Thank you for releasing Max from his earthly body; it sounded like it was the right time do the ultimate act of love for your doggie. His spirit is free of a malfunctioning body and he is onto the next phase of existence. I know it hurts not having him near; but remember only his physical body is gone, not his spirit; he is still with you, in your heart, for as long as you live. Try and smile through your tears; remember the love, the happy times and the courage you showed in letting go of his physical existence so he could have peace. Celebrate sharing your life with him and remember.
