Bayer K9 Advantix II Flea, Tick & Mosquito Prevention for Medium Dogs, 11-20 lbs

I’ve tried so many things and nothing was working. I don’t usually have fleas but this year my dogs both got fleas and then brought it into the cats so I’ve tried three or four different products and nothing was working, so I finally got this and it worked perfectly we are finally free of fleas!!!

This treatment is the best ever for our medium size Shepherd. We have a large fenced in back yard with a copse of trees. Deer often jump the fence for a visit and this product is easy to use and the most effective we've found.

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.

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. :)

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.
