I’ve owned a number of Pugs and currently have two. This entire subject of unhealthy life is being thrown around with a VERY broad brush. Should you take no concern with how you feed and exercise your Pug (or any other animal or human?) of course you wind up with an absolutely compromised creature.
It truly is a sign of how much time we have on our hands that THIS is the focus of attention. Start a list of every canine that is susceptible to some form of malady and let’s see what’s left ? Caring for a Pug is quite easy if you simply pay attention to their needs and don’t expect them to be something they are not.
Absurd…….
My gran had 4 over the years. The last two were given to her by someone who was at the time a top pug breeder from another part of the UK. She got those dogs so long as she didn't let on where they came from or move near to her. Reason? They had too long a muzzle. A throwback that she was too embarrassed to have linked to her. They were clearly pugs but had a bit of a nose sticking out. As a result they didn't snort or struggle to breathe. They were fairly healthy, except for issues with too short legs, tendency to be overweight, unable to walk far (a positive for my grandparents).
Owning and loving the little characters simply doesn't preclude the fact they've undergone selective breeding to achieve a made up breed standard that has driven a skull deformation that is tantamount to cruel. Bear in mind they'll still be characters without the bent in skull of they bred that out of them. If we went back to the breed standard of Hogarth's time we'll still have the Pug character but within a healthy dog.
If you want to see the issue Google Pug skulls now and then or something similar. I saw the change over little more than a hundred years.
PS the Pug breed is an old breed from China. It's really only in It's more recent history that the skull issue has happened. What's wrong with going back to the original breed standard that was actually healthy. It's more absurd to want to stick with the unhealthy breed standard.
