The Pug is one of the most popular and most controversial breeds in the UK. Their charming, clown-like personality, affectionate nature, and undeniable appeal as a companion dog are genuine — Pugs are funny, loving, and deeply bonded to their owners. However, the Kennel Club classifies the Pug as a Category Three breed (the highest health concern tier), and a 2022 Royal Veterinary College study found that Pugs are nearly twice as likely to experience health disorders compared to non-Pugs. This guide presents the full reality.

Health — The Four Critical Conditions

1. BOAS — Brachycephalic Obstructive Airway Syndrome

Approximately 60% of Pugs are affected by BOAS — a condition caused by their extremely shortened skull compressing the airway structures:

  • Anatomical problems: Stenotic (narrowed) nostrils, elongated soft palate, hypoplastic (narrow) trachea, everted laryngeal saccules
  • Symptoms: Constant snoring, snorting, gagging; exercise intolerance; overheating in warm weather; sleep-disordered breathing (some Pugs sleep sitting up because lying down occlude their airways further)
  • Critical distinction: Noisy breathing in a Pug is not normal — it is a symptom of airway obstruction. Owners who normalise snoring are normalising suffering
  • Treatment: Surgical correction (widening nostrils, shortening soft palate) can significantly improve quality of life. Weight management is essential — even mild overweight in a Pug dramatically worsens BOAS

2. PDE — Pug Dog Encephalitis

PDE (Necrotizing Meningoencephalitis) is a fatal inflammatory brain disease virtually unique to Pugs:

  • Typically presents between 6 months and 3 years of age
  • Symptoms: seizures, disorientation, circling, blindness, personality change, progressive neurological decline
  • Most affected dogs die or are euthanised within 3–6 months of symptom onset
  • Genetic test available — the NME gene test identifies susceptibility. Responsible breeders test all breeding dogs. This does not guarantee disease-free puppies but significantly reduces risk

3. Syringomyelia (SM)

Syringomyelia occurs when fluid-filled cavities develop within the spinal cord, often linked to Chiari-like malformation (the skull is too small for the brain). Pugs are among the most commonly affected breeds:

  • Symptoms: phantom scratching (scratching at the neck/shoulder without making contact), sensitivity to touch around the head and neck, pain, yelping when touched
  • Diagnosis requires MRI — many cases go undiagnosed because owners attribute the scratching to skin problems
  • Treatment: pain management (gabapentin, NSAIDs); surgery in severe cases (foramen magnum decompression)

4. Eye Emergencies

The Pug’s extremely prominent, bulging eyes are highly vulnerable. Approximately 19% of UK Pug vet visits involve eye problems:

  • Proptosis — the eyeball can be displaced from the socket by surprisingly minor trauma. This is an immediate veterinary emergency
  • Corneal ulcers — exposed corneas dry out and are easily scratched
  • Pigmentary keratitis — brown pigmentation spreading across the cornea, progressively impairing vision

FAQs

Should I buy a Pug?

This is the most ethically complex question in UK dog ownership. If you are committed to a Pug, seek breeders who breed for longer muzzles (sometimes called “retro Pugs” or “sport Pugs”), conduct BOAS grading on breeding adults, test for PDE/NME, and can demonstrate open nostrils and quiet breathing in their dogs. Consider adopting an adult Pug through PDWRA or other rescues — you can assess their breathing and existing health status before committing. Budget generously for veterinary care throughout the dog’s life.
