I'm afraid it's hard to say why Prince might be acting aggressive without more information - aggression in dogs can have many different causes. Some common possible causes for aggressive behavior would include fear/anxiety, stress, resource guarding, frustration or over-arousal, or playful biting and mouthing which some owners interpret as aggression. Feel free to post another question with more details, or request a one-on-one consultation with one of us for a more in-depth discussion about your concerns if you prefer - we would be happy to try and help.
