Mello’s knee surgery

My name is Zac but many know me as Mello’s dad. He saved my life 9 years ago when my friend found Mello as a little pup. He has since been touching lives both in the front and back country. The adventures have taken a toll though and his knee pops out of place as he walks. He doesn’t whimper and still loves to play, but if he runs he will limp for the next following days. I have been to many vets and finally found a good one. I have been quoted between 3000-6000 for the surgery. I have been putting it off and honestly just scared I won’t have the same boy after. But I have come to a place where I want to know we have tried everything for him. I don’t accept help easily, and I know if I am to get this done I will need the help. Thank you for your support and time.
