*bangs head against wall until it bleeds*
Like I always say, there is absolutely no reason in this day and age to be breeding pet quality dogs, especially mixed breeds trying to make new breeds. I suppose a "shorkie" is a companion dog. . .what exactly does a "shorkie" do that other companion breeds can't?
Click here to see a list of "designer dogs" being bred today. I'm bad at estimating but there are at many hundreds of them being listed there, and those are only the most popular ones. Now imagine each of the puppies you breed and then multiple all the puppies for each "designer dog" type. That is a LOT of unneeded puppies. While the same mixes of no lesser value are getting killed in shelters people like you are pumping more out.
The only dogs that should be bred are show dogs and working dogs, dogs that have a purpose, dogs that gain titles, dogs that are thoroughly health tested, dogs that are proven exceptional, dogs that fullfill their purpose (like exceptional BC herders), ones held to high standards for breeding so there are fewer litters and healthier puppies being produced. Those pets in shelters are dying every year by the millions because of BYBs and puppy mills.
You mentioned you can't be a BYB because you take your dogs to the groomers and give them good food (can't verify that, though, because I'm not sure what you feed), that makes those points good but does not change you from BYB status. If you breed pet quality mixed breeds in abundance without proper health testing like OFA, CERF, or PennHip, you are, in simple words a BYB, and depending on how many puppies you have, even pushing on a mill.
