Hearing science
Dogs hear more than we do, and loud noise is the most common thing they fear. Here's what the research says, with a link to every source.
A dog's hearing reaches far higher than ours. Dogs pick up sound from roughly 67 Hz to 45 kHz, while people top out around 23 kHz (and start near 64 Hz). That extra range means high-pitched sounds we barely notice, or can't hear at all, still reach a dog's ears. LSU School of Veterinary Medicine
Researchers at the University of Helsinki looked at survey data on about 13,700 pet dogs. Noise sensitivity came out as the most common anxiety trait, seen in 32% of dogs, and around 26% were afraid of fireworks in particular. Salonen et al., Scientific Reports, 2020
Other studies put the share of noise-sensitive dogs anywhere between 20% and 50%. A 2005 RSPCA survey found that 49% of UK dogs showed some fear of fireworks, thunder or gunshots. Vet Times
Breed matters too. A Norwegian study of 5,257 dogs across 17 breeds found large differences in how sensitive each breed was to noise. AVSAB summary
Big, rare events get the attention, but researchers also report that ordinary household noises can trigger fear and anxiety in dogs. Think vacuums, blow-dryers, smoke alarms and kitchen clatter. Frontiers in Veterinary Science, 2021
The American Kennel Club points out that the same sharp hearing that helps dogs also makes them more vulnerable to intense noise, and that fireworks at close range may damage their hearing. The AKC adds that well-fitted, noise-reducing ear muffs can offer some protection, and work best alongside behavior training. AKC: Ear muffs for dogs
Working dogs ride in helicopters and work near gunfire, so the US Army supported research into hearing protection built for them. When it was tested during helicopter operations, researchers saw a significant reduction in short-term hearing loss. EurekAlert · U.S. Army
That research tested hearing protection made for military working dogs, not PAWSHHH.
Ear muffs can help muffle sounds for some dogs.
Add canine ear protection during storms and holidays.
Dog-specific ear protection is an option, though no single tool works for every dog.
Summarized in our words; follow each link for the full article. These vets are talking about dog hearing protection in general, not about PAWSHHH.
PAWSHHH is passive hearing protection for dogs, with a lab-rated SNR 29 dB* and a 3-point fit designed to help keep the cups in place. There are no batteries and nothing to charge.
It works best as one layer in a plan: a quiet space, gradual training so your dog is relaxed wearing it, and your vet's advice.
*Manufacturer lab rating. Real-world reduction varies with fit, head shape and coat.
