  You will probably find certain breeds within the purebred category that are "sicklier" than other breeds.  On the surface, it would look like there is something wrong with the breed itself, but with a little more investigation you will learn that the breed is too popular for it own good.  When a breed is extremely popular, you get breeders who are breeding only for profit, and not to produce a beautiful healthy dog.   Yorkies would be considered one of the most popular, and most genetically at risk breeds.  That's why it's extremely important to find a great breeder when you are looking for a dog that's in the top five in popularity.  Breeders, who breed lower rated dogs in popularity, are probably on the whole, doing it primarily because they themselves love the breed, and want to do right by it.  |
