Because
if you administer new types of drugs to people without having any idea of their safety, and someone dies, you're guilty of criminal negligence or even manslaughter?

You rely on her disconnectedness from that dog's suffering for your modern medicines. Stop taking medicines that were ever tested on animals, or stfu.

No
It is a legal requirement to test all drugs for human consumption on animals.

Pregnant animals, in fact, to avoid a repeat of the thalidomide disaster that so many anti-testers try to use as an example of why animal testing isn't needed when in fact it proves quite the opposite. It wasn't the animal testing that failed, it was the fact that the right tests weren't carried out.

edit: And if you are going to use your argument that a legal requirement is a choice we make then I am going to call bullshit on your argument and stop engaging with you because you are clearly a moron.
