she tore her acl charface.. i took her with me in the car to go vote on election night, and when she jumped out of the car, she wouldn't walk in all four legs.. she had been kinda limping and favoring the one leg for a few days before that, but i think that's when she really hurt it..
so, she got that tplo surgery.. they cut the one bone in i think the tibia, that's the t part of tplo, then they move the bone a bit to better align the two bones along the axial line, and gave her a new, prosthetic ligament..
