Some of the most common skin disorders in dogs include bacterial skin infections, environmental allergies and parasite allergies. Bacterial skin infections are among the most common skin disorders. Skin problems in dogs are more common during the warmer seasons, which is when seasonal allergies, insect bites and other allergic symptoms are more likely. Itching is one of the most obvious symptoms if your dog has a skin condition, but it’s difficult for pet owners to determine exactly what’s irritating your dog without a full veterinary examination. Symptoms of dog skin conditions can include skin sores, skin lesions, dry skin, flaky skin, scaly skin, rashes, lumps, redness, dandruff, bumps, intense itching, excessive licking, excessive scratching, hair loss, and bald patches. Skin symptoms in dogs – such as itching, rashes or bald patches, could be an indicator of an underlying cause or health condition that hasn’t already been diagnosed by a vet or vet nurse. A dog’s skin condition can range from mild to severe.
