My heart is so heavy for you Gloria, that must have been traumatic. At least there was no doubt or second guessing that it was time, he rallied with your good care to extend his life. It is just mind-boggling the pain when we lose them... most of us here have gone down that path and we all know and feel for your loss. Many, many hugs to you.
Take care of yourself, you have earned a rest. Hug your dogs tight and may they comfort you as only they can.
