erm...well. uh. I love them both equally. but (don't hate me for saying this) I like spending time with Rusty a little more than I do with Tucker. Tuck is a wild man, and always on the go. but Rusty is so laid back and is just a gentleman....so if I'm ever kind of tired or sad or whatever, I usually go to Rusty and hang out with him for a while. and I baisically grew up with him...we're really close. while Tucker would rather spend time with my mom, Rusty would rather spend time with me. BUT of course I love playing with Tucker too. he has that puppy energy that Rusty doesn't have anymore. and he's just a sweety! I love them both equally.
