I had this a couple of times but I moved a few tiles and made my pet move a few tiles as well and I was able to dig it up.
Once I was on the wrong facet (Fel vs Trammel) but sounds like you were in the correct location.
I would tell you to try again by moving a few tiles with no pet out and once you get it up summon the pet but sounds like you tried this already.
Only other thing is if Pandora spawned something (tree, etc) that is blocking the chest from coming up.
