Q. Fleas? First noticed scabs & small lumps under chin & neck. Used hydrocotizone spray, flea collar, spray, baths...Is licking, has hair loss & swelling

Answered By

A. If you are currently treating for fleas with a flea prevention treatment, several things could be happening. It could be that your pet is experiencing a flea-bite allergy, even if the fleas themselves are gone, which is very common. This causes small, red, itchy bumps to appear on the body where fleas have previously bitten the area. If your pet is allowed to scratch or chew at these spots, it could lead to a bacterial infection under the skin which can become red, painful, hot to the touch or even cause the hair to be lost in the affected area. Making an appointment with your vet can determine if this is the case and treatment usually involves allergy medications and any antibiotics or anti-fungals needed to clear up a secondary infection.

Another cause of skin changes, swelling and hair loss are hormonal imbalances. Thyroid problems, adrenal gland problems and other hormone produces in the body can cause changes to appear on the coat and skin in affected animals. You may also notice other signs such as changes in appetite, thirst, urination or even in your pet's weight. A set of blood tests from your vet can determine if this is the case. Most of these conditions are treated successfully with the addition of a daily medication to balance the hormones.
