Pull back legs from their fur covers. In this case they are merely springs/looped metal, other toys may have flexible plastic coated metal.

You may have to trim/cut any filling that may have stuck onto the wire or springs to free the legs.

Unpick 2 small stitches keeping the tail in position, then free from it from fur cover.

Once tail and rear legs are free you can then pull the front legs free from fur cover. Trim filling as necessary.
