Grief is love.

I mean, imagine if your dog died and you felt nothing. The memories will bring her spirit into the future with you.

I did like that one anonymous quote:

It came to me that every time I lose a dog they take a piece of my heart with them, and every new dog who comes into my life gifts me with a piece of their heart. If I live long enough, all the components of my heart will be dog, and I will become as generous and loving as they are.
