How does Vectra 3D for Dogs work?

Vectra 3D contains active ingredients of Permethrin, Pyriproxyfen, and Dinotefuran, which kill and repel mites (except for mange mites), sand flies, biting flies, lice, mosquitoes, ticks, and fleas. It uses a "hot foot" reaction to repel parasites as they come into contact with your dog's skin or coat and subsequently with Vectra 3D. The pests will then retreat back up the shaft of the hair without biting, ultimately dying. Mosquitoes detect the active ingredients in this product and avoid dogs, choosing not to even land on them 80% of the time.



Active ingredient(s):

Dinotefuran 4.95%, Pyriproxyfen 0.44%, and Permethrin 36.08%

What are the side effects of Vectra 3D for Dogs?

The most common side effect of this and any pesticide is pruritus, erythema, or slight transitory redness at the application site. If a sign of sensitivity occurs, use mild shampoo or soap to bathe your dog, then rinse with plenty of water. If sensitivity signs occur and fail to resolve, notify your veterinarian. Be sure to keep the product label or container handy when speaking with your veterinarian.

What special precautions are there?

  • Keep out of reach of animals and children.
  • Only safe for external use on dogs.
  • NOT for use on cats. Because of their unique physiology and their inability to metabolize the compounds in this product, it cannot be used on cats. If applied to a cat or ingested by a cat that grooms a recently-treated dog, serious harmful effects can occur. If this occurs, seek immediate veterinary attention.
  • Do not allow contact with clothing, skin, or eyes.
  • Causes harm if absorbed through the skin or swallowed.
  • Causes temporary but substantial injury to the eyes.
  • If clothing contact occurs, remove the clothing and wash it before re-wearing.
  • Thoroughly wash hands with soap and water after use and before using the bathroom, using tobacco, drinking, or eating.
  • Do not use on pesticide-sensitive, nursing, pregnant, medicated, aged, or debilitated dogs without veterinary approval.

What to do if overdose?

Contact your closest emergency pet hospital.

How can I store Vectra 3D for Dogs?

Don't freeze. Store in a dry and cool place. Don't reuse empty container. If container is still partially filled, call your local solid waste agency for disposal instructions. Never place unused products down any indoor or outdoor drain.

Helpful Tips:

Vectra 3D is an excellent, broad-spectrum option for parasite control, because simply treating adult flea infestations will leave your dog exposed to 95% of the problem.




2. Remove applicator from package.

3. The dog should be standing or in a comfortable position for easy application.

4. Holding the applicator tube upright, place thumb and index finger around the applicator tip under the large disk. With other hand, grasp the stem of applicator tip above smaller disk. Press down firmly on small disk until both disks meet, piercing the seal. See illustration.

6. Discard empty applicator tube as outlined in Storage and Disposal.

7. Repeat every month or as recommended by your veterinarian. Do not apply in less than 30 days.

8. For optimum treatment, control and prevention of adult and immature fleas, ticks, mosquitoes, lice, biting and sand flies and mites (excluding mange mites) year-round treatment is recommended.
