The Clumber Spaniel is a dog that has been breed for its hunting and agility. These dogs accompany hunters on foot for long excursions into the wooded areas to hunt or just to keep the hunter company. They are work dogs and sport dogs. In other words, the Clumbers are physical dogs and because of this they need to be exercised properly if they are to remain at a healthy weight. If these dogs do not receive enough exercise, chances are good that they will become overweight. This leads to serious health problems! Many of these problems can be overcome with proper exercise.
Because the Clumber Spaniel is a working dog, they are often seen outdoors, running, playing and hunting. Bred to be a physical dog, they are strong but also just as intelligent as other breeds, if not more so. From looking at them, you may be surprised to learn that those low, long and heavy bodies are so physically fit. Yet, they are serious hunters and great for company on long outdoor journeys. Without having this physical activity in their lives, though, they are susceptible to becoming overweight, and quickly.
Do not misjudge this need though. The Clumber Spaniel is a very low key dog. They do not want to spend their days running around the yard with you. Yet, they will enjoy spending time with you on a hike or a long walk. While they do not need to be exercised continuously, they will need walking and some agility training whenever possible. When they have the opportunity to get out into the field, they are going to be persistent, strong and capable. You can train them to be a solid worker for whatever you need them to be, too.
Training the Clumber Spaniel to be well mannered is a good way to give them exercise. You also can train them to do various tasks for you. With their high intelligence, they are good for many tasks. Not training them may have them exploring on their own, in their own way, whether you want them to or not.
Clumber Spaniels need this type of physical stimulation on a regular basis, such as every other day or at least two times per week to remain healthy. A well balance diet is just as important and "people food" should be left out of the mix. To keep your Clumber Spaniel fit, do spend time with him outdoors on long walks or working on agility. They are more than willing to spend time learning what you want from them. Invest this time and attention to them and they will remain healthy for the long haul. Do not do so, and you may find they will become ill very quickly from being overweight.
