My mom worded it perfectly in her Facbeook status, so I’ll just copy that here.

One of the hardest things in life to do so is to love someone so much that it hurts to say goodbye, but you know you have to. That is where the love comes from. Today we had to say goodbye to our dog Sam. He was 12 years old and is the best dog anyone will ever have. He was kind and generous and loved without question. He lived tremendously, he was loved tremendously and he will be missed tremendously. So if you see me at work just give me a knowing smile, no words are needed. My heart is broken. I love you Sam. 

He was there for me more than anyone else I know. I love you, Sam. I’ll miss you.
