Picture this: your dog is sneezing more than usual, has a runny nose, and just wants to curl up on the sofa instead of racing to the door for a walk. Sound familiar? Your first instinct might be to wonder — is my dog coming down with a cold?
It’s a totally reasonable question, and you’re not alone in asking it. The short answer is yes, dogs can get something very similar to a cold. But here’s where it gets interesting — it’s not quite the same as what you or I catch every winter. Let’s break it all down so you know exactly what to look for, what to do, and when to call the vet.
Do Dogs Actually Get Colds?
Yes, but not in the exact same way humans do.
When we get a cold, it’s usually caused by the rhinovirus. Dogs don’t catch that specific virus — but they can develop upper respiratory infections caused by a range of bacteria and viruses that produce very similar symptoms.
Think of a “dog cold” as an umbrella term for any mild respiratory illness that causes sneezing, nasal discharge, coughing, and general tiredness. The experience looks similar; the cause is just different.
So if your dog is sniffly and sluggish in the middle of a British winter or during Canada’s freezing months, it’s not your imagination — they really can feel under the weather.
What Actually Causes Cold-Like Symptoms in Dogs?
Several different bugs can be behind your dog’s sneezing fit. The most common culprits include:
- Bordetella bronchiseptica — the main bacteria responsible for kennel cough
- Canine parainfluenza virus — very contagious, spreads fast in dogs that socialise
- Canine adenovirus — can affect the respiratory system
- Canine respiratory coronavirus — not the same as COVID-19, entirely different virus
- Mycoplasma — a lesser-known but common trigger of respiratory symptoms
These bugs spread easily between dogs, especially in places like dog parks, boarding kennels, groomers, and anywhere dogs share water bowls or sniff each other closely.
Cold and wet weather (hello, UK autumn!) doesn’t cause these infections directly, but it can stress your dog’s immune system and make them more vulnerable to picking one up.
Signs Your Dog Might Have a Cold
Here’s what to watch for. These symptoms usually appear within a few days of exposure to an infected dog:
- Sneezing — frequent or in bursts
- Runny nose — clear discharge is usually fine; yellow or green means bacteria may be involved
- Watery eyes
- Coughing — can be dry and honking (common with kennel cough) or wet
- Low energy — your usually bouncy dog just wants to nap
- Reduced appetite — not eating as much as normal
- Slightly laboured breathing in more serious cases
Most of the time, mild cold symptoms in dogs resolve on their own within 7–10 days, just like a human cold. But there are situations where you’ll want professional help — we’ll get to those shortly.
Kennel Cough vs. a Regular Dog Cold — What’s the Difference?
This is something a lot of dog owners get confused about, and it’s worth clearing up.
Kennel cough (officially called infectious tracheobronchitis) is a type of respiratory infection, but it tends to be more pronounced. The signature symptom is a harsh, honking cough — almost like your dog is trying to clear something from their throat. It spreads extremely quickly between dogs.
A general cold might just present as mild sneezing, a runny nose, and tiredness without the dramatic cough.
Both conditions are manageable, but kennel cough sometimes needs veterinary treatment, especially in puppies, elderly dogs, or those with other health conditions.
Can Dogs Catch a Cold From Humans?
This is one of the most common questions — and the good news is: no, your dog cannot catch your cold.
The viruses that make humans sick are species-specific. The rhinovirus that gives you a blocked nose in November won’t infect your dog, and your dog’s respiratory bugs won’t infect you either.
That said, if you’re ill yourself, it’s still good practice to wash your hands before handling your dog’s food or water bowls. Basic hygiene is always a good idea, even if cross-infection isn’t a real risk here.
Can Dogs Get the Flu?
Yes — and this one is worth knowing about separately.
Canine influenza (dog flu) is caused by influenza viruses specifically adapted to dogs: H3N8 and H3N2. Dog flu symptoms tend to be more severe than a regular cold and can include:
- High fever
- Persistent cough
- Thick nasal discharge
- Lethargy lasting more than a week
- Loss of appetite
Dog flu spreads rapidly in social settings. In Australia and Canada especially, outbreaks have been documented in kennels and dog shows. A vaccine is available in some countries — your vet can advise whether it’s recommended in your area.
What Should You Do If Your Dog Has a Cold?
Good news: most mild cases just need some TLC at home.
Home Care Tips That Actually Help
Keep them warm and comfortable. A cosy bed away from draughts makes a real difference. Dogs with mild respiratory infections feel the cold more, so a warm spot to rest is essential — especially if you’re in Canada or the UK during winter.
