Kennel cough symptoms in dogs usually start as a very noticeable cough and then may progress to other cold‑like signs.

Quick Scoop

What is kennel cough?

Kennel cough (also called canine infectious respiratory disease complex) is a contagious infection of the upper airways, a bit like a bad chest cold in humans. Dogs often catch it where many dogs mix, like kennels, daycare, or dog parks.

Classic kennel cough symptoms

Most dogs show one or more of these signs:

  • Persistent, harsh, “honking” or hacking cough, often worse with excitement or pulling on the collar.
  • Cough that may sound like gagging, retching, or like something is stuck in the throat.
  • Sneezing and runny nose.
  • Watery or mucous eye discharge.
  • Mild tiredness or reduced energy.
  • Mild fever and slightly decreased appetite in some dogs.

Owners often describe it as their dog “coughing like a goose honk” or “trying to vomit but nothing comes up.”

More serious warning signs

While many cases are mild, some dogs (puppies, seniors, or those with other health issues) can get sicker and may need urgent vet care.

Watch for:

  • Trouble breathing, rapid or labored breaths.
  • High fever, marked lethargy (very weak, not wanting to move).
  • Not eating or drinking normally.
  • Cough lasting more than 7–10 days or clearly worsening.

These can signal complications like bronchitis or pneumonia and should be checked by a vet quickly.

How it feels for your dog (story style)

Imagine your dog picked up a “doggy cold” at daycare: two to three days later they start making loud honking coughs every time they get excited or tug the leash, but they still beg for walks and eat fairly normally. That picture fits typical, uncomplicated kennel cough. If, instead, they start to cough and then lie around, ignore food, and breathe harder even at rest, the infection may be moving deeper into the lungs and needs veterinary attention.

Latest angle and what to do now

Recent pet‑health articles still describe kennel cough the same way: a common, usually mild but highly contagious respiratory infection that spreads quickly wherever dogs gather. Annual vaccination and good hygiene in kennels and dog parks are emphasized as key prevention steps.

If your dog has a new, harsh cough, the safest steps are:

  1. Keep them away from other dogs until a vet clears them.
  2. Call your vet, describe the cough sound and other symptoms, and follow their advice on whether they need an in‑person exam.
  3. Monitor closely for any breathing difficulty, poor appetite, or worsening lethargy and seek urgent care if these appear.
