Complaint to Neighbours

Dear Mr. and Mrs. Brown,

I am writing to you to bring your attention to a problem I have been having with your dog at night.
As you may already be aware of, your dog has started making small detours at night around the neighborhood, digging holes in the gardens and often making loud noises. To make matters worse, I was awoken by your dog's barking several times lately, and I had even consulted a doctor and had been prescribed some sleeping pills. This wouldn’t have been as big of a problem for me if I wasn’t in the middle of my exams period, but since I am, it is crucial for me to get good rest and to sleep during the right proper hours;, as I have morning exams to wake up forto.
I am very upset with about this situation. Therefore, I would be grateful if you could have your dog looked after by another member of your family away from this neighborhood, even if only until my exams are over, which will be in about three weeks time. So, Please inform me of I want to know what you are going to do about this situation.
I look forward to receiving your reply and to resolving to this matter.

Yours sincerely,
Yana X
