Dear ....,
Thank you for your letter. Sorry for my late reply, I was busy with my studying.
I've read you letter and found out, that you don't do everything that you can.
If I were you, I would take him to the vet, due to he need different injections and regular check-ups. Moreover, you need to buy toys for him, as all dogs love to chew things. And finaly, don't forget to take your friend for a walk, because exercising is really important for him.
Hope my advice will help you a bit. I have to go now. Looking forward for you reply.
Best wishes,
...
