How to comfort the anxious dog?

    My landlord's wife has returning work from home to her office after the alert reduces to level 2. There is nobody at home during working days. No air-conditioned and nobody played with my playful dog. Her behaviour has rapidly changed to more aggressive especially heat summer in these few days. Recently our neighbours were decorating his new house and making some loud noise on the noon during my office time. My lovely dog has become more anxious and uncomfortable, therefore it chewing or hurt her front legs and cause bleeding.

    I have left my office during rest time at noon in these 2 days to take care of her unhealthy behaviours. There are some improving ways that could be for reference:

1. Exercise: I usually walk her 3 times a day but she did not like to walk too long distances, therefore this item should be ignored

2. Physical contact: Hug her, talk to her and release some cosy music for her, and combing her fur or hair

3. Massage: massage her from the neck to her butt

4. Music therapy: I love to put Miyazaki Hayao music to comfort her anxiety

Above these items could be useful for my dog, but it still needs more time and energy for treatment
