Glyphosate is the most frequently used herbicide in the world because it is so effective, but it has been linked to cancer. As a result, we believe it is equally detrimental to dogs, especially if they come into touch with it frequently. Glyphosate is "possibly carcinogenic to humans," according to the World Health Organization. It is safe to use, according to the EPA, as long as it is used exactly as directed on the label.
