This marks a change from previous conflicts. When the second world war dawned in London, owners rushed to kill their pets. The British government, mindful of looming food shortages, set up euthanasia clinics and told owners that it was "kindest to have them destroyed", to spare them the horror of war. So many cats and dogs were put down that some vets ran out of chloroform. Attitudes have softened since then. Westerners now treat pets almost like people. Four-fifths of Ukrainian pet-owners see them as family members.

“have +宾语+ done” 中的have是使役动词,过去分词作宾补。通常用于以下三种情况(你的问题属于第3类):
1. 请(让,叫,使)别人做某事;例如:
I had some wedding photos taken. 我拍了几张结婚照。
2. 使得……遭遇/经历……(表不幸、意外或痛苦);
Yesterday I had my wallet stolen. 昨天我的钱包被偷了。
3. 完成或解决某事(自己可参与)。
We must have this work finished by Monday. 我们一定要在周一前完成这项工作。
