We got our Rudy from one of these. Didn't know it until we got there. Anti-vaxxer, internet researching, didn't feed their dogs dog food, didn't beleive in deworming and gave the animals some soer of white crystal shit, didn't beleive in any type of, you know, proven science.
Not to be gross, but Rudy had the shits for 3 days after we got him. He wasn't eating properly. He needed deworming. We took him to a vet ASAP because, you know...science and shit.
