I am actually quite offended by many of the ill informed comments on this thread.
For the people saying they make a point of making dreadful remarks to pug owners (people and dogs who they know nothing about!) it really is a dreadful way to behave!
The pug as a breed is centruries old and there are tens of thoudands of people who own pugs having decided this is the right breed for them, not because they are supposedly fashionable. Ther are many very commited and concerned braders out there who do extensive health testing on their bereding animals in order to reduce the potential for health issues, of course there are poor or irresponsible being as well just like any other breed.
Like many pedigree breeds the pug is suffering rom the result of many many generations of a small genetaic pool, however with pugs the difference is you can see the results whereas many other breeds which are still just as troubled health wise the issues are not as obvious.
To tar the whole breed as unhealthy and all owners as unhealthy as irresponsible is plain ignorant.
Both our pugs are fit and healthy and very active little dogs, in the pug circle we belong to with over one hundred dogs only a small number maybe two ot three have any type of breathing issues and that tends to be lack of tolrance to heat, which a responsible ownser can make allowances for.
For anyone buying any type of dog including a pug the message needs to be th same, buy froma. Reputable breeder who actively tests for health and genetics!, but dont vilify a whole breed.
