I'm so sorry for your loss. I know that "look" you described, when it is time.
They mean so much to us and yet we have so little time to learn from them.
I like to think of them all together enjoying the next life, in a world where there are plenty of pets and treats.
Cara was a beautiful dog. It's so sad to lose a beloved family member. Be consoled in knowing you gave her a great home.
As a fellow dog lover, I can understand what you're feeling.
I saw this quote on a plaque in our vets office: Dogs are how people would be if the important stuff is all that mattered to us.
