IIRC a lot of it depended on the size of the tribe. Smaller ones everyone was basically treated like an extended family group, so everything was very communal. Larger tribes had more in-group/out-group politics, where certain families within the tribe maintained their own family property. People being people, there is sometimes bonding that happens with some animals. A horse or a dog becomes “yours” because of mutual preference and affection, not economics.
