Ringling

Recenty Ringling magic people or circus appeared on The Early Show. Now with small dogs. A few montsh back there was a case with Ringling, they were accused of animal abuse. Shackeling elephants by the ankles when they weren't performing or when they were traveling which at the most lasted 100 hours. Two workers from Ringling, are now somehwat heros, in the eyes of PETA. They were the "whistleblowers and spilled the beans about all of the animal cruelty they had witnessed.
So, my question is, why would Ringling want to start using small dogs, in which people can obviously tell they are not fed or treated right, in their shows? Many of the dogs they use have to walk on their hind legs for super long periods of time, causing, arthritis, which is not fun. And having experianced a dog with bad arthritis, the dogs can't do much, so they get fat, and are put down. Many complaits come to PETA about dogs being in circuses. So why would Ringling want to make the mistake of using dogs in their shows?
