wolves will suit a dwarf very well, there could be a pet system that works with nature, Like NWN in nature companion, an elf might work well with a bear, a kran could work with a boar, ylian would work with an eagle and so on, yes the idea would work really well, but make it you start with a baby and you teach it tricks (not do a backflip, just fetch a stick and all the combat skills etc.) the growth will have 3 stages so it won\'t be really hard to make the models, it will just be baby, kid/teenager, fully grown. The idea will suit the roleplaying and it could help you in certain ways, the animal won\'t be able to be a mage, or an archer, though the animal could be a thief, it size would work and when it baby you could teach it thief skills, each animal will have its advantages and disadvantages though it will be a good idea
