It's not just allergies. I'm partially sighted & have very little peripheral vision. Some people have brought their dogs into our office & there have been times where I have accidentally "kicked" the dog simply because I have not seen it on the floor (and was not expecting a dog there anyway).

I like dogs & don't mind having them in the office but I certainly think it needs to be made very clear where the line lies when it comes to "me or the dog" issues.
