I saw this post/article on my facebook page and had to share it. it shows how much humans have valued their pet dogs and little has changed since the time of the Ancient Greeks. This link will take you to the original post but the title pretty much sums it up: 9 Touching Epitaphs Ancient Greeks And Romans Wrote For Their Deceased Dogs.
You can learn a bit more about dogs, their evolution and their anatomy through my skull of the month page on the domestic dog. I’ve also written a page about evidence of dog domestication in archaeology which goes quite nicely with the article!
