Scientists from the University of Cambridge have identified as many as twelve dog breeds at risk of serious breathing problems due to their skull structure. While the issue was previously associated mainly with pugs and bulldogs, new research indicates an equally high risk for Pekingese and Japanese Chin. Researchers warn that the specific structure of the nostrils and shortened snout drastically reduce the quality of life of these canines, leading to chronic diseases.
12 At-Risk Breeds Identified
Scientists from Cambridge have shown that Pekingese and Japanese Chin suffer from the same conditions as pugs.
Symptoms Mistaken for Breed Nature
Snoring and wheezing are not characteristic traits but symptoms of respiratory failure.
Critical Impact of Overweight
Research proves that excess body weight dramatically worsens the prognosis for dogs with brachycephalic syndrome.
Research conducted by a team of scientists from the University of Cambridge sheds new light on the scale of health problems in short-snouted dogs. According to the latest analyses, brachycephalic syndrome (BOAS) affects a much wider group of animals than previously thought. A total of twelve breeds have been identified as predisposed to severe respiratory failure. Particularly at risk are Pekingese and Japanese Chin, whose anatomical structure almost prevents proper ventilation. Main risk factors are narrow nostrils, a wide but short skull, and overweight, which additionally burdens the circulatory and respiratory systems. Symptoms such as snoring, wheezing, rapid overheating, and sleep disorders are often mistakenly considered by owners as "cute" breed traits, while in reality they are symptoms of animal suffering. The breeding of dogs towards extreme physical traits, known as qualzucht (pathological breeding), became the subject of ethical and legislative debate in many European countries as early as the 1990s. Specialists emphasize that limited physical activity and difficulties in regulating body temperature are just some of the consequences of violating natural anatomical proportions. 12 — dog breeds show serious predispositions to BOAS In addition to the mentioned breeds, researchers point to moderate risk for popular Shih Tzu, Boxers, and French Bulldogs. Experts appeal to future owners to choose puppies from breeders prioritizing health, not just extreme appearance. „"Narrow nostrils and a flattened face are a combination of traits that drastically limit an animal's ability to function normally in daily life."” — Cambridge Scientists This research is intended to serve as a foundation for new guidelines for kynological organizations, aimed at eliminating structural defects through selective breeding focused on elongating the snout. Key Risk Indicators for BOAS: Skull Shape: Proportional, elongated → Shortened, wide (brachycephalic); Nostril Patency: Wide, allowing free inhalation → Narrow slits restricting airflow; Impact of Body Weight: Normal weight - fewer symptoms → Overweight - critical exacerbation of failure
