It was 2 a.m. on a Tuesday when the frantic call came in. A 7-year-old Beagle named Charlie had started making a noise his owner, Karen, could only describe as “a goose stuck in my dog’s throat.” She was convinced he was choking. By the time they reached the clinic, Charlie had stopped the noise entirely and was wagging his tail, perfectly happy to see us. What Karen had witnessed was a classic reverse sneeze — one of the strangest, most alarming, and frankly most harmless sounds a dog can make. I’ve seen this scenario play out dozens of times in my exam room, and I never blame the owner for panicking. Some of these respiratory spasms sound absolutely terrifying. But here’s the thing: the specific noise your pet makes tells me an enormous amount about what’s going on, and learning to decode it can save you a midnight ER visit — or, more importantly, help you know when that midnight ER visit is truly warranted.
The Famous Reverse Sneeze (And Why It Sounds So Awful)
Let’s start with the big one, because this is the spasm that sends more dog owners to the vet — or the emergency clinic — than any other. A reverse sneeze is exactly what it sounds like: instead of forcing air out in a quick burst like a normal sneeze, the dog rapidly pulls air in through the nose. The result is a spasm of the soft palate and diaphragm that produces a loud, repeated snorting, honking, or gagging sound that can go on for 30 seconds or more.
I’ll never forget an English Bulldog named Margaret who came in last spring. Her owner, David, had filmed the entire episode on his phone — which, by the way, is the single most helpful thing you can do for your vet when this happens. Margaret stood with her elbows spread wide, neck extended, eyes bulging, making a rhythmic “SNORK-SNORK-SNORK” that sounded like she couldn’t breathe. David was shaking when he showed me the video. But Margaret? She’d been doing this once or twice a week for two years. It was completely benign.
Reverse sneezing is triggered by irritation in the nasal passages or nasopharynx — the area where the back of the nose meets the back of the throat. Common triggers include dust, pollen, strong odors, excitement, rapid eating or drinking, and pulling on a collar. Brachycephalic (flat-faced) breeds like Bulldogs, Pugs, and French Bulldogs are especially prone to it because of their compressed airway anatomy.
How to tell it’s a reverse sneeze
- The dog stands still, often with neck extended forward and downward
- The sound is rhythmic and repetitive — a consistent honk, snort, or gag
- It lasts between a few seconds and about a minute
- The dog returns to normal immediately afterward — no lingering distress
Gently massaging your dog’s throat or briefly covering their nostrils (which makes them swallow and can reset the spasm) often brings a reverse sneeze to a stop. But don’t try the nostril-covering trick if your dog is truly distressed or if you’re not certain that’s what’s happening.
Not Every Honk Is Harmless: When the Sound Changes
Here’s where I need to draw a firm line. The reverse sneeze is common and usually no big deal. But a new, persistent, or changing cough in a dog — especially a senior — is something I want to see and hear for myself. The auditory profile of a cough is one of our most valuable diagnostic tools. I tell my clients that to a veterinarian, a cough is practically a fingerprint.
A honking cough that sounds like a goose — particularly if it developed suddenly within a 24-hour period — is a classic presentation of infectious tracheobronchitis, commonly called kennel cough. I saw a 3-year-old Golden Retriever named Cooper just last month whose owner described the sound as “a seal barking in our living room.” It had started the day before. Cooper had been at daycare five days earlier. Classic timeline, classic sound. Kennel cough is usually self-limiting, but it can progress to pneumonia in some cases, so I always want to evaluate these dogs rather than having owners guess.
A soft, moist cough that’s worse at night or when the dog is lying down can point toward heart disease — specifically, an enlarged heart pressing on the main airway or fluid beginning to accumulate in the lungs. This is particularly common in senior small-breed dogs. A dry, hacking cough that worsens with excitement or pressure on the trachea (like from a collar) may indicate tracheal collapse, a condition I see frequently in toy breeds like Yorkies and Chihuahuas.
The gag that isn’t a cough
Gagging is physically caused by inflammation around the larynx, or voice box. Dogs gag for many reasons — infectious irritation, foreign material stuck in the throat, laryngeal paralysis, or even acid reflux. Because the list of possible triggers is long, there’s no substitute for a hands-on exam. I’ve had owners come in certain their dog has kennel cough, only for me to find a blade of grass lodged near the tonsils. I’ve also had owners dismiss a mild gag for weeks, only for us to discover laryngeal paralysis that was quietly narrowing the airway.
The Cat Conundrum: Hacking Isn’t Always a Hairball
If dogs are confusing, cats are downright misleading. I say this with love — I have two cats of my own, and one of them, a 12-year-old tabby named Olive, scared me half to death last winter with a hacking episode I initially dismissed as a hairball. It wasn’t. It was feline asthma.
