== Copyediting notes == 

 I was asked to copyedit this article, and I am doing so, but I think some fundamental rewriting is in order.  I have comments here, which i will be adding to as I go through the article. 

 1. What makes Miklosi such an expert that his book is used more than 20 times (with on page numbers) in the opening sections?  As a note, it was more, but there are some paragraphs taken entirely from Miklosi, so I dropped the line-by-line cites in favor of a single paragraph end cite.  For such a generic article, one source should not be relied upon so heavily for information in a given area. 

 2. I will leave it up to the regular editors, but I believe that the etymology section has no place in this article.  This article is about the animal, not the word, and the etymology section really sidetracks the article.  Since it's useful info in some sense, I haven't hacked it out, but I suggest that some discussion be had on this item amongst the regulars. 

 3. There's a lot of circular discussion in this article.  Many items come up multiple times, but in different sections.  Again, I would say that the regulars need to decide on one place to reference information, and leave it in that place within the article.  For example, the divergence comes up at least three times, and is only discussed in-depth once.
