I use to be one of those super paranoid Pet Parents and I use to put the pharmaceutical anti-flea and tick medication like clockwork, every month on the dot. I never missed a date. We use to use Nextguard and Sentinel and like a regular consumer, I never really thought about how it worked, I just knew that it did. It was when my foster pup couldn’t tolerate the medication because of his liver disease that’s when I started thinking more about it.
According to Dr. Cathy Allinovi, DVM, “…the safety testing procedures for these products were not were not sufficient for these chemicals.” She also mentioned that the active ingredients of the newer insecticides are whats known as Isoxazoline, therefore a flea/ tick must bite your pet before it contacts the chemical. If the flea does not bite, it does not die. She goes on to mention the following side effects of more common chemical insecticides…

According to Dr. Deva Khalsa VMD, CVA, FBIH, “…evidence now shows both the active and some inactive ingredients in spot-on preparations have been linked to serious health effects both in laboratory animals and pets.” She further states that Dr. Dobozy of the EPA’s Pesticide Division has found fipronil (active ingredient of Frontline) remain in the pets system and had the potential to disrupt the nervous system and thyroid. Furthermore, test on laboratory animals resulted in the following: thyroid cancer, liver toxicity, kidney toxicity and convulsion.
This information is from, The dangers of flea and tick products — also discusses more chemicals used as active ingredients such as Imidocloprid and Pyrethroids (permethrin)
Imidocloprid side effects include: thyroid lesions, liver toxicity, damage to liver, heart, lungs and spleen.
Pyrethroids side effects include: brain damage, heart attacks and seizures. Permethrin is also carcinogenic causing lung cancer and liver tumors.
Dr. Khalsa also mentions that the best alternatives to chemical pesticides is prevention. “Healthy dogs and cats are not good hosts to parasites”
Here are what we use for our pack. We have 3 dogs and 4 cats and this is the treatment option that we have decided to move forward with.
I want to repeat what Dr. Khalsa mentioned, “Healthy dogs and cats are not good hosts to parasites.” So please keep your dog healthy in terms of exercise and nutrition. Feed them quality proteins instead of commercial dog food and make sure you walk them daily.
