Hi Camy-

That is so sad to hear. We lost our sheltie last summer, and we still think
of him daily and talk of him often. So I can identify with part of your
loss.
The part where he was almost literally part of you, I can  only imagine.

Twain loved pets. In fact, on his travels he would sometimes rent cats  to
keep him company.

My wife and I grieve with you.

Love and Best Regards,

Tom Swenson
