Good value
Good value for the price, but still not sure of the effectiveness. My dogs didn't have fleas before treatment, and still don't, so I guess it works? Regardless, I like that I get 6 doses per box for the same price for 2 of some other brands.

Slow acting but does work!
I have an Australian shepherd and live in dense woodland! I put this on my dog and didn’t get much relief after 30 days. I did notice the ticks were smaller and not bloating on her! Decided to give it a chance and gave her a second dose. The second dose did the trick. She is tick free and I appreciate not having ticks on my furniture and on me!!!

Great product
Why did you pick this product vs others?: Works great for my pups. I am not a fan of giving any more pills than required, so I use the topical. Additionally, my girls have sensitive skin and have experienced very dry, itchy skin from other products. This one contains Aloe, so we haven't seen the skin irritation with the product.

Would not Purchase Again
Did not care for this item - the drops were messy, and did not work well. They also ended up ittitating my dogs skin. I ended up having to purchase another product.

Used to work- now I'm out $80 to the vet.
Hartz used to be a reliable product. Now it's just not. I recently had stray cats start traipsing through the yard at night. They set off the doggie doorbell each night. Stray cats equals stray fleas. Well, I grabbed the orange flea shampoo at WallyWorld and used it. It lasts 14 days, so it should have been fine when this was delayed in arrival by 2 days. Should have been. But it wasn't. Next thing I knew, there was a flea visible running around my dog's leg. He circled a couple of times and I was able to pluck it off and send it down the commode. Long story short- that means that 6 days after application, this should have been working well enough for any flea to be no more. Instead I'm now out $80 for a 3-month Bravecto pill from the vet. Unbelievable.
