The Clumber Spaniel has a life expectancy of 10-12 years. Males typically weigh 29-34 kg and stand 43-51 cm tall, while females weigh 25-29 kg and are 41-48 cm tall. They are resistant to moderate cold but sensitive to high heat, possess a high energy level, and have a smooth, dense, and soft coat, primarily white with orange or lemon markings. Hereditary diseases include hip dysplasia, eye problems like entropion, and breathing issues due to their head structure.
