Argumentative Writing

I personally think that they shouldn't test products to test if they are safe for humans because if they were to test something like a drug and it kills or harms the animal did they disservice that pain or to die of cores not,think of it like this say you have a dog and some one says hey we have mad a new medicine that might cure cancer and your dog has cancer lumps every can we test it on your dog,and the medicine kills the dog the dog did not disservice that, animals have feelings too they can fell pain there just like humans but you don't test them on humans, I think if you really want to test it test it on your self
