There are those who simply find a specific breed more appealing. Either they think it's cute or the dog portrays a certain image. An image that they perceive for themselves. For some, its a status symbol. I also expected that a purebred would be without problems, both physically and behaviorally. Yes, of course purebreds can theoretically suffer from hereditary diseases, but my thought was, a "good" breeder would minimize this risk. Secondly, I feared that a mutt would carry a lot of "baggage" and therefore exhibit behavioral issues. Raising a puppy from the very beginning seemed to offer a greater chance of success.
On the other hand, mutts are said to be smarter and healthier, in general. I don't think that there is hard data to actually prove this, but it's safe to say that mutts have the potential to be just as smart as any purebred. And of course, they benefit from a wide gene pool which makes them less susceptible to genetic defects. But that is not to say, that they are somehow impervious to disease. Obviously. And with regards to portraying an image, its probably possible to find a dog that suits you. You just need to look a little harder. Mutts are considerably less expensive than purebreds. Last but not least, it comes down to compassion.
So, which do you prefer?
