Exercise is essential for helping your dog live a healthy life, but the right amount matters just as much as the activity itself. Both over- and under-exercising can affect your dog's physical and mental health, especially their joints. Finding the right balance depends on your individual dog's age, breed, size, and health status.
What Happens When Dogs Get Too Little or Too Much Exercise
Under-exercising impacts a dog's health in much the same way it does for humans. Regular exercise helps maintain joint and heart health, keeps your dog at an appropriate weight for their breed and age, and builds muscle mass that supports the joints by reducing the load they carry. Without enough exercise, dogs are at higher risk of developing issues in all of these areas over time. Exercise also serves as an important mental health outlet — walking outside provides stimulation that positively affects behavior.
Over-exercising carries its own risks. Dogs can push past their limits, and rigorous activity can cause joint injuries. In obese dogs, intense exercise can lead to heatstroke or heart attacks. If your dog is overweight, do not start them on an intense exercise routine — especially if they have not been exercising regularly. They need to build strength gradually, combining an appropriate level of activity with a healthier diet and guidance from your veterinarian.
Exercise Needs by Age
Your dog's age is one of the most important factors in determining how much exercise they need. A puppy and a senior dog have vastly different requirements.
Puppies
Puppies over 10 weeks old tend to have high energy but tire quickly. They must be fully vaccinated before exercising outdoors. Short bursts of exercise and play throughout the day are more appropriate than one long outing — think brief walks and play sessions followed by naps. Play dates and visits to the dog park are valuable for socialization, helping puppies learn how to interact with other dogs during this critical developmental period.
Adult Dogs
Adult dogs generally know their own limits and can exercise with ease. Their joints and bones are fully grown, and they have typically developed preferences for the types of exercise they enjoy — whether that is walking, swimming, playing, or something else. This is a good stage to introduce variety and try new activities together. Adult dogs can handle longer, less frequent exercise sessions compared to puppies (though the specifics depend on breed). As dogs move through adulthood, they may begin to benefit from a joint supplement to help maintain mobility for the long term.
Senior Dogs
Senior dogs benefit from gentler forms of regular exercise such as short walks, gentle play, and light swimming. Comfort should be the priority — if your older dog is limping or is significantly slower than usual, it is time to re-evaluate what they need with your veterinarian. Senior dogs should still exercise regularly, as movement helps prevent joints from stiffening, but they should never be forced into activity they are resisting.
A joint supplement designed for dogs with stiffness can provide additional support during this stage. YuMOVE Advanced Vet Strength Chews are formulated for dogs with significant stiffness, while YuMOVE Tasty Health Bites offer preventive daily support.

Exercise Needs by Breed
Your dog's breed tells you a lot about how much and what type of exercise they need. Some breeds are far more athletic than others — a Labrador Retriever and a Bulldog will have very different needs and abilities. Flat-faced (brachycephalic) breeds in particular require careful attention, as extended walking without breaks or exercise in hot weather can be especially difficult for them due to their restricted airways.
Size also plays a role. Larger dogs tend to find rigorous or high-impact exercise harder than medium-sized or more agile dogs, and over-exercising large breeds can contribute to joint problems over time. Understanding your specific breed's tendencies and limitations helps you set an appropriate exercise routine that supports their health without pushing them beyond their capacity.
