Help protect your canine companion from pesky pests with the strength of Vectra 3D Flea & Tick Treatment for Small Dogs (11-20 pounds). This waterproof topical solution is formulated to provide your pup with up to one month of protection by killing and repelling fleas, mosquitoes, biting flies and sand flies, mites (excluding mange mites) and a variety of ticks including brown dog ticks, American dog ticks, deer ticks, gulf coast ticks and lone star ticks! But that’s not all—Vectra 3D can also help decrease flea feeding in just five minutes and help kill fleas that may cause flea allergy dermatitis, also known as hot spots, which can result in itching and discomfort. It’s also quick-drying, non-greasy and comes in a tube for easy application. Vectra 3D Flea & Tick Treatment is available in other sizes based on body weight (sold separately), so dogs from all barks of life can get the protection they need and deserve!

Key Benefits
  • Helps to kill and repel ticks, fleas, mosquitos, mites (excluding mange mites), lice, biting flies and sand flies.
  • Formulated to protect your BFF from pests for up to 1 month!
  • Helps prevent all flea stages from developing.
  • Waterproof solution dries quickly and isn’t greasy like other flea and tick treatments.
  • Available in other sizes (sold separately) so mutts and dogs from all breeds can get the protection they need.

Important Information

Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 30 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

    The best flea/tick preventative

    By on

    This is the best flea and tick preventative! I tried using a Seresto collar for my puppy when he was old enough for one but it actually caused him to have 2 seizures (vet checked him out, he was completely fine - I took it off and he hasn't had one since!) She recommended Vectra 3D moving forward and he hasn't had a bad reaction at all! I apply it at night so it can absorb as he sleeps and he's not greasy at all when he gets up in the morning! I haven't found a single flea or tick on him since using this stuff either, and we go hiking in the woods and into woodsy dog parks pretty often in the spring/summer! This is the best, highly recommended and SO glad Chewy carries it!!!

    Best flea and tick treatment

    By on

    I always use Vectra. So glad Chewy carries this product. Much cheaper then at the Vet's. You need to carry more from spring to fall. Was hard to get because you ran out so fast.

    No more ticks

    By on

    We live in the mountains, and was finding 2-3 ticks on my pups after every walk. Put this on all the dogs, and even when they're traipsing through tall grasses, they seem to be tick-free. We usually get Bravecto from the vet, but my vet recommended this as an external treatment and seems to work just as well. I don't think it lasts the full three months though.
