Living with an itchy dog is no fun - but being an itchy dog must be worse! Atopy affects around 1 in 10 dogs to some degree. In dogs the condition can cause a variety of signs: skin disease, runny nose, itchy eyes and (very rarely) asthma. If your dog persists in licking its feet or has recurrent ear or skin infections, it may have atopy. As a general rule itchy skins do not resolve without treatment; so if your dog is scratching an early visit to your veterinarian is advisable. Itchiness is not normal nor is it a habit.
