Stopped Endless Scratching

Challenging outbreak of fleas...never before so many fleas. Tevrapet stopped the scratching and let the dogs (and me) sleep without interruption.

We have used this product on our golden and he has fleas! We even bathed him in dawn dish soap when we discovered him chewing constantly. Our yard has been treated as well. They are on him and he is chewing himself bald on his hind end and legs!

Unsure about this product

She started having seizures a few hours after use and several each day after- she’s on medication for it and only usually has a seizure about 2-3 times a year- I

She started having seizures a few hours after use and several each day after- she’s on medication for it and only usually has a seizure about 2-3 times a year- I believe this flea medication is triggering one or two every day now- I should have just gotten the once a month chewable

Highly do not recommend

This product didn’t work at all. Had to go spend another $60 and then some for topical after purchasing this because it didn’t work at all.
