Dear [name],
Thanks for your letter. It was lovely to hear from you.
Speaking of pets, I've always wanted to have a dog, too. Eventually, my parents decided to agree and bought me a large dog although we also live in a flat. I think you should convince them to buy a dog anyway because not only you will have a pet but also a true friend! My mom used to be angry about the mess my dog caused but she got used to it.
By the way, is your flat really small? If so, you might consider buying a smaller dog anyway. Is there enough space for your pet? The good thing is that in case your flat is small,you won't have to do a lot of cleaning. Do you usually do the housework?
Well, I have to go now. I promised my Mom to clean the bathroom.
Can't wait to hear from you!
Love,
