I'm so sorry for your loss. Dogs give so much and ask almost nothing in return. They are the most innocent of the innocent, just living in the moment, having fun wherever and whenever they can get it.
We can learn a lot from them.
My wife cried and cried when she lost her chihuahua, that's her favorite. She only stopped crying when she adopted another.
That's pretty good advice. If you haven't done so, find another one. That's the only way to fill the hole in your soul.
