How much liquid worm medicine do I give my small dog or puppy?

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Baby Girl is very cute. First, I would make sure you get an accurate weight. Once you have that here's how to calculate the amount. (You should get a dosing syringe so you can measure cc's or ml's) One teaspoon is 5 ml so 1/2 teaspoon is 2.5 ml. If she weighs one pound her dose would be 0.5 ml orally. So take her actual weight in pounds and multiply it by 2.5. Then divide that number by 5 and that will be the number of ml's or milliliters (cc's) that you should give her. Great question. Good luck with Baby Girl. She should be dewormed 3-4 times and the dewormings should be done every 3 weeks.