Cat owners frequently interpret any hacking or gagging sound as an attempt to vomit a hairball. Sometimes they’re right. But cats with asthma produce a very specific kind of cough — it often looks like they’re crouched low to the ground, neck extended, making a dry, rhythmic hacking sound with little or nothing produced. If you’re seeing this more than occasionally, or if your cat seems to be breathing with slightly more effort afterward, we need to talk.
The danger with cats is that they hide respiratory compromise remarkably well. A dog in mild distress will often pace, pant, or act restless. A cat in the same situation may simply sit quietly in a hunched position and breathe a little faster. By the time a cat is openly struggling, the situation is often advanced. Watch for these accompanying signs:
- Increased respiratory rate at rest — more than 30 breaths per minute is worth investigating
- Open-mouth breathing in a cat (this is always an emergency)
- Lethargy or hiding more than usual
- Blue-tinged or pale gums
- Loss of appetite accompanying the coughing episodes
I’ve changed my mind about feline coughing over the years. Early in my career, I was more likely to take a watchful waiting approach with a hacking cat. After seeing how quickly some of these cases progressed — and after my own scare with Olive — I now recommend that any cat with a new or persistent cough be examined. The risk of missing feline asthma, heartworm-associated respiratory disease, or even early heart disease is simply too high to guess at home.
The Age Factor: Why Seniors Get New Tricks (And Not the Fun Kind)
Senior dogs and cats are particularly prone to developing new respiratory habits. As pets age, their immune systems weaken, making them more susceptible to infections. They’re also more likely to develop age-related conditions like heart disease, chronic bronchitis, and laryngeal paralysis — all of which can announce themselves as a “new cough.”
I managed a 13-year-old Miniature Poodle named Sophie who developed a soft, intermittent cough over the course of about three weeks. Her owner, an attentive woman named Patricia, almost didn’t bring her in because Sophie seemed fine otherwise — eating well, still walking enthusiastically. On exam, I heard a subtle heart murmur that hadn’t been present at Sophie’s visit six months earlier. Chest radiographs confirmed early-stage myxomatous mitral valve disease with mild left atrial enlargement. We started Sophie on medication before she ever developed heart failure symptoms, and that cough — which was caused by the enlarged heart pressing on her left mainstem bronchus — resolved completely.
The point isn’t that every senior cough means heart disease. The point is that the earlier we investigate, the more options we have. Conditions that are manageable when caught early can become crises when ignored.
Your Phone Is My Best Diagnostic Tool
One of the best developments in recent years — and something the veterinary literature has increasingly acknowledged — is the role of detailed owner histories combined with modern technology. A [1] emphasized what every clinician already knows: a thorough history from the owner is often more diagnostic than any single test.
Telehealth has expanded what’s possible here. More practices now offer virtual consultations where you can share audio or video clips of your pet’s episodes. When you film these moments, try to capture the whole body, not just the face. I want to see your pet’s posture, their breathing effort, whether their elbows are splayed, and what happens immediately after the episode ends. Context matters enormously.
Resources like [2] and expert platforms like [3] can be helpful starting points for understanding what might be going on, but they’re tools to inform your conversation with your own veterinarian — not replacements for one.
Red Flags: When to Stop Reading and Start Driving
Let me be direct about the situations where you don’t schedule an appointment — you go now:
- Blue, purple, or pale gums or tongue — this indicates oxygen deprivation and is an absolute emergency
- Labored breathing — visible effort with each breath, the chest wall sucking in, or the abdomen heaving dramatically
- Restlessness and inability to settle — a pet who keeps standing, pacing, lying down, and getting back up may be struggling to find a position where they can breathe comfortably
- Open-mouth breathing in a cat (cats are obligate nose-breathers under normal circumstances)
- Sudden onset combined with weakness or collapse
If none of these are present but the cough or spasm is new, persistent, or changing in character, call your vet and describe what you’re hearing. Most clinics would much rather have that conversation than see you three days later when things have progressed.
I want to leave you with this thought: you know your pet better than anyone. You’re the one who lives with them, hears them, and notices when something has shifted. That observational skill is invaluable, and I rely on it every single day in my practice. The goal isn’t to make you panic at every odd noise — it’s to help you recognize which noises are part of your pet’s normal repertoire and which ones are telling you something has changed. Respiratory conditions respond beautifully to early intervention, and catching a developing problem before it becomes a crisis is one of the kindest things you can do for the companion animal who trusts you with every breath.
