Zounds

Still as a statue, the dog didn't even turn to face her. The skin and meat of its face had been peeled back so that big metal fangs could be hammered into place. It was more for show than function, but Lily didn't care to test it, staying well away from the zound.

Zounds, or sometimes zogs, are undead canines of any kind, pressed into service along with the human stiffs. Animals were the first to be reanimated by necromancy, when people were still squeamish about the idea, and they've never gone out of style. Zogs are no exception, put to work as cheap guards or riot control across the world. Some armies even field them in great masses and unleash them across the blasted no-man's-land before a main attack.
Like many stiffs, zounds are frequently modified in ways that would be impossible to do with a living creature. Everything from hooked spines to catch a chased quarry to explosive charges imbedded within them, zounds find many different uses.
Even where living dogs might be preferred, most people take a 'waste not want not' approach. They employ living dogs until they die, then raise them as undead to go right back to work. A few families keep well-preserved loved pets around long after their death, but the smell tend to make this practice uncommon. Cheaper than even human lives, zounds are as much disposable weapons as they are undead creatures, in the eyes of their owners.
