[QUOTE="Don't get me wrong, my dogs shots and everything are all up-to-date and if anyone challenged and called my vet, they would say the same, since they seem to be there every couple months or so. But when I first found out about the cert requirement, I believe it said you had to have the certificate dated no more than two weeks before travel. If I travel to Mexico twice in the same month, once at beginning and once at end....to me, that's a giant PITA getting three dog certs twice in one month and spending, what, $150-200 total. But if my travel is a 6-12mos or so apart, yeah, I'll probably get newer ones again, in case something changes or whatnot and just to be somewhat current.[/QUOTE]
Sorry for the mess above, but the "reply" feature seems to have a glitch. Anyway, regarding your travel pattern, mine is about the same: 1 to 2 times per month. What I was saying is that I simply update the dog certs (for 2 dogs) every 6 months. I, too, have seen the statements that they must be dated no more than 2 weeks prior to travel. But apparently -- based on what I heard, as well as my own experience -- they will be honored at the Mexico border for up to 6 months. I recently put that to the test in November. Was stopped . . . showed them the rabies certificates in addition to the "small animal. . . " (pink) certificates which were dated in August. No problem.
