This is happening consistently in my 1.17 world (with experimental features enabled). When I take a portal into the nether with tame dogs following me, they appear with me in the nether, but then when I go through a portal to return to the overworld, the game client crashes/exits. Logging back into the world, my avatar appears in the nether and the dogs are returned to their original position in the overworld.
