I happened to see some of this weight pulling at the Royal Adelaide Show last year. Up until then I didn't even know it went on. It was completely *appalling* I could never imagine subjecting my beloved dog to that, and am amazed anyone would want to ...
Ruin, I saw Pedigree Dogs Exposed last year too and couldn't believe it. I knew some dogs had genetic disorders but didn't know to such a scale, and the attitude of some of those breeders really seems crazy.
If anyone else watches it, I'd LOVE to hear what you thought of the Rhodesian Ridgeback breeder...

A friend of mine saved one about to meet a dreadful fate for having the audacity to be born without the ridge (turns out the ridge actually signals a spine abnormality)
Anyway, Catalyst did a follow up to it from an Australian point of view if you're interested, Ruin.
