Sending you huge hugs. You were a wonderful owner to him and especially in making that final hard decision. I have read Rainbow Bridge many times but it still brings tears to my eyes, thinking of my many animals I have lost. RIP Sunbeam.
So sorry for you zig zag, but at least sunbeam will not now be in pain and he will always remember what a kind thing you did for him at rainbow bridge.
With a name like Sunbeam I'm sure he'll soon fit in at rainbow bridge!
Well done for making an unselfish decision - you thought of your beautiful little man before your own feelings. He will always be grateful to you for that.
RIP Sunbeam - gallop free little man.
