 | I'm not sure what type of paper you are doing so these may or may not be helpful to you, but I did a review paper on morphological and behavioral changes in domestic dogs for a class last year, below are some of the references I found on the topic. Some of these are more about behavior though as my paper was about both.
You also might find this link interesting, it shows historical photos of various breeds: http://www.messybeast.com/history/history.htm
The paper "Molecular origins of rapid and continuous morphological evolution" has some interesting information on changes in skull structure of some breeds over time, and associated genetic factors (mostly involving tandem repeats). If you want more references for this I also did a paper on tandem repeats and canine skull morphology for another class a few years ago and I can search up the references I found then if you're interested. I know that same paper was on that list too.
