    How To Apply:
    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.
    5. Using the tip of the applicator, part the hair down to the level of the skin and slowly apply the product. Avoid superficial application to the animal's hair.

      For dogs weighing 2.5 to 20 lbs, apply the product to one spot onto the skin, squeezing the applicator tube until empty.

      For dogs weighing 21 To 55 lbs or for dogs weighing 56 To 95 lbs, apply the product evenly to three spots along the dog's back, beginning between the shoulder blades and continuing in the order shown in the diagram, squeezing the applicator tube until empty.

      For dogs weighing over 95 lbs, apply the product evenly to four spots on the dog's back, beginning between the shoulder blades and continuing in the order shown in the diagram, squeezing the applicator tube until empty.
    6. Discard empty applicator tube as outlined in the storage and disposal.
    7. Repeat every month, or as recommended by your veterinarian. Do not apply in less than 30 days.
    8. For treatment, control and prevention of fleas, flea eggs, flea larvae, flea pupae, ticks, mosquitoes, lice, sand flies and mites, year-round treatment is recommended.

    Did not work!

    Fleas must be immune to all flea products this year! All that I've tried anyway. Still has lots of fleas! We sprayed the yard, cleaned the dog beds, and sprayed the house. Wish I could say otherwise.

    I have come to trust in the safety and effectiveness of this product over several years of buying it. Entirely Pets offers it at a good price, with quick delivery time.

    Almost as soon as I applied the Vectra my puppy started scratching and biting herself. Over a week later, the reactions finally are starting to subside.

    Great topical prevention for fleas and ticks!
    January 7, 2021
    Have used Vectra for my dogs for years and have had no problems with fleas or ticks. I like that
    Vectra has a repellency factor which causes insect paralysis...insects don't always have to bite to die. I appreciate the good selection of products at Entirely Pets and the great prices.
    • Very good protection for pet, trusted manufacturer and supplier.
    • A little oily upon application in the hair around skin but does go away after a short time.

    Absolutely the best product for a great price! Works great on both of our dogs! Haven't had any fleas, ticks or anything since applying. Will definitely be buying again!

    Really Works!
    May 26, 2018
    Our vet recommended this when Frontline stopped working and other products made our Westie lethargic after application. We've been using it for almost 3 years and it's been great! I don't like the price tag, but it's really worth it.
    • Easy to apply/doesn't bother my dog
    • Doesn't dry too quickly, price

    I've been using this product for several years. It works great on my dog. Nice to have it delivered to my door Instead of driving to the vets office. I highly recommend this product. It keeps fleas & ticks from jumping on my dog in the first place!

    Great product. Works when other products quit working. Product is used on dogs that are in the water frequently in warm weather.

    This tick repellent really works and if I find a tick on Coco it is dead. Very easy to apply and can use seasonally when ticks and mosquitoes are active.

    Very effective product

    We have been using this treatment for more than 3 years and have never had a flea or tick problem with our two border collie/lab dogs. We live in a suburban location and they are free to roam our 1/2 acre lot but they do not go to wooded areas or dog parks. Just wanted you to know their environment for this review.

    I like the fact that it doesn't burn their skin or make them sick unlike some others have.

    It really works
    April 25, 2016
    We used many prescription Tick repellents but none worked reliably. After starting to use Vectra 3D more than 3 years ago, either we find no ticks on our dogs or they are dead when we pull one off. It's wonderful not to have to worry about our dogs getting disease from ticks! And it's so easy to apply one person can do it easily.

    We've been using Vectra 3D on our two border collie mix boys for more than 3 years with not one flea or tick. And the 15% discount made the price at EP more attractive than buying from the vet.

    I prefer Vectra 3D to any other flea & tick prevention and it's very hard to find anymore it was a great relief to be able to purchase it from you and at a reasonable price.

    Review for Vectra 3D PURPLE for Dogs 56-95 lbs - 3 Doses
    March 19, 2015
    Product is good, but I will never order from Entirely Pets again. I paid for the 2-4 days shipping and they did not send it that way. It took 10 days to get it. When I call customer service they said they would reship the product and refound the money for postage and they didn't. They don't do what they say.

    Am new to this product, used to apply Frontline Plus but this is far better. No side effects on my Akita puppy (6 months) and it seems to repel ticks as well.

    This is a great product. It works VERY well. (Remember do not use dog flea treatment on cats it can kill them. Keep your kitty away from dogs with freshly applied treatment for 12-24 hours.)

    Best Flea Treatment
    August 15, 2014
    I use Vectra Products on my two dogs and the Vectra Cat Treatment for my kitty. (WARNING: dog flea treatment can kill cats.) I've never had any bad side effects with this product and it works well. I've had problems with other treatments which were not strong enough.

    Doesn't seem to be strong enough
    August 6, 2014
    I have observed that after my dog returns from day care she continues to scratch and chew - signs that there are flees at the day care, so what is new. I just expect the product to protect her and maybe it does in the long road but initially she has difficulty.

    This is the best tick and flea repellant I have used, however, it is difficult to buy other than the vet's office. Thank you Entirely Pets for carrying this product.
