My favorite flea products for dogs

Protecting your dog from fleas is much easier than it was 20 years ago. Back then, the best we could do was knock the flea numbers down, but it was challenging with the products that were available.  Lately, the problem is knowing which of the many products out there is right for your dog. I’ll give you my 3 favorites, starting this week with number 3:

Vectra 3D is at the top of my list for topical products (spoiler alert: the top two are given orally). It combats fleas (plus ticks and mosquitoes) on three fronts:

1.  One ingredient (dinotefuran) over-stimulates the fleas’ nervous system. It acts on an insect nervous system receptor, leaving a wide margin of safety for mammals.

2. The second ingredient is permethrin, which helps repel mosquitoes, kill ticks, and fleas.

3. The third ingredient is an “insect growth regulator” called pyriproxyfen.  This ensures that even if eggs are laid by a few surviving fleas, they will not result in an infestation.

Vectra 3D is quite safe for most dogs if applied according to the label, but always consult with your veterinarian for recommendations concerning your individual dog.
