Medical care for Magnus

Meet Magnus. He is a sweet boy just over a year old. I rescued him from a terrible life. He lived in a 3x5 pen with two other dogs in the heat laying in their own pee and poop with very little food and water. Only being let out so the owner could hose the pen out At night and then back in they would go. Magnus has a systemic skin infection, both ears and eyes are infected, and grossly under weight. He has not had any vet care since he was a puppy. I am asking for your generosity to help fund some of Magnus's vet bills to get him back on the road to health and happiness. Any help will be greatly appreciated in saving this sweet soul.
