Dear [Friend's Name],
I hope you are well!
Guess what? My dog just had puppies, and they are absolutely adorable! They are black and brown, and so incredibly cute, funny, and friendly. They love to sleep and play all day long.
I know you've been looking for a pet, and I immediately thought of you. I'm writing to offer you one of the puppies. I think one of them would be a perfect addition to your family.
They are being fed special puppy food and drinking water. I'm checking with my mum and dad about what needs to be done before they can go to a new home.
Let me know if you're interested, and we can arrange for you to meet them!
Best,
[Your Name]
