The BCSPCA probably killed Tyson because he was an time consuming, expensive inconvenience. He was too much trouble and they could not be bothered to go the extra distance for him. If any animals that are surrendered to the BCSPCA have any special needs, you can be assured that they may be killed. The owner, after abusing Tyson, dumped him off not caring what happened to him. You would think then that the BCSPCA would make sure that they did not fail him as well, as he had been through so much abuse before. You would think that the BSCPCA would try extra hard to find him a home. But in the end they failed him also. But don't they feel bad about killing him? Does the BCSPCA have a soul??
