Tucker squats, too. He's 8 weeks and I plan on getting him fixed as soon as possible because I don't want him to "go male"!
My parents bred and raised border collies and our oldest, Spencer, raises his leg but he's still an intact male. One of our "puppies" (he's part of the youngest bunch but he's 4 years old!), Freckles, was fixed before he was 1 and he has never raised his leg.
