November 24, 2019 (San Diego’s East County) -- Dear EarthTalk: Is it true that lawn chemicals can cause canine cancer, and if so, how can I protect my dog? --Bill W., Ithaca, NY
Unfortunately, the answer may very well be yes. A 2012 study published in the peer-reviewed scientific journal, Environmental Research, found that exposure to certain lawn care products, such as the nearly ubiquitous herbicide 2,4-Dichlorophenoxyacetic acid (2 4-D for short), increases dogs’ chances of developing Canine Malignant Lymphoma (CML) by 70 percent. When ingested repeatedly, 2 4-D acts as an endocrine disruptor, mutating a dog’s white blood cell count allowing malignant tumor cells to replicate unchecked. While obviously worrisome for dogs and those of us who love them, the implications for people aren’t good either, given the similarities between the onset of CML in canines and non-Hodgkin’s lymphoma in humans.
