Pets suffering from flea bite dermatitis typically present with a history of biting and scratching over their lower back and down the side of their thighs. The scratching can lead to hair loss, sores and secondary infections.
Whilst fleas prefer warmer temperatures, they also well adapted to survive inside during colder months. It has been proven that intermittent biting of fleas can cause pets to become more sensitive to their effects, so it is important to maintain flea control all year round.
