I unironically believe vets are the best doctors. Years ago our family cat contracted some form of cancer. He had a surgical treatment out of state for less than $1,000, the doctor personally called afterwards to check up and see how he was doing, and he made a full recovery within a week. $1,000 for a human wouldn't even cover the test to confirm whether you have cancer.My vet showed us this chart, said our cat is yellow and we should feed her less. And discussed how we should make sure there are no grains or any plant products in her food.
Doctors need to be allowed to do the same thing;
Vets also have access to a variety of drugs that can be useful for humans (I'm not just talking Ivermectin but a lot of the drugs on the WHO list of essential pharmaceuticals). And a good vet knows how to do EVERYTHING from performing lab tests, to analyzing specimens under a microscope to weight control to pharmaceutical application to minor surgery! My vet knows 100x more than any doctor I've ever met, and it's broad knowledge.
If I was diagnosed with a particularly harmful disease or pathogen, I would certainly talk to my vet about it and value his opinion above whatever a doctor says. Actually, the next time you have a health question, I would tell your vet your "neighbor's pet" is experiencing it and see what he says.
In the apocalypse, give me a good vet over anyone else!
