Perhaps your dog has always been a clingy pup. Maybe she is a rescue with some trauma in her past that makes her stick to you like glue. Then there are the dogs that are always after you to play with them. Why can't they just entertain themselves sometimes? We have many reasons for wanting our dogs to be more independent. There is nothing like the joy of watching a nervous dog finally strike boldly out on her own, following a scent or chasing a butterfly. Dogs naturally want to be independent, so teaching them is more like reminding than it is instructing.
The time and effort are worth it, both because it is fun and exciting to see your dog learning to react to new things with independent interest and curiosity, and because the skill of independence will allow your dog a joy and autonomy in life that otherwise would have been lost to her. Dogs of all ages, breeds, and dispositions can learn to be independent, but each dog is an individual, and our patience is the most important element in teaching our dogs to think for themselves.
Next, make a list of everything you can think of that your dog hasn’t done, that you could conceivably do. Be creative. Have you gone to your local stores that allow dogs? Do you have dog-friendly friends who would be willing to babysit for an afternoon? Is there a dog park you haven’t tried, maybe at a beach within driving distance, or one that offers swimming or an agility course?
Finally, think of those things your dog reliably loves in life. Gather her favorite treats, toys, good juicy bones for chewing, and a comfy but portable bed or blanket.
