6 MONTHLY DOSES OF FLEA TREATMENT FOR DOGS: Each pack of TevraPet FirstAct Plus contains six (6) topical applicators of waterproof flea medicine for dogs that instantly begins to kill and control fleas and flea eggs, larvae, ticks, and chewing lice – and provides continuous protection for up to 30 days after each application
VET QUALITY FORMULA, EASY TO USE: FirstAct Plus uses Fipronil and (S)-methoprene – the same safe and effective active ingredients as Frontline Plus for Dogs. This powerful formula starts to kill fleas and ticks within 24 hours. Simply apply the applicator to the skin on the back of your dog’s neck and the formula will migrate through the skin providing whole-body protection
THE SAME ACTIVE INGREDIENTS AS FRONTLINE – FOR FAR LESS: It’s worth repeating: Just like Frontline Plus, FirstAct Plus’s powerful active ingredients REPEL and KILL fleas and ticks on contact and stop reinfestations. At TevraPet we firmly believe you shouldn’t have to pay the “Brand tax” to protect your dog, and we are committed to providing affordable, veterinarian quality solutions without sacrificing an ounce of safety, effectiveness, or reliability
BREAK THE FLEA LIFECYCLE – KICK THE ITCH: Unlike other flea and tick repellents that only temporarily suppress pest activity, FirstAct Plus for Dogs kills flea eggs and larvae to stop infestations dead in their tracks and breaking the flea and tick life cycle. With FirstAct Plus your dog spend his or her time enjoying life both indoors and outside – no more worrying about biting bugs
QUALITY ASSURED, RESULTS GUARANTEED: Every dose of FirstAct Plus is produced at our facility in Germany to the exacting standards we demand for our own pets, and rigorously tested for quality and potency. Every single dose we sell is backed by the TevraPet guarantee – if you (or your dog!) are unsatisfied for any reason simply contact us for courteous assistance and a no-questions asked refund

Quality Product
This product is less expensive than Frontline, but has worked well on my 3 Life Stock Guardian dogs. They are exposed daily to ticks and fleas. I have found no fleas or lice and only dead ticks on the dogs.

My absolute go to for fleas
I have tried ALL the “generic” Frontline on here. This is by far, the best one. The Amazon brand made several of my cats lose fur and break out. Smelled absolutely horrible like a fishy scent. This one did not.The others only keep fleas off for about 2 weeks and did not kill eggs because I kept finding teeny ones. Like fresh hatched.This one worked and killed all fleas. Lasted a month and did not smell strong. Will keep buying. Just like Frontline at a better price.(

Works at first, but then it doesn’t.
It seemed like it worked at first.. the pets were itching more within the first several hours and by the next day, the itching had stopped. We had a great first couple of days, but by the end of the first week, the itching started again & upon further inspection- all of the pets still has fleas.I understand that it’s normal to still see a flea or two on the pets bc they may be a new arrival and/or hadn’t come in contact with the product, etc.. but the fleas we are seeing were in the usual areas on our pets that fleas typically like to hang out (like on their necks, stomachs, near the tail, etc), all the time. Also, our pets started itching again..I know that with Advantage/tix, sometimes it takes a few weeks for the product to distribute throughout their fat or something like that, but from what I’ve read, this product is in the hair? So I don’t know.I’m going to dose them again in a couple of days bc it will have been 2 weeks since the first dose. I’ll update with our findings after then!

No fleas, saves money.
We buy largest size for our chihuahua and put one vial in glass ampule with lid. Use 0.5 ml per month which is the dose in the small dog size. All sizes are the same ingredients and strengths. Saves a lot of money. Keep a note book of treatment dates.
