Expert Perspectives on the Safety of Round Up for Dogs

Dr. Emily Hartwell (Veterinary Toxicologist, Canine Health Institute). Round Up contains glyphosate, a chemical that can be harmful to dogs if ingested or exposed in large quantities. While incidental contact may cause mild irritation, prolonged exposure or ingestion can lead to gastrointestinal upset, lethargy, and in severe cases, organ damage. Pet owners should exercise caution and keep dogs away from treated areas until fully dry.

Michael Langston (Environmental Toxicology Researcher, GreenSafe Labs). From an environmental toxicology standpoint, Round Up’s active ingredients pose a risk to dogs primarily through dermal absorption and ingestion. Although glyphosate is considered moderately toxic, the formulation’s surfactants can exacerbate adverse effects. It is advisable to follow strict application guidelines and prevent dog access during and immediately after treatment to minimize health risks.

Dr. Sandra Kim (Veterinarian and Clinical Pharmacologist, Pet Wellness Center). Clinical evidence suggests that dogs exposed to Round Up may experience symptoms ranging from mild skin irritation to more serious systemic toxicity depending on exposure level. Immediate veterinary consultation is recommended if a dog shows signs of vomiting, diarrhea, or unusual behavior after contact. Preventative measures and awareness are key to protecting pets from potential harm.
