Dogs suffering from flea allergy dermatitis may exhibit large areas of inflammation, red bumps or hair loss. The condition occurs when a dog experiences an allergic reaction to the chemicals in a flea’s saliva. When the dog scratches, bites or licks the bites, it causes a breakdown in the skin, which allows bacteria to colonize the wound. The best way to prevent this condition is by eliminating fleas from your pet and his environment.
A variety of over-the-counter and prescription medications are available to treat flea infestations. Long-acting, topical liquids are often the most convenient medications, but flea sprays, dips and oral medications are also effective. Always be sure to treat your pet on the correct schedule, to prevent lapses in flea protection. It is important to treat the dog’s environment, especially his bedding, because that is where fleas often deposit their eggs. Consult your veterinarian for the right treatment for your dog.
