You've not seen an 'unhealthy homeless dog'? Melbourne has certainly changed since I lived there, then! Half-starved bitsers rooting around in rubbish tips, too cunning to be caught by the dogcatcher, not quite cunning enough to keep themselves properly fed. So damn sad. I suppose in these days of covered tips, it would not be so likely.
And here in the bush, it is not uncommon to come across bodies of dogs that have been dumped on a bush track off-highway and left to fend for themselves, they usually starve to death. People just plain suck sometimes.
