I am a mutt and proud of it. I don’t intend to trash talk the purebred dog but for this week’s Pet Column topic I thought you should be aware of the impact that the demand for designer dogs (crossing purebreds with other kinds of purebreds) is making upon all dogs. From overcrowding shelters with unadoptable “designs” gone wrong to dogs living a life of suffering because of their failed “design”, I can help you avoid these pitfalls.
