I don't want to be cruel or anything but i think that they test stuff on animals 'cause if they didn't test ir it could have something that made us sick or even get cancer or some cerious allergy. I don't think they use young puppies on this. They might even get dogs from animal shelters, instead of killing them 'cause of the over population of dogs. For instance, here in Chile you can see at least 10 dogs in the street why? 'cause we don't have shelters here. Many people leave unwanted pregnant females on street and they give birth on the street. I think we use animals to test on products 'cause in here we have lots brands that there are in other countries. Sometimes animal testing isn't that cruel.
