Fleas can cause irritation to your pet. In some cases, fleas can cause Flea Allergic Dermatitis (FAD) which is a hypersensitive reaction to flea bites where your pet should see a vet. Fleas may also transmit tapeworms to your pet. Tapeworms live inside your pet's intestines, causing irritation, tiredness, weight loss and tummy upset.
