Marleys operation

Hello all! First of all, thank you for taking the time to read this, I'm very grateful. So, my dog Marley (also my BFF) is in need of an operation. He has a shoulder mis-placement at only 9 months old and this operation is going to cost over £2500, which is way over what me and my mum can afford, we wish we could. Marley is a big part of our lives and at only 9 months old we hate that he is this poorly. We are already his third home and will not re home him and we love him so much and sending him to a fourth family with such a big bill is not fair on him or the family., and the only other option is so put him completely out of pain and send him to sleep,, which will be our very LAST resort. We just want Marley to get better and be the healthy, hyper and loving dog he always is. We would really appreciate if you could help get him on the road to recovery!
