What age do you start checking for Heartworms? Chance hasn't been tested because the vet said something along the lines of he wasn't old enough for them to have become adults and that starting him on Heartguard would kill any if there was any. (Something like that) That was a few months back, he's now 13 months old so I'm guessing it's about time for a test? How often do you check for it?
