The whole list is disgusting. The 2003 Baker/Pyke dogs' SPCA death sentences were "fearful and impending blindness". That would be #9 and #18.
Imagine if we treated human beings like this. We wouldn't have the healthcare crunch that we do. The politicians would like the money saved...there would be empty beds in psychiatric wards, we could just euthanize anyone that had a cold that showed up at hospital emergency wards, parents could do away with their children if they cried when left at daycare or if attempts at potty training failed, Attention Deficit children would be a thing of the past as would people with MS, Asthma, Chrohn's Disease and on and on.
What a neat and tidy world it would be....wouldn't it?
One other thought....
Humans that abuse, maim and kill animals get very light judicial reprisal, but animals deemed "aggressive to cats, dogs, humans" die for their crime.
