Symptom: Noisy Breathing – When Should I Contact a Vet?
What Does Noisy Breathing Look Like in Dogs and Cats?
Noisy breathing is often a sign that air is not moving normally through your pet's airways. Any sudden, severe or persistent noisy breathing should be assessed promptly by a vet, especially if your pet is struggling to breathe.
Common signs include:
Snoring, wheezing, rasping or unusually loud breathing
Laboured breathing or breathing with increased effort
Open-mouth breathing (especially in cats)
Stretching the head and neck forwards to breathe
Coughing, gagging or retching
Blue, grey or pale gums

Noisy Breathing in Pets: Frequently Asked Questions
What are the common reasons for noisy breathing
- Breed-related airway problems: flat-faced (brachycephalic) breeds, such as Pugs, Bulldogs and Persian cats, are prone to breathing difficulties because of their shortened airways. Further reading: BOAS condition
- Laryngeal paralysis or a collapsing trachea: these conditions narrow the airway and can cause noisy breathing, particularly during exercise or excitement.
- Respiratory infections or inflammation: swelling or inflammation affecting the upper airways can make breathing noisy.
- Airway obstruction: foreign bodies, tumours or other obstructions affecting the nose or throat can partially block the airway.
- Allergic reactions: swelling of the airways caused by an allergic reaction can make breathing noisy and may require emergency treatment. Further reading: Spring & Summer Dog Allergies
DO’s – What can I do at home if my pet’s breathing is noisy
