<human>:  A dog is being treated for fleas. One flea treatment gets rid of half the fleas. After four treatments, the dog has 14 fleas left. How many more fleas did the dog have before the flea treatments than after?
<bot>: 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.
