Shelters full of pure bred AKC dogs
Yes, sadly that is true and many (probably half) are from legitimate 'show quality' breeders whose puppies just didn't make the grade. All those expensive tests are unfortunately not a guarantee that a pup will be free of genetic problems. In fact, the dirty little secret is that all too often the offending genes cannot be seen in these tests. People return these expensive dogs at some point when they realize they are flawed. What do you suppose happens to these little problem puppies?
So, somebody can pay upwards of $1000.00 with absolutely no guarantee or $200 for the same result. Hmmmm. Many people would love to have a pure bred dog because of the characteristics of the breed but want a dog they can afford.
Many 'throw away' dogs have great potential as do many of 'throw away' children. Sometimes the blood line just doesn't matter.
