Westie Collars: Sizing, Safety & Collar vs Harness


ðŸĶī

Collar, harness, or both? Here's how to choose, size and use a Westie collar safely — and when a harness is the better call.

The short answer

  • A collar is great for ID tags, but a harness is safer for walking a pulling terrier.
  • Measure the neck and follow the two-finger rule for fit.
  • Most Westies take a small / 10–14 inch collar.
  • Avoid leaving heavy or tight collars on a Westie's sensitive neck and coat.

Collar vs harness for Westies

👍 Collar

  • Holds ID tags neatly
  • Quick on and off
  • Fine for calm, trained walkers

👎

  • Pressure on the windpipe if they pull
  • Easier to back out of
  • Can rub the neck coat

For everyday walking, a harness protects the Westie's windpipe and gives better control. Keep a lightweight collar for ID, and clip the lead to a harness.

Sizing a Westie collar

Measurement Typical Westie
Neck girth 10–14 in (25–36 cm)
Collar size Small
Fit Two fingers should slide under it — snug, not tight
Width Narrow-to-medium; avoid heavy, bulky collars
ðŸū From one Westie owner to another —check collar fit regularly — between grooms the coat thickness changes, and a collar that fit at the groomer can get snug a few weeks later.
