Why is my dog so itchy and scratching his back until it's raw?
Poor Frank! This itching can be caused by fleas, mites, ringworm, or allergies. If he isn't up to date on his flea treatment, I would give him Capstar. It's a one time pill that starts killing fleas within 30 minutes. Then follow up with a spot on treatment, such as Advantage or Revolution. This is a treatment that has to be used once a month. You will also have to disinfect the environment. Wash his bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home.
If he is up to date on his flea treatment, I recommend taking him into the vet for an exam Monday. The vet can do blood tests, skin scrapings, and use a Wood's lamp to diagnose allergies, mites, and ringworm. Once the cause of the itching is found, the vet can prescribe the appropriate treatment. Good luck, I hope this helps!
