I use this on my large dog's and it works great. No skin irritation and keeps the fleas and ticks away.

5.0 out of 5 stars I always buy this brand for my dogs
Reviewed in the United States on July 8, 2024
I have three large dogs and I find that this particular flea and tick medicine works at a reasonable price. With three dogs, it can very expensive to buy flea meds. I have used this brand for a number of years and I will continue to use it since it works well and is easier for me to get through Amazon at a reasonable price. The subscription helps a lot too since I don't ever want to run out. You even get a discount with a subscription.

5.0 out of 5 stars Favorite flea and tick med.
Reviewed in the United States on May 27, 2024
We have been purchasing the K9 flea and tick for a while for both of our 80lb lab dogs.

I have used other brands, including frontline, in the past and this one is my favorite. I don’t think it has as strong of a smell, my dogs have no reactions to the product, and we rarely ever find ticks on them. We have only ever found 2-3 within a season crawling on them. Super easy to apply. Compared to competitors, k9 tops them.

4.0 out of 5 stars Not as effective as other brands, but better value

I find this not as effective as another leading brand, but the price is good. I just find that I have to use it more frequently as it wears out faster.

This little needle puller is wonderful. I can put more stitches on my needle and pull it through with ease. Love it!

5.0 out of 5 stars Mosquitos are almost completely gone!
Reviewed in the United States on June 1, 2024
In Texas right now it is a soggy mess. With all the recent flooding the mosquitoes have banded together in armies to terrorize everybody and every outdoor pet. My poor dog was being devoured. I have tried several pet friendly options but they only work temporarily. This has been a life saver. I have seen one or two around his snout but they are not trying to bleed him dry anymore. I haven't seen any fleas or ticks and he seems to be very happy and comfortable. Very pleased and will continue to purchase for my pets.

5.0 out of 5 stars Biting flies
Reviewed in the United States on June 20, 2024
My pup had a terrible hot spot on her ears. I used a variety of ointments. It couldn't heal due to flies. 1 day after applying this product I can see a big difference. This was a great purchase. It's a tad more pricey than other topicals, but it repels more than fleas and ticks

3.0 out of 5 stars Does not work on golden retrievers!
Reviewed in the United States on July 4, 2024
I bought this for both of my dogs. One is a short haired beagle mix and the other is a golden retriever. I will say that it seems to have worked great on the short haired dog, but hasn't worked for my golden retriever.
