Advice on Buying a Puppy?

Mainly what you said. I would add besides the obvious of researching the breed you are interested in, do as much research into the breeder. There is ton of info easily available on the web to find out what exact health testing should be done, what the breed standards are & all the rest usually on that breed club site. Asking a question or two on here doesn't count as real research. Buying from your neighbor, family, friends of friend, etc are not who you buy from unless they are actual responsible breeder. Plan ahead for future vet visits/emergencies. Pets all cost money & are a luxury.
