    13.5 kgs.

    Step-by-step explanation:

    Here we have to find conversion factor of lbs into kg.

    For this we use the given information.

    Given that the weight of a dog is 20 lbs and also 9 kg.

    Hence we have conversion factor as

    20 lbs = 9 kg

    Or 1 lb = 9/20 = 0.45 kg.

    Using this, we find the 30 lb converted into kg.

    For 1 lb, equivalent kg = 0.45

    Hence for 30 lbs equivalent kg = 30 (0.45) = 13.5 kg.
