Fleas are more than just an annoyance for cats and dogs – they can cause skin disease and spread infectious or parasitic conditions, some of which can affect humans. In some dogs, fleas trigger flea allergy dermatitis (FAD), an intensely itchy skin condition that can lead to hair loss and infections. Even a few fleas can cause severe irritation in affected dogs, making year-round flea control essential.
Pets usually pick up fleas from their environment, rather than direct contact with other animals. Fleas can be found in dog parks, backyards, beaches and even on walks. Spotting them isn’t always easy, as they move quickly, and infestations often start before you see adult fleas. In fact, adult fleas make up only 5% of the population — the remaining 95% (eggs, larvae, and pupae) hide in carpets, bedding and furniture. Since fleas reproduce rapidly, ongoing flea prevention is crucial for keeping your pet comfortable and your home flea-free.
