You have to call the game warden................mange is dangerous to all the dogs in the area. Please do not feed it...............then it will want to stay and it could cause dangerous problems as mange is highly contageous. Any siliva can transfer it and what it it bites someone who is trying to help it. It's illegal in Pa to feed wildlife. My B-I-L did not know that he has a red fox den by his creek, he always walked his dogs on a lease down there...........they both got the mange and they had to go thru a lot of meds to survive.
