So I know you aren't supposed to take your puppy to dog parks and unknown grassy areas because of the risks of diseases like parvo and such - but is it okay to take your puppy to see another puppy approximately them same age (1 week difference) if they have both received their first shots and are both healthy - or is this still risky?
