I'm so sorry about Shiloh, Terrie.
We had a similar situation with our first setter--both with the biting and then with the mellowing into the best dog as he got older. The loss seems harder somehow when they've been a handful and then come around through your hard work and patience. We never get enough time with them. Bless you for sticking with Shiloh and giving him such a good life! I know how difficult, and eventually rewarding, that was.
And congratulations on your new little ones! Are they both shepherds, as well? I hope you'll share them with us!
Shiloh
