When you are ready to give your springer spaniel their first haircut, it is best to take them to a professional groomer. This will ensure that the haircut is done correctly and that your dog is comfortable during the process. The groomer will be able to assess your dog's coat and recommend the best style for them.
After your dog's first haircut, you will need to continue to brush their coat regularly to keep it healthy and looking its best. You may also need to take them to the groomer for regular trims every few months.
