Without seeing your dog, it is hard to say but it sounds like sarcoptic mange. Here is some information on the subject from petsmd however;you should consult with your veterinarian as soon as you are able.
Source & cause(s)
Sarcoptic mange is caused by a tiny microscopic mite that feeds on material in and on the skin surface. this mite burrows into the skin where it lays its and when they hatch, your pet will have an outbreak of mange. sarcoptic mange is highly contagious, and can be transmitted from one infected dog to another, and is seen mostly in shelters or puppy mills where there are large numbers of dogs living together. the mite that infects dogs, sarcoptes scabiei is structurally the same as the mite that infects humans.
Signs & symptoms
redness of skin
hair loss most commonly on legs, belly and ears.
areas of thickened, flaky skin
the presence of the sarcoptic mite causes extreme itching; your dog will chew and scratch its skin constantly. eventually, the skin will become thickened and can cause a secondary bacterial skin infection.
