Flea-allergy dermatitis is a skin disease caused by a pet’s unusual sensitivity to flea bites. It is the most preventable of allergies by controlling the flea population in the pet’s environment. The most effective method of accomplishing this goal is with Frontline Topspot or Advantage (Over the counter flea topicals are often deadly to your pet). Symptomatic therapeutic measure include anti-inflammatory medications, antibiotics, and special shampoos, but the cure for pets is death to fleas. Although Frontline is labeled for monthly use, it often kills fleas for 8 or even 12 weeks. Although less expensive over-the-counter topicals like Hartz Mountain Control claim 3 weeks protection, barely three days are often accomplished and many pets suffer seizures, liver damage, coma and death.
