A new study by the Environmental Working Group in Washington D.C. found fluoride levels 2.5 times greater than permitted for human consumption in eight out of ten dog food brands tested by an independent lab.

“While scientists have not determined how much fluoride is safe for dogs,” the EWC report states, “they have found that people who consume excessive fluoride often develop mottled teeth (dental fluorosis) and weakened bones, leading to more fractures. High fluoride consumption is also associated with reproductive and developmental system damage, neurotoxicity, hormonal disruption, and bone cancer.”

Although the study does not identify the brands by name, the EWG recommends avoiding dog food that contains bone meal and meat byproducts.
