Help Coco run and play again

Im Coco, 6 years old, with bung knees, my mum really needs help to be able to pay the mountaining vet bills, and medications.

She has already tried to help me with $3000 operation to fix my luxating knee cap, this was a big operation, with 6 weeks recovery, with very limited movement and should have made a big difference to my quality of life. Unfortunately the outcome wasn't perfect and meant the vet wanted to re operation to try and fix and wanted to charge another $1800 to do this and another $3000 to do the other knee while they are there. This was just not possible for my Mum on single income. She has been trying to save madly but is definitely not wanting to use the same vet. She has saved $400 so far, I have been coping ok on the operated knee, I'm a pretty happy wee thing, don't complain, just rest a lot, but Mum says I'm putting on weight which isn't good for my knees. My other knee is finally getting to the point where it needs operated on soon as I can only walk for a little while before I start limping a bit, but I really love to be outside running and playing so this is bit hard. If there is any way you may be able to help, so my Mum can arrange my second operation on my knee's, so that I can run, jump and play, running around the park with sister Honey again. Soon.
