Grew up in a very rural area, on an actual farm, so it wasn't unsual to find animal remains here and there. There's also a section of my parents' land where we laid quite a few pets to rest, so I'm sure that'll be a fun surprise for someone a few decades down the line. I've been fortunate enough to not come across any human remains outside of a lab so far, at least.

Poor dog, though :( Maybe you can relocate it somewhere better once you've uncovered most of it (I wouldn't recommend trying to burn the remains, bones don't burn that well and if there's any more of it besides the bones left the smell will not be pleasant).
