Review: This has made a huge difference in the fleas that the dogs have gotten. It is easy to use even when they are unsure about what I am doing to them. It has not bothered either of my dogs. I will keep using this because it actually works.
Review: So my dog is a Jack Russel mix so he has very dense fur. I took him to my parents house with a few acres and noticed before we left that he had gotten fleas from the field! I immediately bathe him and once he was dry, I applied this and haven’t seen a flea since. These are so much more affordable than all of the other brands. I won’t use any other flea drops.

### ⭐⭐⭐⭐⭐ Review
*by J***. on 21 November 2025*

I swear by this flea treatment and feel much more comfortable giving it to me dogs, even a mini 4 pounder *only used half of a tube....still monitor, as opposed to the stronger advantix or similar treatments and it's a fraction of the cost of those or three vent preventative (although that is the best option as it also includes heartworm preventative but this is great if you cant afford the vet or don't have money for expensive treatments. This actually worked better even than some of the more expensive ones I've tried for a really tough case of the fleas on a pomsky (long, thick hair that can't be shaved!). I used this and diatomaceous earth sprinkled in the yard, on my dog (food grade only) and sprinkled on carpet, couches, dog beds, etc. Using an accordian style contraption that came with it and put a light plume into the air, covering everything. Apparently it acts like glass to fleas and flea larvae. You will have to repeat though as it won't touch the eggs.
