Step 1
Ask your veterinarian about treating your dog's scabies-infected skin with cephalexin. Although the Food and Drug Administration (FDA) has not approved the antibiotic for use in pets, it is a commonly prescribed "off-label" medication to treat infections of the skin in dogs and cats.

Step 2
Administer 10 to 15 mg of cephalexin per pound every 8 to 12 hours, as prescribed by your dog's veterinarian. The medication comes in liquid or pill form, so if your dog has trouble swallowing pills, ask for the liquid suspension, and mix it into his food.

Step 3
Make sure to continue giving your dog its medication until it is all gone. It is probable that your dog's symptoms will improve dramatically within a day or two, but keep administering the medicine.

Step 4
Keep your dog comfortable while she is healing by combing through her fur on a regular basis, checking for mites or other problems. Use a soothing shampoo with an antifungal agent to relieve itching and irritation. Try to keep your dog from biting, scratching or otherwise irritating her infected skin. You may have to use an Elizabethan (funnel) collar if her biting is persistent.
