My dog eats entirely too fast - as if she hasn’t eaten for days. How do I correct this behavior (read below)?

My English’s Springer Spaniel, who is a little over six months, eats every meal like she hasn’t been feed for a week (we feed her twice a day and the correct amount according to her weight). She eats so fast that she sometimes starts choking a little. Is there anything I can do to correct this behavior?
