I agree that it's a very personal decision, to euthanize in the first place and to stay with the pet during. I know I've had a very hard time not fixating on that one final memory of Sophie. It's very tough for sure. My heart goes out to anyone who has to make that decision.
But, oh, how they're worth all that pain.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
