About: Brachycephalic
Obstructive Airway Syndrome (BOAS)
The symptoms are:
- shortness of breath, snoring,
- wheezing,
- gagging, regurgitation,
- exercise/heat intolerance.
Anatomical abnormalities seen in many breeds are believed to be directly related to their skull conformation (shape). Reason is because there is not enough room for the larynx and the soft tissue in the mouth .
- The soft tissue blocks the larynx and restricts the passage of air.
- The nostrils of brachycephalic dogs are often narrowed (stenotic nares).
Other features that can help to influence the severity of BOAS that can be seen on the outside are:
- to much loose or/and thick skin
- thick short neck
- obesity

The 3 girls on the lowest row are of a leaner type with a thinner skin and longer skull than the girl above with her more molossian morphology and short head who has BOAS + CMSM.
