Dogs are dogs. Military dogs are properly trained property. Giving them anything more would mean (eventual) human rights to beasts. You know the libtards are itching to give “human” rights to chimps and dolphins.
Yes, they are property, but animals have always (generally) been viewed differently than inert property under our system of law. You can hang your pillow on a clothesline and beat it with a metal rod all day long. Do that to your own dog or cat, and you'll be explaining yourself in front of a judge. Similarly, many state laws put the theft of a horse or livestock in a category more egregious than the theft of say a TV or canoe, even if they were of equivalent monetary value.
People may attach sentimental value to an object, but people form emotional bonds with animals. Similarly, most inert property can be had for the duration of its owner's life and passed on to posterity if adequately cared for. Animals, as property, are ephemeral and so when an emotional or sentimental attachment is formed, there is an added impetus to maximize the value of the attachment, knowing that the bond will sooner or later be dissolved by the death of the animal.
