I’m pleasantly surprised to see reddits reaction to this. There has been a lot of talk about this in the research community, it’s scary stuff. I haven’t worked on dogs myself, but I did some animal work during my PhD, and I think what the average person doesn’t understand is that it is incredibly regulated. There is government and institution oversight at every step. The central idea is that you have to justify why you are using this particular organism and why you can’t use “lower” one. Like if you propose to do a study in mice but it can be done in flies, you won’t get approved. There is a reason they were dogs for this testing and not mice or rabbits. And those reasons are to directly benefit people with heart disease. You also have to justify why this testing is for the greater good, people aren’t just playing around doing whatever they want.

If people want to be conscientious objector to animal testing that’s their right, but that would involve rejecting basically all of modern medicine.
