The Impossible Choice Every Dog Parent Faces
Chemical Treatments: Effective but Risky
FDA warnings about neurological side effects, seizures, and tremors from popular oral medications. The very treatments designed to protect may be causing harm.
Natural Sprays: Safe but Ineffective
Most plant-based solutions evaporate within hours, creating dangerous protection gaps. Your dog might be safe for 6 hours, but what about the other 18?
"I don't want to choose between poison and disease for my dog."
