My dog & cat has never gotten flees since I started this medication on both. Rohan has extremely white short hair & pinkish skin . The 1 time he did get flees,he wasn't medicated) was 11 yrs old & they just came from inner city dog play area. He took them home & Kate got them. She's long hair. But since I started both on meds, more itch flees. Also, usually the bigger the dog, the bigger the flee medicine. Not so w this brand. All sizes cost the same

Easy to apply

Open the package and easily apply from the top of your dogs neck down the lower part of the lower back. I suggest you use latex gloves to blend in liquid.

Waste of money

Did not work... at ALL. None of my pets, dogs or cats, as we purchased both, got relief from fleas. Not even for a day.