Make sure they’re drinking enough. Just like humans, hydration helps your dog’s body fight infection. If they’re going off their water bowl, try warming it slightly or adding a splash of low-salt chicken broth to encourage drinking.
Offer tempting food. A sick dog may turn their nose up at their regular kibble. Warming their food or offering something more aromatic (like a small amount of cooked chicken) can help.
Limit strenuous exercise. Short, gentle toilet walks are fine, but skip the long runs or rough play sessions until they’re back to normal. Rest is genuinely important here.
Keep them away from other dogs. If you suspect a respiratory infection, avoid dog parks and doggy daycare until your dog’s symptoms have cleared. This stops the infection spreading to other dogs.
Don’t give human cold medicines. This is really important. Medications like ibuprofen, paracetamol (acetaminophen), and many decongestants are toxic to dogs. Never medicate your dog with human products without veterinary guidance.
When You Should Call the Vet
Most dog colds clear up on their own — but there are clear warning signs that something more serious is going on:
- Symptoms lasting more than 10 days with no improvement
- Green or yellow nasal discharge (suggests bacterial infection)
- High fever (you can check by feel — a noticeably hot, dry nose and ears, or use a pet thermometer)
- Laboured or wheezy breathing
- Complete loss of appetite for more than 24–48 hours
- Puppies, senior dogs, or those with existing health conditions — these dogs need veterinary attention sooner rather than later as they have less immune reserve
- Symptoms that are getting worse, not better
Trust your gut, too. You know your dog. If something feels off beyond just a sniffle, it’s always better to get them checked.
How to Help Prevent Respiratory Infections in Dogs
You can’t bubble-wrap your dog, but there are practical steps that genuinely reduce the risk:
- Keep vaccinations up to date. The Bordetella vaccine (kennel cough vaccine) is widely available in the UK, Australia, and Canada. Many boarding kennels require it. It won’t prevent every respiratory illness but significantly reduces risk and severity.
- Choose reputable boarding and grooming facilities. Ask about their hygiene practices and vaccination requirements. Good facilities will have clear policies.
- Avoid crowded dog areas during local outbreaks. If you hear through your local dog-walking community that there’s a kennel cough outbreak in the area, give the dog park a miss for a couple of weeks.
- Support their immune system year-round. A balanced diet, regular exercise, good dental care, and managing stress all contribute to a stronger immune system.
- Don’t share water bowls between dogs. Especially with unknown dogs at parks or trails.
FAQ: Your Dog Cold Questions Answered
1.Can puppies get colds?
Yes, and they’re actually more vulnerable than adult dogs. Puppies have immature immune systems, so what might be a mild cold in an adult dog can become more serious in a young puppy. If your puppy is showing cold-like symptoms, contact your vet sooner rather than later.
2.How long does a dog cold usually last?
In most healthy adult dogs, mild cold symptoms clear up within 7 to 10 days with rest and home care. If your dog isn’t improving by day 10, it’s time to see a vet.
3.Is kennel cough the same as a dog cold?
Kennel cough is one specific type of canine respiratory infection, with a very distinctive honking cough as its hallmark symptom. A “dog cold” is a broader term that covers various upper respiratory infections. Kennel cough is generally more contagious and sometimes more severe.
4.Can my dog still go for walks if they have a cold?
Short, gentle walks for toilet purposes are usually fine. Avoid strenuous exercise and definitely avoid places where they’ll be in contact with other dogs — you don’t want to spread the infection.
5.Should I isolate my dog from other pets in the house?
If you have multiple dogs, it’s a good idea to limit close contact while one is symptomatic. Dog respiratory infections can spread between dogs in the same household. Cats are generally not at risk from dog-specific respiratory bugs.
6.Can dogs get colds in summer?
Yes — while respiratory infections are more common in cold, wet months (the immune system is under more stress), dogs can pick up respiratory bugs any time of year, particularly after contact with infected animals.
7.My dog’s nose is running but they seem fine otherwise — should I worry?
A small amount of clear nasal discharge with no other symptoms is usually nothing to worry about. Keep an eye on it over 24–48 hours. If other symptoms develop or the discharge becomes thick or coloured, call your vet.
Final Thoughts
Dogs can absolutely get sick with cold-like respiratory infections — and it can be worrying to watch your usually energetic companion feeling flat and sniffly. The reassuring truth is that most cases are mild and manageable with rest, warmth, hydration, and a bit of extra attention.
The key things to remember: keep vaccinations current, know the warning signs that need veterinary attention, and never reach for human medicines for your dog. When in doubt, your vet is always the right call — a quick phone consultation can save a lot of anxiety.
Your dog relies on you to notice when something’s off. The fact that you’re looking this up says you’re already doing a great job.
