I'm not saying that China is an "animal-loving country," but for that matter, how are places like Europe or the US, where billions of cows, chickens, pigs, etc., are slaughtered every year? Because we keep dogs as pets rather than cows, that somehow makes us superior? Weak argument.
Again, there is no proof that Covid-19 came from China, or Wuhan in particular. What we know is that Wuhan is where the first outbreak occurred. There is no definitive proof that it originated in China, or Wuhan, although it's very possible; we don't know the true answer yet.

The initial investigation in Wuhan will inform longer-term studies into the pandemic’s origins, which could take investigators outside China. “Where an epidemic is first detected does not necessarily reflect where it started,” the WHO report states, noting preliminary reports of viral RNA detected in sewage samples before the first cases had been identified.
This statement could refer to a study1, posted on the preprint server medRxiv without peer review, which retrospectively tested Spanish sewage samples from March 2019 and found SARS-CoV-2 fragments, says Raina MacIntyre, an epidemiologist at the University of New South Wales in Sydney, Australia. “If this study was correct, we have to ask how the virus was in Spain in March last year,” she says."
