Happy to explain it. They are being downvoted because you said it yourself, not everyone has the same experience so this person saying parvovirus is literally “not that big of a deal” is so narcissistic and main character syndrome that it’s a bit disgusting, especially considering the numerous posts in this sub where people have lost their pups to the virus. Also as a former vet tech I can assure you in parvovirus heavy areas there are still “it’s not that big of a deal” idiot owners who cause the needless suffering of their puppies due to attitudes like this. Hope that explanation helps you both develop some empathy around the situation.
