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.

Great product

My dogs already had fleas and ticks on them. I put the flea and tick spot treatment on them and the fleas and ticks disappeared in a day or two. Works great for about a month keeping them off. I used this product last summer also with great results

Effective product

I have used this product on my family large dogs and my personal dog . The product itself works very well , but on my dogs it was leaves a white residue on them. I have attempted to remove the spots with no luck

Great backup

The ticks are really horrible this year. Usually a Seresto collar takes care of fleas and ticks for my dogs but this year they were still getting ticks here and there. I purchased this product and used as directed but left the 3 month old Seresto collars on. No fleas and only one tick after a month

great product

This works great on my 90 lb lab! Never seen a flea on him! I put it on him every month. He hasn’t had any negative side effects from it.

Zero effect

Didn’t provide any relief or protection. (Didn’t seem to bother their skin either if that’s a worry of yours)
