Pups are edging up to 3 weeks. When they reach that age, activity levels will change.
They now have toys in their whelping box and they do nose them and lay on them or sleep in beside.
One particular is getting up on all 4s many times a day. She will be the 1st to completely walk.
Be sure to check out the videos.
They did not need their nails done yet. They will get them done again when they start catching on to the blankets etc.
