American Hairless Terriers typically take a little time to warm up to new people. They are alert and will bark if a stranger comes too close, but once they trust someone, they're very affectionate. Proper socialization from a young age can help them feel more at ease with unfamiliar faces.

In my experience, they have a curious nature when meeting strangers. My pup usually barks a bit at first, just to let me know someone is there, but he quickly settles down and gets friendly. They really thrive on attention and can be quite playful once they feel comfortable. Just remember, consistent socialization is key to helping them feel more at ease, especially in different environments.

They can be a bit reserved but are generally friendly.
