DescriptionSavegame:
http://dffd.wimbli.com/file.php?id=8863 [^]

In the save, one of the horses can be seen trying to run away from the trader before being teleported back, which repeats every time the trader makes a step.
When the horses reach the depot, they crawl away for a while before returning.

Whoops, forgot to mention the version: it's .40.02.

UPD: It appears that animals behave that way when dragged in general, so this bug is simple to replicate: pen/pasture an animal and observe its movements while a dwarf is dragging it.

I can confirm this happens every time dwarf is dragging an animal to cage or pasture.
It seems to be related to the new mechanics of walking speed, so for each step the dwarf walks dragging the animal, the animal is able to do 2-3 steps trying to "escape".

It sounds like the game is missing checks for "is the creature being dragged" to prevent it from moving on its own.

I've also seen this happen in 40.03 with human traders.

This also happens simply when pasturing animals. Easily reproducible.

Perhaps this bug summary could be made little more informative?

Edit: Thanks Foot.

This can result in a deadlock situation when the animal wants to move in the same direction as the "leading" dwarf in a narrow hallway:

1. Dwarf takes a step forward; animal is teleported to dwarf's previous location
2. Animal takes a step forward onto the dwarf's tile, switching places with dwarf (returning dwarf to his previous tile)
3. Dwarf repaths (red question mark) and returns to step 1
