Almost half of Pugs, French Bulldogs and Bulldogs suffer from Brachycephalic Obstructive Airway Syndrome (BOAS)

Short nosed or Brachycephalic dogs such as Pugs, French Bulldogs and Bulldogs suffer from Brachycephalic Obstructive Airway Syndrome (BOAS) which can cause health problems, breathing difficulties and even death. Veterinarians have conducted research to try to determine if there is a way to predict which dogs will suffer from BOAS, (almost half the dogs in these breeds are affected). By determining which dogs will have BOAS, breeders can try to eradicate it from the breeds that suffer from it.

In 2015 researchers at the Royal Veterinary College, University of London determined that dogs whose muzzles were less than half of their cranial length and dogs with thicker necks were more likely to have BOAS. However, they did not feel that this was a reliable way for breeders to select dogs for breeding.

More recently a new study by researchers at the University of Cambridge tried to compare neck girth with chest girth and muzzle length to see if that could predict BOAS. However, they found that it was not easy to measure dogs and it was not reliable. They did suggest that breeders should not use dog with very short muzzles, wide faces and thick necks for breeding.

Dr. Nai-Chieh Liu one of the researchers suggested that breeding for open nostrils is most likely the best and easiest way to improve these breeds. Researchers are going to try to find a genetic marker for BOAS to help improve  Brachycephalic dogs to improve breeding programs.

People who own one of these breeds should have their dogs checked yearly for difficulty breathing even if the dog appears to be OK.
