Defy The Fly Dog Collar - 17" to 20" Size Medium

I use this collar for our outside dog. His ears always get chewed up by the biting flys! This definitely helps.

Works great, better than ugly pink fly paste or sprays. Just can't get large size anywhere!

I purchased this in hopes of having a constant fly repellent that I did not have to keep applying to the ears like I have to do with fly spray and fly ointment. When I found out about this collar, I figured I'd give it a try. Even though it said it was not waterproof, I decided to still give it a try. At first it actually did its job and repelled flies, but after a few days, it was clear to see that this would not be a reliable product. I got caught in the rain while walking one of my dogs. The effectiveness completely dropped to the point that it no longer protected him from the flies. If the collar not being waterproof when it is for animals that are usually going to be outside wasn't bad enough, the design of the color is also fragile with both collars breaking before the month was up. I do not see how anyone with outdoor dogs can expect these to last two months. I had recently purchased another herbal repellent collar called Dr. Mercola Herbal Repellent Collar that is waterproof, has its ingredients as part of the collar itself, and supposedly lasts for four months. This new collar sounds like a better, more reliable product.

My dog refused to go out for a walk when the black flies really started biting this summer. She'd dig in and sit down - that is, when she wasn't trying to bit them.I saw this product and thought it was worth a try. Yep! It worked. Put it on the dog prior to a walk, and like magic, the black flies avoided her (at least her face, which was the main problem). I shared this info with neighbors who also walked dogs. We all agreed, we wish there were a collar for us that could do the same!Saved our summer walks!

I have bought these callers for both my dogs for the past three years and always worked very well, this year I have bought three collars and none of them keep the flies away, huge disappointment to come home from vacation and find their ears all bitten up. Not sure if they change the product or what but it’s a very expensive item for it not to work. So disappointing in the company if they are making poor quality items now

This product is awesome for the lazy outdoor-dog owner! My parents are older and unwilling to clean and reapply ointments, sprays, and creams on their outdoor dogs on a daily basis. They needed an easy & lazy way of dealing with stubborn flies during the summer months that bite their dogs' ears. This product couldn't be more perfect for my parents. Its effective, easy to use, and affordable.The only drawback is the super strong Citronella scent. I had to wash my hands several times after putting these collars on the dogs and the scent still didn't wash away from my hands. If the Citronella scent doesn't bother you, this is the perfect product! I would not recommend this for an indoor dog.We will be buying this product every summer!

Absolutely amazing product. NOTHING ELSE WORKS. We tried everything. The house flies outside would not leave our poor dogs’ ears alone. We tried these after trying 20 other things first (garlic, vinegar, ointments, bandages, sprays, fly traps, etc.). Our flies wouldn’t go away and so our dogs ears continued to suffer...... UNTIL defy the fly dog collar. Holy cow. The flies would just buzz around their heads but their ears healed overtime because they weren’t getting any bites. We are still in shock as we’ve been trying to help defeat this problem for YEARS. Our white German Shepherd has had his on for a month and it still works! He ripped our blue Heelers off after 3 weeks, so we had to get her another one, but these things LAST. Can you tell I’m a raving fan? Lol.

My poor girl was suffering from so many flies this year and we tried everything. Her ears had so many bites on them from the horrible flies so I bought this collar and could not believe the difference it made. It seemed to keep the off and also help calm her too. She hated being stuck in the house and now she can be outside without worries. I will definitely buy it again when the smells wear out. It’s great!
