Tomlinson en Ladlow (2026)

Study shows that many brachycephalic dogs are healthy and do not exhibit BOAS. Key insight: physical characteristics explain only 20% of BOAS.

Gill

An analysis of earlier studies suggests that the relationship between muzzle length and breathing problems in dogs may be more complex than often assumed.

Packer

A study published in PLOS ONE shows that dogs with extremely short snouts have a significantly higher risk of severe breathing problems such as BOAS respiratory syndrome.

Lui

A study in PLOS ONE shows that the shorter and flatter a dog’s muzzle is, the higher the risk of severe breathing problems such as BOAS respiratory airway syndrome.

Ekenstedt
