(((HUGS)))
I am so sorry for the loss of sweet Bear. I lost my darling Dilly in a similar way. She went into a convulsion and died at the vets office. It was horrible. I totally know the shock and loss you feel. Take comfort in knowing that you did all you could for the sweet boy and he is no longer in pain. He has lots of animals to run and play with while he waits for you and angels laps to lay his head in when he wants to rest. You are all in my prayers.
