Important Information

Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 30 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

Good for the Price

We have not noticed a drastic change on our dog with this treatment vs. others, but as far as we can tell for the price it seems great!

Terrible - Made it worse

Used this on my chihuahua mix. Ticks aren't really an issue where I live, so I can't really say whether or not it's effective against ticks. However, after applying my dog's fleas got worse. Incredibly disappointed. It's like it attracts fleas.

Yes it works

I've used these during flea season for the last couple of years. Last year was my first time seeing a flea on my Chi, works as good as the super expensive treatments. No more fleas! I do use the three of them one per month.

short haired chiweenie

Works for my 2 year old. Was oddly surprised. Considering the price. Every Sunday we take him to the in-laws (who use frontline) and my little guy is the only one not having ticks taken off him. Highly recommend to at least try!
