How fast does Vectra 3D work?

It starts reducing flea feeding within about five minutes and kills fleas within four hours. Full protection against ticks builds over the first day or two.

Yes, after the dose dries and bonds, about 24 hours after application. Bathing or swimming before then can wash it off.

Can I use it on puppies?

It is labeled for dogs and puppies from 8 weeks of age, in weight-specific sizes. Check the weight range on the box before applying.

How does it compare with oral flea pills?

It covers more pests, including mosquitoes and flies, and needs no prescription. Pills avoid the wet spot and skin irritation but usually do not repel mosquitoes.

Three single-dose applicators, one per month for three months. Each dose is applied directly to the skin between the shoulder blades.

What should I do if my dog reacts?

Bathe the dog with mild soap if the reaction is at the application site, and call your vet if there is vomiting, weakness or wobbliness.
