This commercial, starring Sarah Mclachlan, asks for viewers support against animal abuse, though it seems like their argument both begins and ends there. The commercial contains many domestic animals, cats and dogs mainly, and frames them so that they appear sad. Sarah Mclachlan then comes on screen and explains how these animals are suffering. By doing this we can gather that the commercial works on the argument that an animal's rights are given because of the ability to suffer rather than their intelligence or ability to speak. The ad has no mention of any kind of animal that isn't a dog or a cat. Chickens, pigs, cows, horses, and other animals are completely invisible to this ad. This puts major emphasis on the common domestic animals, raising their importance and possibly implying that their suffering is more important than service or farm animals.
