Just like with any breed of dog, when it comes to bath time, there are certain tools you will need. This is to ensure that your dog’s coat is cleaned properly. When it comes to bathing a King Charles Spaniel, you will need the following: Soap – You’ll need to use a mild-smelling soap. Some brands of dog shampoo contain chemicals that may irritate your dog’s sensitive skin. Towels – Use soft towels made especially for pets. Use one for each part of your dog’s body. Don’t use paper towels or cloth napkins, these could leave marks on your dog’s skin. Or irritated and dry out your dog’s skin. Brushes – Use a brush designed specifically for dogs. Choose a bristle type that fits your dog’s coat well. You can find brushes for different breeds online or at pet stores.
