When I was just a little kid my parents let my brother and I get a dog, and he was the best but unfortunately he passed away.
Oh, that is so sad. What kind of dog was he. How long did he live for?
He lived over 10 years, and he was just a mixed breed. I was definitely very sad when he passed but we have a lot of great memories together.
Sounds like you had lots of great times together. You will have to remember those while you grieve.
