The correct way to measure a dog for ear muffs is to measure the head circumference just in front of the ears and under the chin, then size up if the measurement falls between ranges to ensure secure noise reduction.
Getting hearing protection wrong means the muffs either slide off or pinch until your dog shakes them loose. Most owners measure too far back and end up with a size that misses the ear canal entirely. The fix takes thirty seconds with a flexible tape measure and one rule—measure at the widest point in front of the ears, not over them. Below is the exact method, the brand-specific size charts you’ll need, and how to get a dog to actually keep the gear on during a hunt or fireworks night.

What You Need To Measure
A flexible cloth or plastic tape measure works best. If you don’t have one, a piece of string and a ruler will do—just mark the string where it meets and lay it flat against the ruler afterward. Avoid metal measuring tapes; they won’t curve cleanly around the jawline.
Where To Place The Tape
The tape must sit just in front of the ears, covering the base of the ear canal, then run under the chin along the jawline. This is the dog’s head at its widest point, and it matches how every major brand—Rex Specs, Soothe and Settle, Mutt Muffs—designs their sizing charts.
Do not measure over the top of the ears or behind the skull. That path gives a larger number that corresponds to a loose, ineffective fit. A tape placed too far back will recommend a size too big to seal properly against the ear canal, and noise reduction drops to near zero.
Read The Number And Size Up
Write down the circumference in inches. If the number falls exactly on a size boundary or between two sizes, choose the larger one every time. A slightly roomy fit keeps the padding from compressing the dog’s ears, which is the fastest way to make a dog reject the gear. A tight fit also hurts noise reduction—the material cannot expand properly to create the acoustic seal.
Brand-Specific Size Charts
Every manufacturer uses different ranges. The table below covers the three most common US models so you can match your measurement directly.
| Model | Size / Head Circumference | Notes |
|---|---|---|
| Rex Specs Ear Pro | Size 2: 13″–15″ Size 3: 15″–17.5″ Size 4: 17.5″–21″ |
Non-adjustable hoodie design; measure exactly per the method above. |
| Hush Muffs (Soothe and Settle) | Pick one size larger than your measurement | Manufacturer’s own rule: measure circumference just in front of the ears, then size up. |
| Mutt Muffs | Small: 12″–14″ Medium: 14″–17″ Large: 17″–20″ |
Stretchable design fits a broader range; often recommended for small to medium breeds. |
Common Mistakes That Ruin The Fit
Measuring over the ears. This is the single most frequent error. The tape must sit in front of the ears, not over them. A measurement taken over the ears can be two to three inches larger than the correct number, pushing you into a size that slides around the moment the dog moves.
Sizing down for a tighter feel. A smaller size feels snugger in the hands but presses the foam against the ear canal opening. Dogs respond by shaking their heads or pawing at the muffs until they come off. Noise protection is also compromised because the compressed foam cannot attenuate sound properly.
Introducing ear muffs for the first time during a noise event. If the first time your dog sees the muffs is when the fireworks start, they will associate the gear with fear and reject it. Baseline conditioning should start four to six weeks ahead of the planned use.
Soothe and Settle’s official sizing guidance reinforces the same principle: measure just in front of the ears and then choose a size larger than your measurement for a comfortable acoustic seal.
Check The Fit After Putting Them On
The muffs should stay put when the dog shakes its head or turns sharply. If they shift, the size is wrong or the adjustment straps need tightening. If they press hard enough to leave visible indentations after five minutes, size up. The seal around the ear canal should feel snug but not painful—similar to how well-fitting noise-canceling headphones feel on a human.
| Fit Check | What It Means | Action |
|---|---|---|
| Muffs shift easily when the dog moves | Too large | Go down one size or tighten straps if available |
| Deep indentations after removal | Too tight | Size up immediately; compression hurts the acoustic seal |
| Dog tolerates them for 5+ minutes without pawing | Good fit | Proceed to duration training |
| Muffs pop off during a shake | Wrong placement or too large | Remount and verify strap position; if still loose, size down |
Conditioning Your Dog To Accept Ear Muffs
Even a perfect fit fails if the dog will not keep them on. Rex Specs and the AKC recommend a gradual four-phase process starting four to six weeks before the expected noise event.
- Sniff. Place the ear muffs on the floor. Every time your dog sniffs or touches them, mark and reward with a high-value treat.
- Touch. Gently touch the muffs to one ear, then treat. Do this until the dog does not flinch or pull away.
- Hold. Open the muffs, hold them gently on the dog’s head for two seconds, treat, and remove. Increase the hold time by a few seconds each session.
- Duration. Put the muffs on fully and distract your dog with a favorite activity—fetch, a chew toy, or a training session. Work up to 15–20 minutes of wear time before the real noise event.
Patience during this phase determines whether the gear actually works when it matters. A dog that associates the muffs with treats and calm time will accept them during a thunderstorm or a day at the range.
Safety Caveats
Your dog should still be able to hear your voice and environmental cues for safety. Choose muffs made from non-breakable materials like ABS plastic or high-density foam to prevent injury if the dog shakes its head vigorously. Breeds with extremely wide jaws or low-set ears may require custom sizing from a manufacturer regardless of measurement—check the brand’s compatibility notes before ordering.
FAQs
What if I don’t have a flexible tape measure?
A piece of string works the same way. Wrap it around the head just in front of the ears and under the chin, mark where the ends meet, then lay that length flat against a ruler. Add a quarter-inch to account for the string’s slack, then compare to the size chart.
Can I use ear plugs designed for humans on my dog?
Human ear plugs are shaped for a different ear canal anatomy and will not stay in place on a dog. They also present a choking or swallowing hazard. Stick to veterinary-grade earmuffs designed specifically for canine head and ear structure.
Will ear muffs help with my dog’s noise anxiety?
Yes, but only if the dog is conditioned to wear them beforehand. Ear muffs reduce the intensity of startling sounds like thunder or fireworks, which can lower anxiety. The noise reduction is partial—your dog will still hear some sound—so pair the muffs with behavioral training for the best results.
How do I clean ear muffs after use?
Wipe the outer shell with a damp cloth and mild soap. Remove the foam pads if the brand allows it and hand wash in cool water. Let everything air dry completely before storing to prevent mildew inside the padding. Never submerge the electronic or non-removable parts.
Can puppies wear ear muffs?
Yes, but measure again every few weeks until the dog is fully grown. Puppies outgrow their head circumference quickly, and a set that fits at twelve weeks may be tight by six months. Check the fit before each use and move up a size as needed.
