How much exercise a dog needs depends very much on the individual dog. The breed, age, health, and even the individual dog’s personality all need to be considered. A puppy, for example, will want to exercise and play but will require regular rest breaks. Still, intensive exercise is bad for their bones and joints, so it needs to be avoided. In contrast, an older dog may have mobility issues or problems with hearing or vision that means sticking to shorter, familiar routes or, in some cases adopting an exercise routine that they can do indoors. For most dogs, though, the key is making sure they get regular exercise interspersed with rest breaks and going at the dog’s own pace.
