help sassy hike again

My 2 year old Sasquatch needs knee surgery. She is suffering from a partially torn cruciate ligament. Last spring she post holed in the snow while hiking causing her injury. It’s getting worse to the point that she can’t walk without limping. Any donations help, If I come up with a chunk there’s payment plans I can do. For those who don’t know Sass she is a Great Pyrenees German Shepherd mix that lives to swim, hike, and chase any wild animal that moves! I need to get this squaw dog back into action her third birthday is next month.
