Collars and harnesses both have their place. A collar is handy for ID tags, while a harness spreads the pull of the leash across your dog's chest and shoulders instead of the neck. Many owners use both.
When a harness can help
- Your dog pulls on the leash or lunges at distractions
- You want a handle to steady your dog at crossings or getting in and out of the car
- Your dog seems uncomfortable with pressure on the neck
- You're taking longer walks, hikes or trips
If your dog has a medical condition affecting the neck, back or breathing, ask your veterinarian which option is best.
How to measure your dog
- Chest (girth): wrap a soft tape measure around the widest part of the chest, just behind the front legs.
- Neck: measure around the base of the neck, where a collar would sit.
- Compare: check both measurements against the size chart. If your dog is between sizes, choose the size whose adjustment range covers both measurements comfortably.
The two-finger fit check
Once the harness is on and adjusted, you should be able to slide two fingers flat under every strap. Too loose and your dog may back out of it; too tight and it can rub. Check that the straps don't sit in the armpits, and re-check the fit after the first few walks as the straps settle.
Getting your dog used to a new harness
- Let your dog sniff the harness and reward them.
- Put it on for a few minutes indoors, with treats and praise.
- Take short walks first, then build up to longer outings.
Care tips
Check buckles and stitching regularly, and wash the harness when it gets dirty, following the care instructions. Replace any harness with damaged hardware.
