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

Stopped working.
This product worked for a while. I used it for one summer and it worked so bought it this year as well. First box worked. Bought another, and did not work. Not sure why it stopped working. My dog now has fleas that I need to figure out how to get rid of.

Great Product
Live in south Texas and was in need of an effective flea product. Used nexgaurd for a few months and it wasn’t doing anything for my dogs. So I have been using this for 3 months now and the itching has stopped,no fleas ,and no biting. Very pleased with product.

Best flea prevention on a budget
I used to be big on the “only buy flea meds from the vet.” But, after struggling financially and doing some research, I decided to try this. I haven’t gone back since. This product is effective, easy to apply and, the dogs don’t seem to mind it. I highly recommend this brand to anyone.

Made my dogs sick
Made both of my dogs sick and they still have fleas. After using this product for 6 months I finally realized that every time I put this on the back of my dogs necks, they got really sick.
