All dogs may be categorized in the umbrella Canis familiaris, yet they differ radically from breed to breed. I’m not just talking about physical traits, either. Anybody who has owned dogs of different breeds will know that the inherent qualities of the dogs, such as mental ability, instinctual reaction, personality traits typical for the breed and general temperament (to name a few) differ greatly.

BPs, on the other hand, will exhibit the same BP traits no matter what morph they are – because a BP morph is only a superficial (aesthetic) difference between snakes. When you mix breeds of dog, you get a mixed bag with who-knows-what inherited and/or warped from the sire and dame. This point is discussed widely in dog breeding circles. The following points were made by one long-time breeder:

1. Purebred dogs are not mixes, because they breed true. That means that you can predict what they will look like, grow to become, act like, and what capabilities they will have from the moment they are conceived. This is NEVER the case with a mixed breed dog...you have no idea which genes you will get from which parent, nor which they will resemble, nor which breed in their background will most influence their temperament.

It takes many, many generations of selection to breed true. You can't breed one litter from two different breed parents and say that you have created a "new breed".

2. The purebreds we have today were never "designer" breeds -- they were never developed specifically for sale to the public as pets. They were never bred for "marketability". They were bred and developed for a PURPOSE -- a better hunting dog for lowland game; a better herding dog for the rough, hilly terrain of the Shetland Islands; a better Guardian for a tax collector; a better sled dog to ensure the SURVIVAL of a native tribe.

The "designer dogs" being mass-produced and sold to the public like Ugg Boots or Hollister jeans these days were developed for no noble, useful reason. THEY WERE DEVELOPED TO MAKE SOMEONE MONEY AT THE EXPENSE OF THE DOGS INVOLVED.

3. If people research their breeders, they will get what they pay for with a purebred. The same is NEVER true of a "designer" mix.

While all dogs may be members of Canis familiaris, they are not equal.
