dave-i would check if there is a use by date on the pack before i would use.
i think most products are to much anyway,they have testing results where they gave 5 times the recommended doses and not much at all showed up bad,i also think that when i used bayer tree and shrub,which is like 6 times weaker than k9 advantage,i used the same icc per 20lb dog and had good results.
even the frontline package has the dose the same amout for a dog from 22-44lbs.that tells me that its pretty safe to mess up,a dog half as big as another gets the same amount????go figure
i been useing it and will continue,jus 1 male i have has a very short coat and he may get itchy for a day or 2 after i put it on.lasts a day or so,but its not due to the termidor cause the same thing happened with the store bought labeled stuff,just sensitive to it
gun is a t/c-14"barrel
