This past summer my dogs had fleas really bad even though they were on Frontline Plus every month. Even my cats got fleas and they don't go outside. While I was talking to the vet about the problem a flea crawled across Blue's face. I said, "See, Frontline's not working!" I think it's possible that fleas become immune to medications after awhile just like viruses in humans do.

My vet told me about a new product - Vectra 3D. It is made by Summit VetPharm and says it repels fleas, ticks and mosquitoes. It also kills 96% of the fleas in 6 hours. I didn't time it, but it worked very quickly without any noticeable skin irritation and the fleas stayed gone for a good month. It's great stuff.

Pros: It worked where others failed, also got a rebate check

Cons: expensive

I have found that the Vectra and ProMeris product lines are both effective in the fight against pests on our fur child. However, Summit VetPharm, the makers of Vectra, only allow their Vectra products to be sold through a veterinarian. Since most people only have one veterinarian, there is no free market competition and the price of Vectra is obnoxiously high (As much as $20 per monthly dose when buying a years supply.) There is a website that has a comparison chart showing qualities of ProMeris and Vectra. ProMeris not only costs a lot less than Vectra (11.50 - $12.50 per dose), it can last up to 3 weeks longer than Vectra and ProMeris can also be used to effectively treat demodectic mange on dogs. That website is nomorefleasplease.com and on their home page, there is a tab for the ProMeris vs Vectra. Every product will have people who either love it or hate it so you really can't go by a review. What did not work for someone else may work incredibly for you. These products would not be on the market if they didn't work. Anyway, I hope you find this info useful.

Pros: Both work great

Cons: You can only Pay Vet prices for Vectra as it is not available online

I got my puppy in the winter and didnt think anything of it, that he may get ticks while playing outside. Well he came in one day with 3 on him and then the next day with more on him. So I asked my vet which one she recommened (frontline or advantix) and she said neither. She recommoned Vectra. I put it on him and he hasnt had one tick or flea on him since.

The VET said that both of the other lines are good but ticks and fleas are becoming used to them. I believe Vectra 3D is on the newer side, alittle more expensive but works great.

Pros: Easy to use

Cons: Expensive

Vectra 3D is a new product by Summit VerPharm that promises to kill not only fleas and ticks but also repel mosquitos. While it is a new product and not yet widely used or available, it has proven to be effective and comes with a manufacturers guarantee by only distributing the product to veterinarians.

Pros: applicator tip, works on mosquitos

Cons: higher amount to dispense, not widely available

This new product has worked great so far on my 100lb German Shepherd. After a number of walks through densely wooded trail areas, no sign of any pests. This product is also unique in its ability to repel target insects. Talk to your vet about it!

Pros: Easy applicator

Cons: Greater volume to apply
