I didn't like the way the dog knocked the little girl over and you could tell by her face she didn't like it either. Whoever was taking the video needs their head examining if they think there's anything funny in a small child being pushed over by an over excited dog!
The video was taken by one of the child's parents - and she was not hurt. http://oneforthehoney.com/apparently-jack-loves-bubbles-too/
I agree the parents should of moved the toddler away from the dog before blowing bubbles, but I do love seeing dogs playing with bubbles, but only when no babies/toddler's are around to get knocked over. I liked the video upto when the toddler was jumped on even though it was a accident.
