Morky surgery

My Dad has been having serious medical problems (leukemia) and he has a Yorkshire Terrier named Morky who has been helping him emotionally through the treatments. Unfortunately Morky has a subluxating patella (her knee bone does not stay in the groove), which has caused a torn ACL.  She needs surgery to correct this and it will cost $1100 for one knee. The doctor says it will eventually happen with her other knee. Any amount that you can give, even if it seems small, will help. 

The original $3500 was because we thought her insurance wasn't going to pay any of the costs because the subluxating patella is a pre-existing condition.
