He is DARN cute, and wonderfully snuggly. (You're one of few people who would understand that when I call him my little Mer-rat, I am complementing my favorites of his personality traits.) Unfortunately, he also has a prey drive that won't quit, a nonsensical desire to "protect" his little sister from the dogs she wants to roughhouse with, and other unpleasant habits left over from either his life on the streets or his shameful Sheltie genetics!

foobart pointed out that Sheltie people may be more useful than BC people in figuring out how to deal with him.

Or at least, that would be true if we'd ever met any Sheltie people who could admit that their dogs have some less-than-perfect personality traits!
