Living in Union City, we love taking our dogs to local parks and walking trails. However, social interaction comes with risks. If your dog has suddenly started making strange noises, hacking, or has a runny nose, you might be worried.

Is it just a "doggy cold"? Or could it be Kennel Cough or Canine Influenza?

While dogs can suffer from minor respiratory bugs, distinguishing them from serious conditions requires a professional eye. If your pet seems sick, call Union City Veterinary Medical Center at (510) 441-8500 to book an exam.

Can Dogs Catch Colds From People?

The short answer is no.

If you are sick with the flu or a cold, your dog is safe from you. The viruses that affect humans generally do not cross over to canines.

However, dogs are highly susceptible to their own set of contagious respiratory viruses. These pathogens spread easily through direct contact (sniffing noses), shared water bowls, or even just being in the same room as a coughing dog.

🚨 EMERGENCY WARNING SIGNS

Some symptoms indicate a life-threatening situation. Seek immediate veterinary care if your dog:

  • Is struggling to breathe (gasping, open-mouth breathing when calm)
  • Has pale or blue-tinted gums
  • Collapses or cannot stand up
  • Coughs up blood
  • Refuses to drink water or eat for more than 24 hours

Note: Our clinic is open Tuesday through Saturday. If you have an emergency on Sunday or Monday, please proceed to the nearest emergency animal hospital.

7 Key Symptoms of Respiratory Infection

Respiratory issues in dogs often look like a bad flu. Here is what our veterinarians look for:

1. The "Honking" Cough

A dry, harsh cough that sounds like a goose honk is the hallmark symptom of Bordetella (Kennel Cough). It is often triggered by excitement or pulling on the leash.

2. Nasal Discharge

A little clear drip might be normal, but thick, yellow, or green mucus is a sign of infection.

3. Reverse Sneezing vs. Regular Sneezing

Frequent sneezing can irritate the nasal passages. "Reverse sneezing" (a rapid inhaling sound) can be scary but is often harmless, though it can accompany infections.

4. Lethargy

Is your usually playful pup sleeping more than usual? Fighting a virus takes energy, leaving them tired and withdrawn.

5. Fever

A dog's normal temperature is higher than ours (up to 102.5°F). If their ears or paws feel excessively hot and they are acting dull, they may have a fever.

6. Eye Irritation

Red, watery, or gunky eyes often go hand-in-hand with respiratory viruses.

7. Loss of Appetite

A stuffed-up nose means they can't smell their food, which often leads to them refusing to eat.

🔍 Concerned about these signs? Don't wait. Call (510) 441-8500 to schedule an appointment at our Union City clinic.

Special Care for Puppies and Seniors

Age matters. A robust adult dog might shake off a mild virus with a few days of rest, but puppies and senior dogs are at high risk.

Puppies have developing immune systems, and seniors may have underlying health issues. For these pets, a simple cough can rapidly escalate into pneumonia, which requires hospitalization. We recommend seeing a vet immediately for any respiratory symptoms in young or older pets.

Beyond the "Cold": Other Culprits

Why do we advise against diagnosing your dog at home? Because coughing doesn't always mean a cold. It could be:

Allergies

Seasonal pollen can cause itching and sneezing.

Heart Disease

A failing heart can cause fluid buildup in the lungs, leading to a "soft" cough, especially at night.

Fungal Infections

Inhaling certain spores can cause severe respiratory distress.

Collapsing Trachea

Common in small breeds (like Yorkies), causing a chronic honking cough.

Only a veterinarian can tell the difference.

What You Can Do at Home

While you wait for your appointment at Union City Veterinary Medical Center, you can make your pet more comfortable:

  • No Human Medicine: Never give Tylenol, Ibuprofen, or cold medicine. These can be deadly.
  • Humidify: A humidifier in the room can help soothe dry airways.
  • Rest: Keep them quiet. No walks, no playdates, and definitely no dog parks until they are recovered to prevent spreading the virus.
  • Hydration: Add a little warm water to their kibble to encourage eating and drinking.

Prevention is Key

The best way to treat a respiratory infection is to prevent it.

1

Vaccination

Keep your dog up to date on Bordetella and Canine Influenza vaccines, especially if they go to groomers or boarding.

2

Avoidance

If you hear a dog coughing at the park, leave the area immediately.

3

Hygiene

Wash your hands after petting other dogs before touching your own.

Frequently Asked Questions

My dog is eating fine but coughing. Should I still come in?

Yes. Dogs are resilient and will often eat even when sick. However, a persistent cough is contagious and can worsen. It is best to get checked early.

How do I know if it's allergies?

Allergies usually come with itchy skin, paw licking, and clear discharge. Infections usually bring fever, lethargy, and thick/colored discharge. We can help distinguish between the two.

Is Kennel Cough treatable?

Yes. While it is viral (like a human cold), we often prescribe medications to prevent secondary bacterial infections and cough suppressants to help your dog sleep and heal.
