Key Takeaways
Can dogs wear earplugs? Not in any way we would recommend. A dog’s ear canal drops straight down and then turns inwards towards the eardrum, so a plug either sits loose at the top, where one head shake throws it out, or gets pushed down towards the bend, where it can lodge and need a vet to retrieve it. The passive form that does work on a dog is an over-ear muff (ear muffs, called ear defenders in the UK) that covers the whole ear flap and seals against the head.
At BOLLSEN we are a family-owned hearing protection company, founded in 2016 and trusted by 1,000,000+ people, and dog hearing protection is part of what we make. Every autumn, a few days before the fireworks, owners ask “do they make earplugs for dogs?” Below we look at what people actually try and why each runs into a dog’s anatomy.
Can dogs wear earplugs?
Dogs cannot wear earplugs safely or reliably, because the canine ear canal is L-shaped, running down from the base of the ear flap (pinna) and then turning roughly 90 degrees inwards, so a plug has nothing straight to grip and no safe depth to sit at.
Human earplugs are made for a fairly straight human canal and a wearer who can feel when a plug goes in too far. A dog has neither. In-ear products sold as “dog ear plugs” meet the same geometry.
Why won’t an earplug stay in a dog’s ear?
An earplug won’t stay in a dog’s ear because the vertical canal gives a plug little to grip, and because head shaking is the dog’s built-in way of clearing anything from the canal, so the plug is working against a reflex the dog uses many times a day.
VCA Animal Hospitals refers to the canal’s vertical part and its horizontal part, which is why a plug has no straight path to sit in. Owners who have tried silicone swimmer’s plugs on their dogs report the same result. The dog paws at its ears, shakes hard, and the plugs go flying.
Floppy ears add a second problem. The ear flap folds over the opening, so you cannot see whether the plug is still in place or sliding further down.
What can go wrong if something gets stuck in a dog’s ear canal?
A plug pushed past the vertical canal can lodge near the bend as a foreign body, where it may irritate the lining, hold moisture against the skin and press towards the eardrum, and PetMD advises having a vet examine the ear before anyone tries to remove a lodged object.
Ear trouble is already common in dogs. A VetCompass study of 22,333 dogs under UK primary vet care found a one-year prevalence of otitis externa (inflammation of the outer ear canal) of 7.30%, and dogs with pendulous ears had 1.76 times the odds of dogs with erect ears. Repeated head shaking, scratching at one ear, a tilted head or any discharge after something has been in the ear are all reasons to speak to your vet the same day.
Can you put cotton wool in a dog’s ears for fireworks?
A large, loose piece of cotton wool in the opening of the ear is a common owner trick that some vets have suggested, but it muffles very little sound and is only safe if it is far too big to travel down the canal.
On one UK horse and dog forum, an owner’s advice was blunt: make sure the pieces are “not too small so you don’t have to go on a fishing expedition at the vets!” Another reminded everyone to pull it out before walkies. Good advice, because a dog that cannot hear you on a walk is harder to recall.
Owners who have tested cotton pads in their own ears describe them as very bad at blocking noise, and cotton that works its way in can irritate the canal. Ask your vet to show you how to place it, or skip it.
Can a dog wear human ear defenders?
A dog can’t wear human ear defenders properly, because they are built to clamp on the flat sides of a human skull with the ears level with the cups, while a dog’s ear flap sits higher and further back on a long, narrow head, so the cups gap, the seal breaks and the band slides off.
Clamping pressure is set for an adult human head, not a terrier or a spaniel. And a cup that does not seal around the ear flap lets sound straight in under the rim.
Parents weigh the same earmuffs vs earplugs question for their children, where ear size and seal decide it. Our guide comparing earmuffs vs earplugs for kids covers that human side.
So what does work for a dog’s ears?
What works is an over-ear muff made for dogs, with padded cups that cover the whole ear flap and an adjustable headband shaped for a dog’s head, so nothing enters the ear canal and the seal sits on the skin around the ear rather than inside it.
