Rosco's Medical Costs

Please help Rosco! He has been sick for weeks and today he had fluid from his chest removed via chest tube. The vet found masses on his spleen and tomorrow he will have surgery to remove his spleen. We are hopeful that it isn't cancer, but until the masses are removed we don't know for sure. Rosco is the baby of my dear friends, Courtney and Drew. Any help is very appreciated!! The surgeries and medical care are very expensive, I'm not trying to raise it all, just a portion of it. Help me, help them, save their baby, Rosco!!
