Questions & Answers

7 Customer Questions

the products above are they ok to use on dogs as well

Answer by Chewy • May 23, 2018
This product is also gentle enough for dogs.

I seen someone says they used for their goats. So this is safe for mini fainters? 3 months old?

Answer by Chewy • Jun 04, 2020
Farnam Repel-X Horse Insecticide & Repellent is EPA registered for horses and dogs. It is not recommended using on goats. It's recommended to speak with your vet to find which treatment would be suitable for goats.

is it oil base or water base?

Answer by Chewy • Apr 26, 2019
This product is water-based.

Is this safe to use in combination with a topical treatment?

Answer by Chewy • Apr 02, 2019
Full-strength preventatives are intended to be used alone. We encourage speaking with your vet before combining pest preventatives for the safest opinion.

Finding an affordable and effective fly spray

It is more effective than the last two I tried, but I still had to spray legs twice. The deal of getting the second bottle for 1/2 price was great.

Works, without being too harsh.

This has been my go-to fly spray for over 15 years. It is incredibly effective without being too harsh for my thin-skinned thoroughbred. Does a great job repelling

Repels flies from my dog.

This was my second purchase of this item. Especially helpful last Summer. BUT because of conflict about appropriate use was raised during a review on Chewy, I checked

This was my second purchase of this item. Especially helpful last Summer. BUT because of conflict about appropriate use was raised during a review on Chewy, I checked with Vet today. She agreed the product would be safe for dogs as well as horses, but cautioned that would be for outside use only. Not intended that it’s on your dog who lives closely with you and family in the house. Might explain my dog’s digestive problems, and mine. Waiting for my dog’s fecal tests.

It protects against multiple biting insects

My horse actually enjoyed getting sprayed! I felt better knowing it protects against many insects.

Only thing that worked

We tried everything to keep the flies off our outside dog. This product is the only thing that really works and has longevity.
