Considering getting a dog? It's worth doing your research — not just because you want to check out each dog breed's temperament and suitability for your lifestyle (clingy dogs will not cope well if you travel five days a week and leave them at home), but because of how likely they are to have health problems. Dogs were domesticated around 10,000 years ago and have been a firm part of human civilization ever since, with hundreds of different breeds around — but as trends for various features have come and gone, certain dog breeds have experienced health issues that come from pedigree breeding. The results? Over-bred animals that suffer from genetic health issues from centuries of breeding selection.
Just because a feature on a dog, like a squashed face or wrinkles, looks cute, doesn't mean it's good for the dog's health or wellbeing. Many dog owners will experience that conflict, particularly if they own purebred animals that don't have any mixed traits from other breeds to mitigate these health issues. That sweet snuffly noise from a snub nose may turn out to be a painful and expensive issue.
