My dog, who is treated for fleas 5 times a a year, and therefore "used" to flea products, had a HORRIBLE reaction to this flea treatment. My dog never had any bad reactions to Frontline or Advantage, but Vectra 3D is another story. Within 12 hours of application, my dog started itching like CRAZY at the application spots. But worse, 24 hours later, my dog started having panic attacks, panting horribly, acting extremely hyper active, scratching herself psychotically, etc. It was getting very scary. I bathed her to get the remaining Vectra 3d off of her immediately. I will NOT use this product again and I do NOT recommend Vectra 3D to anyone!

I looked up more reviews on Vectra from other websites, and apparently a lot of people are having this reaction and much, much worse reactions, even death.

Also, DO NOT USE THIS IN HOUSEHOLDS WITH CATS! VECTRA 3D IS EXTREMELY TOXIC TO CATS and even SLIGHT EXPOSURE CAN BE FATAL TO CATS.

My cats have been clawing at themselves for a month after we gave them this medication. Nothing helps to make it stop. The manufacturers should be sued!

Having terrible reactions with my 8 lb.toy pom.

Took her to the vet today - he spent almost an hour with us and didn't charge.

(Probably because I purchased Vectra 3D from them.) I'm giving her 1/4 of 25 mg of benadryl twice a day, and bathing her with Dawn.Bad, bad treatment - it's an insectide - and we all know about that.

I applied veternarian prescribed Vectra for cats to my moma cat and her 3 pound kittens last night. The effects were horrible...

Within 20 minutes they were all scratching like maniacs and I thought at first the Vectra was just working because i could see the fleas dying. However one of the kittens started closing her eyes as though something was burning her eyes even though as directed I appied it only to her upper back. An hour later it was worse as all 4 cats, moma and kittens were acting like they were losing their minds. The one kitten had started drooling by then and all of them were having severe muscle spasms in their legs and arms. It was late so I called the local animal emergency hospital to ask what to do and was told, "Vectra is a perfectly safe product and maybe your cat and kittens are just acting our because they have something foreign on their skin". I then asked, if the something foreign on their skin should cause them to loose their bladders and bowels? Was drooling and heaving normal with the uncontrollable scratching as though they had a toxin on them normal? The woman on the phone then quoted me a price to come in to emergency when I asked will you please just tell me what to do. She suggested washing the area I had applied the Vectra with a mild detergent which I did immediately after hanging up. The profuse itching and twitching stopped after I used a wet wash cloth with dishwashing liquid followed by another wash cloth with only...

Clearly this product, Vectra has issues with toxicity. I have no idea how Vectra got past the FDA in testing or release to the general public except for the normal way that drugs make it, with complete oversight. I am worried that this one dose has done some permanent harm to my 3 month old kittens and their mother. Also the moma cat has not hardly come near her babies all day and night which is very unusual for her as she is a very attentive moma cat. I'm so angry and disturbed that I applied a vet prescribed drug that has harmed the little ones and their mother.

Whoever is reading this, PLEASE DO NOT USE VECTRA ON YOUR ANIMAL!

I think an animal is supposed to be 8wks old for Vectra 3-D. Whoever advised you to apply it to 3lb kittens is a ***.

I used vectra on 3 of my dogs.The boxer and lab seemed to have no reaction but my 7lb you poodle is in misery.

After 24 hours post application he began with hyperactivity, the. Had loose/bloody stool in the middle of the night, I also noticed hair loss and his back twitching at the site of application. The worst is the constant anxiety. The poor guy continues jerking around to his tail but then does nothing, just circles.

He wants me to hold him constantly.

I have given him 2 baths with dawn and also tramadol to help him relax.This medicine needs a black box warning!!!!!

I just checked for info on Vectra 3D online as my pug has been scratching and acting really weird, whining, super needy, flapping his ears so bad that I thought maybe he was infested with fleas or something and couldn't remember if Vectra covered fleas.Found this and many many other websites with stories of dogs having bad reactions to this medication.

I don't have Dawn, but I used body wash for tonight and I'll get Dawn in the morning if he's still acting crazy.

He's little and it seems like, from the stories that I have read, that little dogs seem to be the most affected.My big dog (Boxer/Pitbull mix)is totally fine and he got Vectra also, but yeah, I'm going to be calling my vet in the morning and getting back on Frontline.

Fleas have become immune to Frontline/Frontline Plus New product called Frontline Gold is on the market through vets only. It now contains one of the ingredients in Vectra 3D.
