The pups are developing quickly

All that pups body weight has increased by about 15%.  They are also able to spend time together, without their mother (see picture below). Even just yesterday, they always huddled up against Cassonade to take advantage of her body heat.  They are a quiet litter - not too much squeaking.  Cassonade spends all day and night with them.  She eats her meals in the bin.  The only time she leaves is to go outside to the bathroom.  She stands at the door and barks to let me know she wants out.  She races outside, does her business, races back inside and stands at the door and barks to let me know she wants back in.  This whole process rarely takes more than 1 or 2 minutes.
