The first thing to look at is the numbers that are given in the problem. The next task is to get the numbers in the same units. Since the medication dose is 30 mg medication per kg body weight per day, let's convert 44 lb to kg.
44 lb (1 kg/2.20 lb) = 20. kg body weight
Now we can set up the problem to find the dosage. REmember that we are looking for mg of medication per dose. Keeping the final units in mind helps us see how to set up the problem.
20 kg body weight (30 mg medicine/kg body weight* day) * (1 day/24 hours) * (12 hours/dose) = 30 mg/dose
We can see that all the units will cancel out and get us the final units of mg/dose. When including the masses, specify whether they are medicine or body weight since they can't cancel out even if they are both in the same unit.
