Our dermatologists tell us to provide one of the newer prescription products available from your dog's vet even if fleas aren’t seen. Over the counter products containing imidocloprid (Advantage, e.g.) or fipronil (Frontline, e.g.) may be ineffective because many populations of fleas have developed resistance to those chemicals. Consider products containing a different class of insecticide such as Bravecto, NexGard, Comfortis, and Vectra. New prescription products are becoming available all of the time. Dogs can be such effective groomers so as to eliminate all evidence of flea infestation. Dogs who remain primarily indoors can contract fleas because we walk them in on us and flea eggs and larva can remain viable in your home for months. As the weather warms or you turn on heaters at this time of year, egg hatches are common. If the area between the edge of your dog's rib cage and tail (the “saddle” area) is particularly excoriated, a flea saliva allergy should be the most important differential diagnosis. In severe cases, an anti-allergenic prescription glucocorticosteroid such as prednisone will work wonders for dogs allergic to the saliva of the flea. If you have other pets they may have fleas too but may not be allergic to the flea’s saliva. Be sure to treat your premises as well. Sprays rather than the inefficient foggers should contain an insect growth regulator (IGR) such as methoprene. You can find such a spray over the counter in pet/feed stores such as Siphotrol Area Treatment Spray. IGRs don't allow flea eggs or larvae to develop into adult fleas thus breaking up the life cycle of the flea. A professional fumigator might be enlisted if you prefer.

Hi Nunu,

I'm just following up on our conversation about Emmanuel Dotson. How is everything going?
