Bayer K9 Advantix II Flea, Tick and Mosquito Prevention for X-Large Dogs, Over 55 lbs

I worked as a vet tech for years and this is as good as the high priced products. It is easy to apply. The directions are on the box, and the individual tube. Doesn't really have an odor. Does leave an oily spot for a few hours, but is totally worth the price. It is very effective in killing fleas and keeping them off your pets. Would recommend this because it lasts.

I find this not as effective as another leading brand, but the price is good. I just find that I have to use it more frequently as it wears out faster.

Had a flea jump on me and immediately put my dog in the bath but it was too late. I already had an infestation. I tried another product first with no luck. 2 weeks later at the end of my rope and vacuuming 3x a day 2 flea bombs and 2 flea baths on my dog, with none of it working. I was beyond frustrated so I got this. 3 days later... another clean and vacuum. Washing all the bedding and everything. Fleas gone. THANK YOU!!!!!!!!! I have now subscribed to this product as a prevention instead of just treatment.

This product seems to work the best on both my dogs so it’s my go to. I don’t like the fact that it’s not the healthiest for my dogs though (along with many other types of treatments) so it’s a tough call to make. It’s easy to apply and it DOES kill fleas, flea eggs, and ticks!

It works my dogs haven’t had fleas since
