Welcome to the forum, and don't forget to post pictures. I have one sable female, named Emma, soon to be 10 months old. I had two previous Shelties, both males, Hamish and Noah.
Emma is also not a big chewer, except for the lattice work or the floor of the deck and this is usually when she has decided she wants inside. I agree - Kongs are great. My sister softens the dogs's food, puts it inside, and then freezes it (she does not have Shelties unfortunately, though she did in the past, and I got Hamish from her at 3 years of age).
You will never regret getting a Sheltie. They have so much love to give and can sense your every mood. Emma has become somewhat of a Velcro dog this past week and I am not sure what she will do when I go back to work.
Toys are great - there is such a variety out there. Emma really loves the smaller toys and really loves her hide-a-squirrel in the house and her Wham-a-Ham outside.
