Military and police dogs face helicopter cabins, loud kennel blocks and training ranges. Here is what units actually use, what a flight does to a dog’s hearing, why many forces keep ears bare on deployment and where a passive over-ear muff honestly fits.

A sock or fleece tube over a dog’s head keeps the ears flat but cannot seal, so it blocks little sound. What homemade covers are good for, the chewing and heat risks, and what to do if fireworks start tonight.

Three Nordic studies of more than 18,000 dogs found clear breed differences in firework fear, from the Norwegian Buhund and Lagotto Romagnolo at the top to the Labrador and Boxer near the bottom. Here is what each study found, what else shapes fear, and how breed affects ear shape and ear muff size.

Ear muffs, snoods, pressure wraps, training and vet-led options each work in a different way, and only one reduces the sound reaching your dog’s ears. Here is what each does, what it costs and which ones combine.

A dog’s ear canal drops down and then turns inwards, so earplugs either fly out at the first head shake or get pushed towards the bend. Why plugs, cotton wool and human ear defenders fall short, and what fits a dog instead.

A dog that sleeps through the doorbell or startles at a touch may be losing its hearing. Here are the six signs to watch for, a home test that avoids false results, the three main causes and when a BAER test or a vet visit is the next step.

Dog ear muff sizing comes down to one tape measurement over the ear base and under the chin. Here is how to take it, which Dog+ size it points to, and how to check the fit at home.

Most products sold as noise cancelling headphones for dogs are passive ear muffs. We explain why active noise cancelling misses a firework crack, what passive cups do instead and why fit matters more than the label.

Professional force dryers measure 94.8–108 dBA at one metre. What that means for a dog at the grooming table and for a groomer all day, when to fit ear muffs, and how a snood compares.

Sound training works best months before the first bang. This plan covers graded exposure paired with food, a week-by-week schedule, the thunder track, the failure modes and why ear muffs belong to the real night, not the practice.
