coloring, one-sided tail, and goofy walking

We've just adopted a St. Bernard/Great Pyr mix (according to the previous owner who had bought her from a pet store). At almost 12 months old, she's a dainty 68 pounds though fairly tall - in the one photo, floorboards are 6" wide for size reference. Build is narrow, back end is higher than front end. Her coloring seems unusual, almost more Anatolian with the mask, and overall color is shades of cream/biscuit, not white. Does Pyr coloring include dark muzzles? (but the spot on top of her head is hair dye - previous owner tried to cover purple hair dye that dripped on her when they were dying their own hair) When it does curl, her tail always curls to the right; is it normal to be partial to one side? A bigger concern is that she seems to bunny hop when running. She sits tight, though stands with her toes pointed out slightly; they usually point straight when she is walking. She seems to still be growing into her legs and movements are generally very bendy and wiggly. She's wiped out a few times dashing through sharp turns and clocked her nose into the wall turning around in the hallway.
Could bunny hopping still be normal puppy clutzness at this age? We'll be seeing the vet later this week or next week but they often don't know these breeds well. Our previous dogs were St. B mix and an Akbash mix they kept calling a white GSD (a very clumsy one until age 3 or 4).
