Buying advice

When choosing a flea spray, consider your dog's skin sensitivity, the severity of infestation, and whether you prefer natural or chemical ingredients. Sprays with Insect Growth Regulators (IGRs) prevent reinfestation. Always test a small area first and avoid contact with eyes and mouth. Reapply as directed, especially after bathing or heavy rain.
