How do you measure worm medication out for a dog?

Any canine worm medication will come with a measuring instrument, either a scoop with lines or a syringe. Based upon your dog's weight you figure out how many scoops or how much to pull into the syringe then administer to your dog.

If there isn't a measurement instrument, I would suggest not using that medication on your dog - it may not be what you think it is.
