I have one question to those that say that all purebreds are mutts. I agree that the yorkie is a descendant of the Scotch terriers (consisted of many breeds) there's no argument there. But, after a while you can't keep claiming a certain descent right?
For example, let's talk about people. I think I can claim Mexican heritage because both my parents were born and raised in Mexico. My grandparents, great grandparents, great great great grandparents, and great great great great grandparents were born and raised in Mexico. But, looking at genetics you can see there must be some Spanish blood in there somewhere. Can I claim Spanish heritage? Probably not. I know nothing of the customs, I don't have their sexy Spanish accent. I know that after a few generations, my children's, children's, children's wont have a connection to being Mexican.
Does it matter now that I'm 1/1563486 part Spanish? Argentinian, or whatever? Not really. I'm Mexican.
I think similarly it happens with pups. They at one point were Scotch Terriers mixed with, whatever. The original craftsmen of the breed bred for a reason. They wanted, well.... I can only guess what they wanted. A compact, fearless, dog to keep the rat population down.
Today, if someone was to mix a two breeds with a purpose, I have no problem with it. They need a smart dog to guide the blind, that is hypoallergenic and is easy to groom, then ok. Breed goldendoodles. (by the way, totally made the last part up. I don't know why people breed goldendoodles) But when you think of Morkies, what purpose is there? Just to have cute puppies?
For the record, mixed breeds dogs are as awesome as purebreds. They all deserve wonderful loving homes. Neither should be bred if not for the betterment of the breed.
Ha! I'm going to unsubscribe to this thread because it's just going to keep going in circles.
