  Revolution.. the flea preventative?I would just give it now, but change your dates for the future.  I would think it is not harmful to be a couple weeks late, but I would wait a month for the next treatment.
 The same for heart worm... don't wait, even more so in the summer.  My vet said they have to give a test if you miss more than three months before you should give another pill.
 
 
 I know with Frontline I read somewhere that is worked for 3 months for fleas, but not for ticks... so it was recommended to treat the pets every month.
 
 I hope that helps.
