Two of the boys - well there are only 2 boys - have reached 1lb in weight. The boys usually do grow faster than the gals. As it is cold outside, I realize I need weatherstripping as the heatlamps are now on all day and all night.
As pups can't yet regulate their body heat, it is a must. About 2 weeks, the regulation occurs and so do the ears and the eyes. Pups are born essentially with their eyes and ears closed as this is still developing. They use their smell and touch senses to find mom. If she is outside of the whelping box they will start to stir as they can smell her. Their sense of smell is great.
They do practice walking before the eyes are open. it's a curious thing as they can't see where they are going but they can smell. Often you will see them walking along the wall using both touch and smell. Once the eyes open, it takes days - up to a week for their eyesight to get clear vs. blurry.
Pups are doing well. Cinnamon is a very confident mom. You can find her many times going outside, sitting outside of the whelping box and not worrying about Leti or Raven. I have good moms!
