This morning at 9:30 AM central, I logged to my breeder’s journal that Mr. Yellow took 5-6 steps with all four legs extended. To my knowledge, he is the first of his siblings to take steps.
This is a 6 minute webcam video from the whelping box this morning. At the 4:40 minute mark, you can see Mr. Yellow do his thing. Not quite as many steps as he did earlier, but you can see he’s getting up and walking.
