Determining the underlying cause of the scratching is essential to solving the issue effectively. A visit to a veterinarian is recommended to rule out any medical conditions, such as allergies or infections. Bathing your dog with a medicated shampoo and using an anti-itch spray can provide temporary relief. A diet rich in omega-3 fatty acids can also help improve skin health. Regular grooming, including brushing and trimming long hair around the neck, can reduce irritation. It is essential to address the issue promptly to prevent complications from excessive scratching.
