I cannot comment on Sagalouts' knowledge of what Irishwomen are like or not, so will simply note that, on the basis of my five years of Dublin life, I would claim that Kaybee is entirely typical-- once a daughter of Eireann is determined on a course, there is little that can stop her, and few would think of trying. In Kaybee's blog, she refers to graduate school outside Ireland and having worked as a bicycle courier, so her americanisms might originate there.
Upon reading through the blog, it is a signal lesson on the miseries of taking a dog on the Camino and, the more I think of it, a study of the unkindness of so doing. Still, as I can't read the dog's mind, he may even like it.