Dogs hear a far wider range than we do, roughly 67 Hz to 45 kHz against roughly 64 Hz to 23 kHz for humans, according to the hearing-range table published by the LSU School of Veterinary Medicine. Matija Medved, DVM, of the Dr.Vet clinic notes that dogs can experience discomfort or hearing damage from around 85–90 dB, while humans stay comfortable up to about 110–120 dB, and a hoover runs at about 90 dB. His reasoning on canine noise thresholds is set out in Dr.Vet’s expert review of Dog+ hearing protection.

Our Dog+ follows this over-ear design, with soft padded cups, an adjustable flexible headband, reflective stitching and four sizes that fit most breeds. Because the cups sit outside the canal, there is nothing for a head shake to throw out or push down.
Seal, headband adjustment, size range and a published SNR rating are what separate the best dog ear muffs from the rest, and our buyer guide to best dog ear muffs: what to look for lets you check any pair against that list before you buy. Our Dog+ earmuffs (SNR 27 dB, sizes XS to L, £69.95) are measured on that basis, and the dog ear muff sizing guide shows how to measure the ear base for a sealed fit.
| Option | Where it sits | Stays on when the dog shakes? | Main drawback | Noise reduction evidence |
|---|---|---|---|---|
| Human foam or silicone earplug | Inside the vertical ear canal | No, usually thrown out | Can lodge near the bend; a dropped plug can be swallowed | None measured on dogs |
| Cotton wool | Loose in the ear opening | Sometimes, if large | Can work inwards and irritate | Very little muffling |
| Human ear defenders | Over the head, cups misaligned | No, the band slides off | Clamp pressure set for a human head; seal gaps | Rating does not apply without a seal |
| Over-ear dog ear muffs (Dog+) | Over the ear flap, sealed on the head | Yes, when sized and adjusted | Needs gradual introduction and supervision | SNR 27 dB (H 29 / M 26 / L 19) |
Do over-ear muffs actually work on fireworks and thunder?
Over-ear muffs work best on the sharp, high-pitched part of fireworks, the crackle and whistle, and less on the low thump and the rumble of thunder, because Dog+ is rated at SNR 27 dB with H 29 / M 26 / L 19, which means low frequencies are reduced least.
The dog still hears that something is happening, only quieter, while a ~90 dB hoover gets the full M/H 26–29 dB. Treat the muffs as one physical layer in a plan that also includes a den, a steady routine and your vet’s advice.
The frequency data behind those figures, including why the low end gets through most, is in our breakdown of how much noise dog ear muffs reduce, measured across eight bands from 63 Hz to 8 kHz. If a particular night is coming up, our guide to dogs and fireworks covers preparing the house before the season starts.
Is an over-ear muff safer than an earplug?
An over-ear muff is the safer choice for a dog, because it sits outside the ear canal, can be checked at a glance and comes off in one movement, whereas a plug that slips inwards can become a problem only a vet can solve.
Introduce the muffs over several short sessions with treats before any noisy night, give a break every 1–2 hours, and never leave the dog alone in them. Owners who ask “are dog ear muffs safe” usually find the answer comes down to fit, supervision and those regular breaks.
Take them off before a walk, for the same recall reason as the cotton wool. Where a dog shows strong fear of noise, the RSPCA recommends seeking advice from your vet, and our guide on how to help a dog through thunderstorms explains when to bring your vet in.
So, can dogs wear earplugs? Not safely. The L-shaped canal and the head-shake reflex work against anything pushed into the ear, cotton wool barely muffles sound, and human ear defenders do not fit a dog’s head. An over-ear muff built for dogs avoids the canal entirely and is designed to reduce the noise reaching your dog’s ears.
Pick a pair with a published SNR and a proper size range, practise little and often, and keep your vet in the loop. The next noisy night will be easier to plan for both of you.
