It is amazing sometimes to see the amount of torture a plant can take and still survive. While in the vegetative state you can bend, break and cut and they just seem to adjust to it and go on, but usually people wait until the plant reaches maturity (the first alternating nodes) before they attempt topping or FIMing. Your plants will try to survive the attack, and if they do, they will be ok... just permanently changed in structure. You will get 2 main trunks at the break, and being low on the plant right now, you have the chance to make a very dense bushy plant out of this eviscerated victim of canine foolishness. You will not get slow growth in the future from this, but you will get a delay in vertical growth for a week while she readjusts to her new situation. Keep in mind later that you are now supporting 2 main kola's, and her nutrient needs will increase correspondingly.

But then there is the dog to consider. Your puppy apparently thinks that the taste of your plant was interesting... take precautions so that this can not happen again. Keep pets out of the grow area... you don't need them dragging in critters, pollens and wandering among the plants, nibbling here and there.
