The application is straightforward. The packaging is clear about how to use it. If you've got a dog that needs flea and tick protection, this is solid. Better than dealing with the alternative of a flea-infested dog scratching constantly. Worth every penny for peace of mind that your pet is protected. Review: A treatment that works - I have 3 dogs and they were diving me crazy scratching. I was told it was food allergies, dry skin, nerves, and so on. I did spot a flea on my mini doodle that would cry in frustration as she scratched herself. I looked for a flea treatment that was rated good as most claim they don’t work well or for very long. I came across Vectra 3D and read the feedback. It had the best ratings so I thought I would try it out. What a surprise! I treated my dogs who were scratching all the time and in a few hours had settled down and were a lot calmer. The next day was the 1st day they quit scratching all day. The little mini doodle was sleeping with no problems. My standard poodle quit scratching and my Malanois seems fine. Even though I couldn’t see the fleas, they were on them. Vectra 3D really helped them. I would recommend this treatment for sure. They still scratch a little once in a while probably because of the bites they had before the treatment. I’m very happy and will continue to treat them with Vectra 3D monthly. I would recommend this treatment for your dog also. ## Features - FLEA, TICK & MOSQUITO PROTECTION FOR DOGS: Vectra 3D provides powerful flea and tick prevention for dogs while also repelling mosquitoes.

But last year had to take Georgia to vet for scratching. She had fleas so this did not work. Bad that I had ordered early to have and seller would not take the new package back. We ended with $150 bill and our vet put Georgia on Bravecto pills. Just make sure if order 6 doses before you need since company will not take them back even though I had receipt of vet bill. **Q: My girl back andd forth between 53-58#, which one should I get?** A: If it was my dog I would get the 56# and up size if my dog’s weight tended more often toward 58#. The difference is in the amount of product to put on the dog. The bigger the dog, the more product needed. I would also consider whether my dog is flea allergic, and if the area has a lot of fleas or ticks. **Q: What is expiration date?** A: This product is a US EPA registered product, it does not have an expiration date ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works exactly like it should *by W***M on June 16, 2026* Been using this for my dog for months now.
