After half a year of fleas, switching to this product completely got rid of them!
Cannot recommend enough! I live in the middle of the mountains next to a large national forest. There's deer, beer, turkey and all sorts of wildlife moving through my yard and in the woods year round, visibly agitated by fleas. My dog of 14 years finally got fleas (she's an inside dog with lots of outdoor playtime), as I've been thorough with checking her fur during brushings and baths. I usually just give her monthly flea baths which sufficed, but after a neighbor clear cut their property I've had an influx of wildlife on my property and I think that contributed to my dog getting fleas, I'm not sure. Regardless, she had fleas and they became an irritating presence within my home. Unfortunately, there's plenty of carpet for them to hide in and lay eggs. Yuck! I tried everything to get rid of them! Carpet powders, flea baths (different brands), furniture spray, cheap flea drops.. nothing worked. I battled with them for almost 6 months!! My poor dog was waking up constantly scratching and pacing back and forth throughout the house. I felt like an awful parent and was going crazy before finally deciding to look into the more expensive options.. Now, considering how much I spent on cheaper alternatives that didn't work or get rid of the problem at the source, I really wish I would've went straight for the higher priced option first. Within a matter of weeks of using this product I saw a quick decline in fleas inside the house and on my dog. Within one to two months, they were completely gone! I was in complete shock. I cannot praise this product enough. Maybe it's so effective on the fleas in my area since I live in the rural countryside where they're not used to it, as opposed to city fleas, so your mileage may vary. But for me this was a miracle product and I will be using this as a preventive measure in the summer months, with a periodic dose in the winter. If you struggled with fleas for months and months like I have, you will know the complete relief that comes with a flea-free home. Don't skimp! It may be more expensive than the alternatives but trust me with I say I tried all of them and nothing came close to getting rid of them, whereas this treatment was so fast and effective I was left nearly crying when I saw my sweet dog sleeping soundly through the night. :)

Thankfully, it works!
We have fought fleas on all fronts in our hot and muggy rural area. Frontline and the generic version- useless. Sprayed the land, treated our home, sprayed our dog with an additional temporary spray. This is the first time we've ever had such problems. Dog was constantly scratching, visible fleas and flea dirt. Flea comb simply full of mature fleas and flea dirt. Two vet visits in which we were told the next step was a yearly and expensive treatment. Thankfully, found this on Google as vet recommended. Bought a dose here. It arrived yesterday and we immediately applied as directed to 15 lb dog. He was fine upon application. No major problems afterwards but did began to claw himself aggressively and nip at his paws. Found those relatively minor results on the carton safety data and saw no reason to be overly concerned. I did give him the dose of antihistamine as prescribed by our vet. I think the fleas were 'abandoning ship'! He became drowsy within about 40 minutes settled down and slept soundly all night. No raw spots or other problems today but he looks like a newer, improved dog today. He is basically white. Today there were no visible fleas or flea dirt. Yes! So glad we found this product, all I will buy again! Great customer support because I called the # on the product box today just to check his reaction. They were great.

Does not kill fleas
I have used these for years and the last 3 months supply has been a disappointment they are not killing the fleas at all. My babies still have fleas crawling all over them after application. I will no loner be buying this product.

Watch for burns when the weight is close between doses.
After nexguard plus was found to be causing my frenchie liver and pancreatic issues for almost two years, I decided to try this instead. Caused skin burns on my 27lb frenchie... got the smaller breed dose after that and monitored his skin closely after and it was fine. Just beware and watch their skin after application when the weight is close between doses. I went by the weight for the dose and the smaller breed dose did not cause the burns and is still effective treatment.

This treatment works
I’ve tried other brands in the past with less than great results . I’m happy to say my little guy Johnny Rocco is now flea free and this was confirmed by his mobile groomer who bathes him cuts his hair and would see fleas if they were on him . On his recent groomer experience she told me nope no fleas not even dead flea eggs . Count me as a happy customer with this flea treatment .

Works so, so. Not very well.
Effectiveness, maybe 60%. Our dog is an indoor dog that we walk for potty breaks. The area surrounding our home is sprayed by a pest control service. I will not buy this product again.

I use this and it works for all 6 of my dogs.
I have used this for years. You apply to their back. It is easy to use and not messy. My dogs have not gotten fleas or any other bites. I will continue to use. It works well and lasts for the month if not longer. The dogs do not notice it on them. Do not scratch or try to lick it. Great for the price. I have not noticed any side effects.

Buena relación calidad-precio
En la caja vienen 6 pipetas, como se indica en la descripción: 4 de ellas vienen en el sobre hermético de la propia caja y las otras 2 vienen sueltas (la caja realmente es de 4). Contenta con la calidad de Advantix, no me arriesgo a probar con otra marca. Muy recomendado por la relación calidad-precio.

llego en Fecha
Llego en la fecha comprometida. Aparte traia un pequeño detalle, que es de agradecer, con unas chuches para el rey de la casa, para que el "trago" de la desparasitazación sea más dulce.
