If you got him when you were nine and you're 24 now then that's around 15 years. That's a pretty good lifespan for a dog, so you can always take some comfort in the fact he lived a long life and was well-loved the entire time.
I sometimes think the reason we grieve for our pets so much is to harden us up for when people we love die...although for the really special ones it sometimes doesn't feel all that much different. Hang in there, because eventually the hurt fades and you can concentrate on just the happy memories.
what he said. thats a great life for a dog. you took good care of him and he knew it.. sorry to hear for your loss. i get more attached to dogs than i do most humans. they are great animals and great companions
