A collar, harness and leash do different jobs. The best choice depends on your dog's size, walking habits, comfort, and the instructions for the product.
Collars: Measure before you buy
Measure around the part of the neck where a collar sits, then compare that measurement with the manufacturer's specific size chart. Fit should be secure without digging in or slipping over the head. Check the adjustment and hardware regularly, especially for growing dogs.
Harnesses: Look at chest and shoulder fit
Many harnesses are sized by chest girth rather than weight alone. Check the manufacturer's sizing instructions, where the straps sit, and whether the design lets your dog move comfortably. A front attachment, rear attachment or handle may serve different walking needs; none guarantees that a dog will stop pulling without training.
Leashes: Consider control and comfort
Choose leash length and hardware suited to your surroundings and dog's strength. Inspect the clip, stitching and attachments routinely. Introduce unfamiliar gear in a quiet location before using it near traffic.
