarven Dog.
Darovoi (pronounced dar-eh-VOI) is both the singular and plural of this vicious breed.
Femmari (FEM-air-ee) were likely a cross between corgi and beagles
The Garygan (gare-E-gann) is a rare dog which were reportedly first seen in Halruaa, but over the past two centuries have become recognizable in the North as well.
The Itago (eye-TA-go) are a miniature breed of dogs which are used throughout the East by merchants and caravan masters.
The Mot (MAHT) may have originated in Chult.
And don't mess with the Darovoi! They are all between 2 and 10 hps, level 1 fighter or commoner, some with feats and skills such as spot, listen, search, dodge, tumble, and knockdown (for the Darovoi!). Some are wimpy but awesome trackers (like the Mot). Others have absolutelty no use but to be cute and cuddly (like the Femmari) and others are extremely rare and have a blue glow but you ain't nobody at the Oscars without one (ie the Garygan). The main attack dog is the Darovoi, expensive but trained and well worth the gold for low level adventurers who like a little edge. But, if you ain't got the gold and want a loyal tough companion that spots trouble, I'd go for the Daeraman, best animal for your money if you want to live through level 1
