Whether you want to take your pet on a long walk in the park, on vacation, or just outside to do their business, you run the risk of exposing them to a wide range of biting insects every time they go outside. Fleas, lice, ticks, mosquitoes, flies, gnats, and other nasty bloodsuckers don’t just leave itchy welts behind, as they are all capable of transmitting horrible diseases that may have long-term effects on your pet’s health. Keeping a bug repellant on hand for your pet is a smart move, but it’s up to you to research the best formula to protect the cats and dogs in your care from bug bites.
