Thank you for submitting your question regarding Oscar. The growling does indicate aggression. In the situation you described it typically results from fear. This can be impacted by genetics, but is most commonly the result of poor or inadequate socialization as a puppy. A puppy's socialization window is roughly from 8-14 weeks of age. During this time frame, the puppy needs to have many new and positive experiences to prepare him to be well adjusted in adulthood. It is worth seeking out some training classes for him. You will also want to consult with his veterinarian to rule out any medication issue affecting his behavior. I hope this information helps!
