FHO Surgery for Kevin the BC

Kevin(named Frankie at the shelter) was picked up in Woodland, CA on April 27th with a makeshift rope harness tied around his body. He was afraid to be touched and could only be taken out of the kennel run by one staff member after two weeks.
I met him on May 23rd with my old dog and they had a friendly meeting. I brought Kevin home and he found a ball to play with and brought it to me. He's been a playful boy since, discovering all kinds of fun toys.
He was scared of being touched the first few days and sometimes he is still scared. Now I can pet and snuggle with him and he sometimes gives me kisses. He even jumped in the shower with me one day and let me give him a bath.
Kevin was weak in his hind end and limping a little, so I brought him to South Davis Veterinary Clinic where he was diagnosed with a luxated hip.

It is a very painful condition which explains why he is afraid of being touched. He needs to have a femoral head ostectomy in order to keep the head of the femur from rubbing painfully on his hip and to allow it to built a new joint capsule for cushion. His hip has probably been like this since he was picked up in Woodland and explains his fear and aggression. Once he has the surgery and isn't painful anymore, he will make for a wonderful adoptable companion.
Will you help me help him? He and I would be extremely grateful.
