Quick Answer: Yes — puppies can and should wear a no-pull harness from the moment leash training begins. Starting with a front-clip harness teaches puppies that pulling does not work before the habit forms. It is far easier to prevent pulling in a puppy than to retrain it in an adult dog.
When to Start
Start harness training as soon as your puppy is vaccinated and cleared for outdoor walks — typically 10 to 16 weeks. The earlier you establish loose-leash walking, the less work you do later.
What Size for a Puppy
Most puppies start in XS (chest 12–16 inches, up to 15 lbs) or S (chest 16–20 inches, up to 30 lbs). Puppies grow fast — check the fit every 4 to 6 weeks and adjust or size up as needed.
