That is funny to me, I own 2 pit bulls and one of mine decided to taste 3 of my sprouts, I got pissed but dogs will be dogs, they are now banned from the grow room now the patiantly wait by the doorway and watch me.
At least your dog didn't kill them, may have even helped by topping them for you, looks like it will bush up nicely.
Also today is summer solsis so you don't really need to put them in the shed they will start flowering naturally in about 2 to 3 weeks I would just let them go naturally.
