Recommend!

(I previously wrote a review on the Hartz flea comb (5 stars,) for more info check there. I'm too lazy to copy paste, let alone write it again.) I tried the more expensive topical from a different brand... spoiler alert! It didn't work. The fleas basically gave me the finger and said "Hold my beer." I didn't really expect this less expensive Hartz topical to work, but desperate measures and all that. Oh, ye of little faith! I applied it to my 2 dogs (one short hair, one long hair.) The flea battle with my long hair dog has been ongoing. Expensive. Nerve wracking. Within 24 hours of applying the Hartz topical, the fleas were gone. GONE. It's been 2 weeks and doggo's beautiful fur is growing back, he no longer constantly scratches and pulls out his fur so he is starting to look like a dog again vs looking like a male lion. Or hairless cat. I ordered three more. Definitely recommend!

Increased in price but not in quantity or quality, make that make sense! Same product, not happy about that. However, this topical always works for my dogs with a combo of a flea collar. Lasts about a month. 1st couple of days it's very strong and oily but after that it distributes throughout the dogs skin and fur and it is a very effective flea preventative.
