Pure Bred to Mutt: A Change
Over the last few decades, and in particular the last few years, there has been a lot of discussion about the differences between the pure bred dogs and the mutts, which have usually been shunned from official circles. Some of this has been behavioral differences, and some are just physical differences, which can also include health problems, such as hip dysplasia, which is a common problem in many larger pure-bred dogs.
The pure bred dog generally has specific, predictable breeding quality. There are guidelines from the American Kennel Club, among others, that determine the qualities needed for papered dogs that can be shown in official circles. There are certain qualities that particular breeds are expected to have, and some of those qualities are mainstream enough that a person can determine from how a mutt walks what genes from what breed they have (For example, the German Shepherd walk) .
Owning a pure bred dog used to be, and in many ways still is, the goal of dog owners around the world. In old times, owning a pure bred dog was considered a sign of wealth and high status.
