About This Item

Details

  • Provides dogs and puppies (12 weeks of age or older) with necks up to 23” with one year of continuous protection from fleas, flea eggs¹, ticks, and mosquitoes¹.
  • The all-weather time-release collar goes on easily, providing a secure, comfortable fit that shields them from pesky bugs come rain or shine.
  • The adjustable collar can be trimmed to fit any neck size up to 23” (of dogs 12 weeks of age and older) and contains the same active ingredients as Tevrapet® Activate® II Collar for dogs.
  • Just place the collar around the dog’s neck and secure it in place, keeping two fingers between their neck and the collar to provide ample slack and ensure the most comfortable fit. Buckle the ends closed and trim the excess length beyond the buckle.

He hated taking meds and the very last one he took he threw up and got really sick. Emergency room bill was $750. His collar works great and he no longer has to take meds. He gets an annual heartworm shot instead of that med as well. So much easier and effective.

Good value

Does not irritate Jeannie's neck, and seems to be keeping flea numbers down. But a few of the pests still persist.

I bought this for all my cats and dogs and they all still have fleas. It doesn't work, disappointing.

The price was good, the product not so much. They are kind of thin and flimsy the first one broke within 3 days. The second one is still in its pouch. I haven't used it as I know it's going to end up breaking too. I will keep it for an emergency if they get the fleas.

Strong chemical smell

I haven’t had this collar on my dog long enough to tell if it works yet. BUT- it has such a horribly strong chemical smell that I’m not sure it’s going to stay on

I haven’t had this collar on my dog long enough to tell if it works yet. BUT- it has such a horribly strong chemical smell that I’m not sure it’s going to stay on long enough to find out. I cannot let the dog be near me like she usually is. Very disappointed and will not purchase again. Money wasted.

I've had this on my dogs for about 3 weeks now and while the fleas are fewer, it has not repelled any. My poor pups are crying because they are so itchy. I would not buy this.

Actually seems to work.

I can't use the mainstream collars due to side effects and the brand I used for years was discontinued. After trying others that smelled awful and just didn't work, this has been a nice surprise. The first week I noticed a couple of attached ticks but decided to leave it on. Now I get more ticks off of me than the dog. It has lasted 3 months and appears to be working well . The scent is not objectionable and I am very sensitive to strong odors. So far, I am pleased and plan on using it thru out the year. I think it is very reasonably priced

It takes a while

It doesn't work instantly it takes a while, my dog can be outside playing on the grass and won't have any fleas.
