I heard this from my dad decades ago too - but I don't think mutts are any more or less likely to develop a problem than a purebred. It depends on the ethics of whose doing the breeding. Good breeders work hard at trying to eliminate know genetic flaws by carefully documenting breeding. the ones I know are concerned about passing on the best traits of the breed both physically & tempermentally. Breeding is more likely to be random with mutts. The biggest culprit are bybs who inbreed & overbreed, & breed dog with known problems.

*I also heard that cats would smother babies & kill them . I put them both in the "old wives tales" category.
