To our Canadian Dog Lovers

For more than one year we offered FleaHex in Canada. This product has been praised as highly effective and we have received zero reports of adverse effects from our customer reviews and feedback.

Unfortunately, we have recently received a letter from Health Canada that we can no longer offer FleaHex in Canada, despite the increasing numbers of fatalities and side-effects caused by conventional flea products. We hope this situation is only temporary but, at this point, the product has been classified as an insecticide and will require a year-long, or longer, approval process without any guarantee it will be successful.

We will continue to work with the government to come to some resolution for our Canadian customers eventually, however this process may take a very long time.

Thank you for your understanding and patience.

Dr. Peter Dobias and the Natural Healing Team

The FleaHex® Story

“Our Journey to a natural flea solution.”

“We love dogs and understand how much your dog means to you. We trust that FleaHex® and our other natural products will help your canine friend live a long, healthy and happy life.”

  • Why Natural?
    Based on EPA reports, conventional flea products have caused serious side-effects and we believe your dog deserves to be protected and treated better. FleaHex® is made from all-natural ingredients, herbs and essential oils and has a pleasant, mild herbal scent.
  • Tested in Hawaii
    It is often said that Hawaii is the “flea capital of the world.” We developed and tested in Hawaii to ensure efficacy where fleas flourish.
  • Zero Side Effects
    FleaHex® was introduced in 2015 and there have been ZERO reported side effects or incidents to date.
  • Our Guarantee
    We are confident that FleaHex® will work for your dog and offer you a 100% satisfaction guarantee.

In the following section we will briefly cover some of the studies done on the toxicity of traditional, drug-based flea control products.

A report by the NRDC found that the riskiest pet products contain a family of poisons called organophosphates, or OPs. OP pesticides, which are derived from nerve gas, interfere with nerve signal transmission. Since the neurological process they attack is common to insects, humans, dogs and cats, they can harm more than just fleas and ticks. Over a four-year period ending in 1996, poison control centers logged some 25,000 cases of children under age the age of six who were exposed to OP pesticides from flea and tick control products. Hundreds of children were hospitalized.

Flea and tick topical product toxicity levels 500 times higher than EPA recommendations

Over 50,000 percent more than EPA recommended toxicity levels

According to a 2009 report by the NRDC - Domestic animal flea and tick shampoos, collars, sprays, and dips can expose adults and children to toxic pesticides at concentrations that exceed by 500 times -- 50,000 percent -- the safe levels established by the Environmental Protection Agency.
