Help Us Save Our Copper

We saved him once (from the shelter) and we can save him again, but we need YOUR HELP! Thank you for all your prayers and love sent our way, but sadly all the treament so far have not helped our Copper, he needs surgery. This surgery is slated to cost between $3,800-$4,500. This is a big ask, but if you have anything to spare, it can help us save him. 
Alanna, Brendan and Cian are besides themselves, and I just want to bring Copper home. He is only five, and with this surgery vets say he will be good as new!
