answer:Since it’s not chronic stress, but stress of-the-moment, I don’t imagine it would be harming you. Not pleasant, but probably not harmful. If it’s bothersome, this article provides a nice overview of possible reasons behind it, and some strategies to alleviate it. My dog barks at night more often when he’s not done much during the day—sometimes with my schedule I don’t fit in enough for him (he’s very high-energy). Playing with him usually helps. He also will bark at the door, or when he thinks he’s heard something. I’ve learned that the most effective way to get him to quiet down is to follow him to what he believes is the source of the sound (or as close as we can get and still be indoors) and make a show of looking with him to check out the situation. I’ll pat him and say “thank you, that’s enough,” and we’ll both walk away. I’ve decided I don’t mind doing that sort of ritual with him (actually, I think it’s kind of fun), and it seems to give him a sense of “okay I did my job and she checked it out and it’s all good.” You may find similar reasons that your dogs bark, and similar routines with them. Or you might try some of the techniques suggested above—whether ignoring their barking and rewarding their quiet, or tiring them out mentally/physically, or training the dogs to bark and quiet down on cue.
