Okay I wanted this to be clarified. A few other people informed me on what the real story was relating to this comment:

"There were some dogs on a show on Animal Planet that went blind from a vegetarian diet (sorry I can't give more details because I forgot what show it was)."

Im suspecting this is what Aly was probably thinking of. On Animal Planet recently, (I taped this actually, because I remember hearing the commercial, plus I love the show, but havent watched yet, so I didn’t associate it with Aly’s post until my friend who saw it told me about it today after reading Aly’s post), on the series, Animal Precinct, there was a woman who took in stray CATS (not dogs) because she didnt want them to be homeless, and what she was doing, was feeding them like, a human vegetarian diet, of I think just potatoes and rice or something, so not only was that not nutritionally complete, but they didnt like it, so they were barely eating any of it. So they became really thin, and I think neighbours saw and reported it. When the ASPC went to assess the situation they discovered that she didnt really want the cats but she didnt want them to be homeless. She had way too many than she could handle in the first place, there were no litter boxes even. She didnt know that they needed taurine to survive (lack of taurine is what eventually causes blindness in cats). So they took the cats off her hands, and they all were treated, fed, etc and all of them lived. Only one was totally blind and then one other was partially blind.

SO, my point is, it was because not only were they not getting enough food, but they weren't getting the nutrients that they need, all of which are in vegan dog & cats foods like Evolution and Vegepet, etc. So I dont want anyone to think that situation is a common one. It was just a case of someone who didnt know what they were doing, someone who was naive and irresponsible.
