Read consumer reviews to see why people rate Vectra 3D 1.6 out of 5
The first time I bought Vectra 3D was from my vet for my 3 dogs. It worked fine and there was no problem with irritation like the other reviewers had. Maybe it reacts different on certain breeds. Since then, I found it cheaper online and have continued to use it. It costs a little more than Frontline Plus, but that what our vet recommended and it does the job.

I have not yet tried Vectra 3D — the reason is that I do thorough research/get background information on ANY MEDICATION before giving to my dogs. All of the information I’ve read/reviewed online, and that is openly available on the web, is implicitly clear NOT TO GIVE SMALL DOGS OR CATS Vectra 3D. I cannot understand those of you who administered this to the small breeds listed on this list serve. I encourage all of you to read up on this product and all products. BTW…remember, your Vet is a generalist, not a specialist — they cannot and do not know everything on a product or treatment. ALWAYS DO YOUR OWN HOMEWORK…
