TPLO Surgery for Mikey

I'm raising money for my dog Mikey who is only 3 years old. He is a rescue. He was living in a cage his size shared with other dogs. When I got him he was only 16lbs and extremely malnourished. He has been loving his forever home and been flourishing. He is extremely energetic and loves hiking. However due to 2 torn ligaments in his back legs.

He can no longer run, take long walks, or even play like he used to.

Please help me in giving him a good life, any little bit helps. Thank you for your support
