Stress. Along with separation anxiety, general stress can also lead a dog to start pooping in the house. Like with people, a dog's digestive system is sensitive to big, sudden changes. Life event triggers, for example, like moving house can cause your dog to become stressed.
In many cases, however, pooping at night could be related to a medical issue, and your dog could be in pain.

Dogs have a natural instinct to relieve themselves where they have done it before, so if your pup can smell her urine or poop, she will recognize the area as an acceptable potty place and relieve herself there again.
This is nothing to be overly concerned about, nesting is instinctive — long before dogs were given soft beds by their human companions they would have to find somewhere outside and make it as comfortable as possible before sleeping.
Medical reasons a dog may break housetraining and poop in the house include tummy troubles caused by parasites, food allergies or illness, cognitive impairment, and bowel disease.
Often these signals are in the form of changing their routine or doing something that is not at all in their character. If a dog is suddenly pooping in the house, he may be signaling that something isn't right. This can be stress-related or related to other health issues."
