Sorry to hear you're having such a hard time! I'm no expert, but I'm pretty strict (I'm a teacher... I guess it goes with the territory!) so I'd keep telling the dog NO when she snaps. I'd also make sure to give her lots of attention for good behavior, and not just for bad, or all she'll do is be naughty to get your attention.
Maybe try to play ball with both of them? Or, try another game that the snappy dog likes and introduce Tink to it. LOTS of praise for both dogs is important when they're doing what you want (behaving!), but I'm sure you already know that!
Good luck!
