How many fleas did the dog have after three treatments? ** After three treatments, the dog had 14 * 2 = <<14*2=28>>28 fleas.
How many fleas did the dog have after two treatments? ** After two treatments, the dog had 28 * 2 = <<28*2=56>>56 fleas.
How many fleas did the dog have after one treatment? ** After one treatment, the dog had 56 * 2 = <<56*2=112>>112 fleas.
How many fleas did the dog have before the flea treatments? ** Before any treatments, the dog had 112 * 2 = <<112*2=224>>224 fleas.
How many more fleas did the dog have before the flea treatments than after? ** Thus, the dog had 224 - 14 = <<224-14=210>>210 more fleas before the treatments than after.
