Ok so this puppy showed up at my house and I don't have the heart to turn it away. My hubby says hes gonna die and tried to shoo him off the property but I decided to keep him. He is limping on his hind leg and is very skinny. I think he might have been hit by a car, I'm not sure he has no cuts or anything just the limping. I can't afford to take him to the vet and I know if I call the dog catcher they're just going to kill him. What can I do to help him with his leg is there anything I could get to get him healthy again? If you've helped a dog like this b4 what did u do?
