I am SO glad that Sasha has survived her trauma and is recuperating.  Kudos to the trap owner for rendering aid and good judgement by coming forward to ensure Sasha's return to her owner and quick pathing her road to recovery.  I believe there is a foundation that does animal prosthetics.  I want to say searching PBS may help but I know as a Smithsonian subscriber, they have articles such as this topic. Last year one issue highlighted the dog species on it's cover. Yeah Sasha for being a tough Alaskan girl!!
