I cannot believe that anyone is really surprised by what the BC SPCA is doing by bringing in Pitbull puppies from Ontario.
Cute puppies are easy to sell. Puppies have no baggage - they haven't been left outside on the end of a chain yet.
Adult dogs are not as cute and might take some extra care to help them lose the baggage they carry by having been neglected.
This is why the BC SPCA sells puppies - they are an easy product to move. And in this instance they managed to garner some good media coverage to boot.
