Instruction:
Write a friendly, convincing e-mail to my landlord asking whether I can get a dog.

Response:
Dear landlord, 

I hope you've had a great start to your day and all is well! I've really enjoyed living in your building and amenities. In my time residing here, I've been a clean and respectful tenant. I'm very interested in getting a dog and would like to stay in your building however, I wanted to check with you first if the building is dog friendly. If so, are there any restrictions such as size or breed? Additionally are there any additional costs or changes to my lease I can expect? 

I look forward to hearing from you and I hope we can make this work! 

Best,
Tenant
