Yesterday, while i was jogging at the park, a small dog

Yesterday, while i was jogging at the park, a small dog started to follow me, and when i stopped for a short rest, he came near my feet and was licking my shoes I kicked him with all my power that he flew in the air few meters away from me, and dropped on the ground motionless. I resumes my jogging back again and didn't think about what i did EXCEPT TODAY, when something VERY BAD happened to me. I think this is what they call it Karma.
