My Dog Is Coughing — What Does It Mean?
A dog cough can sound like anything from a gentle hack to a loud honking goose-like noise. Coughing is the body's way of clearing the airway, but chronic or severe coughing can point to serious conditions that need prompt attention.

home What To Do at Home

What does kennel cough sound like?
Kennel cough is typically a loud, honking cough — like a goose sound. Dogs often cough multiple times in a row and may gag afterward.
Can kennel cough kill a dog?
Most healthy dogs recover fully within 1–3 weeks. However, puppies, senior dogs, and immunocompromised dogs can develop pneumonia, which can be serious.
What is reverse sneezing in dogs?
Reverse sneezing is a rapid, forced inhalation of air through the nose, making a snorting or honking sound. It looks alarming but is usually harmless. It's caused by irritation in the throat or nasal passages.
Does my dog need antibiotics for kennel cough?
Mild cases often resolve without antibiotics. Your vet may prescribe them for severe cases or to prevent secondary bacterial infections.
