Yesterday my boyfriend was playing with my almost 3 month old Mini Aussie puppy. While Azura was chewing on her bone he took it away from her (for play) and she aggressively bit him on the hand. We've taken toys and bones away from her before without problems. I don't know if this is a problem I should be concerned with or just something to expect from a puppy. I've never had a puppy do that before and I need some advice on how to handle her bitting if she does it again.
