Do Irish Terriers bark?

Yes, Irish Terriers do bark. They are alert and vocal and tend to bark to alert their parents of any unusual activity or to express their excitement and enthusiasm. However, they are not typically excessive barkers, and their vocalizations can often be managed with proper training and socialization. The Irish Terrier is a terrier, after all, and as such, they can be quite fond of their own voice. As with any dog, they can be discouraged from barking as frequently with proper training and exercise.
