I'll be sending you shortly to a blog I love dearly, Two Nerdy History Girls, but here's why: They have already written a fine long post on the ship's dog of the English ship the Mary Rose, which sank in July of 1545.
As archaeologists were excavating the wreck site (is it still "excavating" if it's under water?), they found a number of items, human remains, and next to a cabin hatch, a dog skeleton. She was a girl terrier. The archaeologists called her Hatch.
Here's the website for the Mary Rose's museum. Be sure and check out the page on the crew, though Hatch isn't mentioned on there yet that I can see.
