Объяснение:
В английском языке у нас нет такого родового обозначения, как в русском, который позволяет нам разделить дополнительную информацию о человеке/явлении и т.д. по родам, поэтому мы просто используем по отношению к людям и питомцам "who", а к предмету, явлению, животному мы используем "which". Значит, говоря о наших друзьях, не важно какого они пола и количества, мы просто говорим "who". Всего доброго!
