I do not personally agree with cross breeding dogs. I think they are cute, but their are PLENTY of them in shelters.
Also, I feel bad for the people who believe that these are pure bred dogs, and then pay HUGE amounts for them!
Just about as bad as these skeezy people claiming to have "teacups"... Makes me want to scream!
I think the only responsible reason to breed is for the betterment of that breed... And I do not consider a mixed/cross breed to fall into that category. Sorry just my opinion.
But I guess if it was not these mixed breeds getting bred, I am positive these BYBs would be breeding purebred, just the same... As long as people buy them, they will keep breeding...
