Surgery for Service Dog's Eye

Kelsey is a 4-year old pomchi and is finishing her training to become my service dog.  She has developed cherry eye on her left eye that has failed to go back into place, despite frequent massaging and daily eye drops.  She needs surgery to put it back in place to prevent future issues with dry eyes.  Kelsey was adopted from a local shelter and was scared to death of everyone and anything, even toys.  She has come so far and is becoming much more social.  When I needed a service dog, she was the perfect candidate.  She is such a good and sweet girl.  She is with me 24/7, and I absolutely love it.  The problem is that I have been out on disability and struggling to make ends meet and paying for the surgery will be a challenge.
