Your Samba is absolutely adorable, Kate! A Sheltie would be my second choice if we got a dog, the Malemute being my first. Living here in snow country it is a lot harder to be taking the pooch for walks. I can't do it, and hubby works a lot of hours---so it would be up to me to figure out what to do!
Not only the walking when it's icy and such, but its way too cold to keep pets outside and not be totally cruel. We can keep our cats indoors all the time and don't have to worry about something happening to them.
I just know you're going to be very happy that you got him!
hugs,
Annie
