Trade Me has announced it is banning the sale of pugs, British bulldogs and French bulldogs starting in March.
The decision came from concern for the suffering they face due to brachycephalic obstructive airway syndrome (BOAS).
BOAS is a condition which affects dogs and cats with short noses. Their shorter airways prevent the animals from being able to breathe fast or deep enough when exercising, stressed or hot.
