There are several ways to protect the health of your dog’s skin and coat if you live in a large city: Keep your dog clean: Regular baths and grooming can help remove dirt and pollutants from your dog’s coat and skin. Protect your dog from the sun: Dogs with light-colored or thin coats may be more susceptible to sunburn. Use a dog-specific sunscreen or keep your dog in the shade during peak sun hours. Keep your dog hydrated: Dry skin can lead to flakiness and itching. Make sure your dog has access to clean, fresh water at all times. Use a high-quality dog food: A healthy diet can help keep your dog’s skin and coat in good condition. Choose a dog food that is appropriate for your dog’s age, size, and activity level, and that contains high-quality ingredients. Consult with a veterinarian: If you notice any changes in your dog’s skin or coat, such as dryness, flakiness, or excessive shedding, it is important to consult with a veterinarian. They can help diagnose any underlying problems and recommend treatment options.
