Folks I'm pretty sure the image being mocked is an actual joke, not, like, a really poorly-made list of actual companies. When you mock an intentional joke, the mockery points back at you.
The primary testing phase is of bad/rotten/moldy foods done before any lab analysis of the food is done. It's almost always lethal and is done to save money in lab tests.
Why do they do lab analysis anyways? Don't all the other breeds have similar sensitivities? And I'm sure a science room thingy test (I forget what it's called,) would be cheaper than a whole dog???
This sort of seems like a long sneaky way of saying Palestinians are animals being tested on by Israel. Maybe the joke in the top bit is lost on me but I'm not a fan.
