Is it normal for my dog to be aggressive when I'm not home?

It's possible that your dog is feeling anxious or stressed, and may display aggression as a result. You should try to spend more time with them during the day, give them plenty of exercise and playtime, and make sure they have enough attention and affection from you. If these steps don't help, then you should consult a veterinarian to discuss other options such as medication or behavior therapy.
