This dog seems friendly, despite the appearance of several dangerous spines arranged on its body.

Spines (Ex) A foe striking a bearasaurus with natural weapons, an unarmed strike, or a one-handed weapon takes 1d3 points of piercing damage. A creature grappling a bearasaurus takes 2d4 points of piercing damage each round it does so.
A cross between a hunting dog and a stegosaurus created the first bearasaurus, and, despite the oddly personal nature of this creation, the formula has disseminated to others who have created bearasauruses of their own. Bearasauruses all possess a keen intellect and a strong desire to perform good deeds, much to the chagrin of those expecting yet another murder machine. This is not to say that bearasauruses will not harm another creature; they will definitely do so if it supports the greater good, or protects those with whom they ally.
