Coughing and Sneezing

For most pet coughing and sneezing – kennel cough, upper respiratory infections, allergies, mild asthma flares, post-nasal drip – urgent care is the right venue, not the ER. Go to a 24-hour emergency hospital only for signs of true respiratory distress.

Breathing problems are the one category where urgent care has the lowest threshold to refer to the ER, because low oxygen becomes life-threatening quickly. We can handle the vast majority of coughs and sneezes – kennel cough, URIs, allergies, mild asthma – in-clinic with antibiotics, cough suppressants, bronchodilators, and supportive care. But if a pet is in active respiratory distress, the ER has 24-hour oxygen support and overnight monitoring that we don’t.

Bring your pet to urgent care if:

• Persistent cough or sneeze lasting more than 24–48 hours
• Nasal or eye discharge, even if the pet seems otherwise okay
• Reverse sneezing or occasional gagging episodes
• Mild wheezing or noisy breathing that resolves with rest
• Cough triggered by excitement or pulling on the leash
• Recent boarding or daycare exposure with a new cough (likely kennel cough)
• It’s after-hours and your regular vet is closed or fully booked

Go straight to an ER instead if your pet has:

• Blue, gray, or pale gums (signs of low oxygen)
• Open-mouth breathing in cats (almost always a serious sign)
• Severe coughing with no breaks, especially standing with elbows out and neck extended
• Gasping, non-stop panting at rest, or visibly labored breathing
• Choking that doesn’t resolve, or coughing up blood
• Collapse, extreme weakness, or signs of shock

Bring your pet in if a cough or sneeze has lasted more than 48 hours, gets worse, comes with discharge or fever, or is interfering with sleep or eating.

Don’t wait if you notice:

• Cough lasting longer than 48 hours
• Cough getting worse over a day or two
• Nasal or eye discharge – especially yellow or green
• Wheezing or noisy breathing
• Sneezing fits, especially frequent reverse sneezing
• Cough paired with lethargy, fever, or loss of appetite
• Coughing fits severe enough to disturb sleep or eating
• A puppy or kitten with respiratory symptoms – they decline faster

Respiratory infections in pets can progress from mild to serious quickly, particularly in puppies, kittens, senior pets, and brachycephalic breeds (pugs, bulldogs, Persians). A cough that’s stable today can become pneumonia within a couple of days if left untreated. Treat respiratory symptoms with a lower wait-and-see threshold than you would for most other minor issues.

The most common causes are upper respiratory infections (kennel cough in dogs, URIs in cats), allergies, asthma, heart disease, foreign objects in the airway, and underlying conditions like collapsing trachea or heartworm disease.

Coughing and sneezing can look similar from the outside but come from very different sources – the throat, the airways, the lungs, the heart, or the nasal passages. Identifying which structure is involved matters, because the treatment for kennel cough is very different from the treatment for asthma or heart disease.

Common causes we see:

• Kennel cough – bacterial or viral, highly contagious, common after boarding or daycare
• Upper respiratory infections in cats – usually herpesvirus or calicivirus
• Allergies – pollen, dust, mold, or household irritants
• Asthma – especially in cats, often triggered by environmental factors
• Heart disease – a heart-related cough is more common in older dogs
• Heartworm disease – can present as a chronic cough
• Collapsing trachea – common in small breeds, causes a goose-honk cough
• Foreign objects – grass, seeds, or debris in the airway
• Pneumonia – bacterial, viral, or aspiration
• Tumors or growths – less common but possible, especially in older pets

Mild upper respiratory infections typically clear in 7–14 days with treatment. Coughs lasting more than 2 weeks or worsening at any point need a vet – they may signal a more serious condition.

Kennel cough often resolves in 1–3 weeks, even without antibiotics, though treatment shortens the course and helps prevent secondary infection. Cat URIs follow a similar timeline. Chronic conditions – asthma, heart disease, collapsing trachea, allergies – don’t resolve but can be well-managed with the right medication. A persistent cough or sneeze, especially in older pets, deserves a full evaluation because it’s often the first sign of something more significant like heart disease or a lung tumor.

We start with a thorough chest and airway exam, listen to the heart and lungs, and use X-rays, bloodwork, or specialized tests as needed – most respiratory cases are diagnosed in a single visit.

Diagnosing respiratory problems is about localizing the issue – is it in the throat, the airways, the lungs, or the heart? – and identifying the cause (infection, allergy, foreign body, structural, or systemic).

Depending on what we find, we may recommend:

• Auscultation – listening to the heart and lungs to identify abnormal sounds
• X-rays – chest imaging to assess the lungs, airways, and heart
• Bloodwork – checks for infection, inflammation, and organ function
• Heartworm test – important whenever a cough is unexplained
• Nasal or pharyngeal exam – for sneezing pets or those with discharge
• Tracheal swab – when the source of infection needs to be identified
• Referral for advanced imaging – for suspected tumors or complex disease

Before we run anything, we’ll show you the proposed plan and the cost. You decide what to approve.

Most pets go home the same evening with antibiotics (if bacterial), cough suppressants, anti-inflammatories, and a clear care plan – only severe respiratory distress, pneumonia requiring oxygen, or heart failure need an ER referral.

Common treatments include:

• Antibiotics – for confirmed or suspected bacterial respiratory infection
• Cough suppressants – to reduce coughing fits and allow rest
• Anti-inflammatories or steroids – for allergic or asthmatic causes
• Bronchodilators – to open constricted airways
• Antivirals – in select cases of viral URI in cats
• Fluid therapy – for dehydrated or feverish pets
• Nebulization – to help clear thick congestion
• Heart medications – when heart disease contributes to a cough
• Referral to a 24-hour hospital – for pneumonia needing oxygen, severe asthma, or heart failure

Keep your pet calm, in clean air, and well-hydrated – but don’t give human cold medications or wait if breathing becomes labored at rest.

Safe home steps before your visit:

• Keep your pet in a calm, low-activity environment
• Provide clean, dust-free air – avoid candles, smoke, aerosols, and harsh cleaners
• Run a humidifier or briefly take your pet into a steamy bathroom to ease congestion
• Ensure plenty of fresh water – hydration helps thin mucus
• Use a harness instead of a collar if your dog has a tracheal cough
• Note the cough’s pattern (when it happens, what triggers it) and any other symptoms
• Keep your pet isolated from other animals in case they carry a contagious disease

Don’t give human cough or cold medications. Most contain ingredients (acetaminophen, ibuprofen, decongestants) that are toxic to dogs and cats. And don’t ignore breathing that’s labored at rest, even if your pet was “fine yesterday” – respiratory problems can escalate from manageable to dangerous overnight, especially in cats, puppies, senior pets, and flat-faced breeds.

We see your pet the same evening, listen to the heart and lungs, run X-rays in-clinic, and start treatment that night – the right place for the right problem, with clinic, wait, and cost structured around your pet’s case.

What that looks like in practice:

• Walk in or “Save My Spot” online to join our waitlist
• Chest auscultation, X-rays, and bloodwork done in-clinic
• Treatment plan and pricing reviewed with you before anything starts
• Stay with your pet through exam and treatment if you want to
• Same-evening relief for most cases – go home with the medication and a clear plan
