Lea Lea day 43

Today I saved two cine films showing that some bones have started to calcify. We see clear spine calcification and partial ribs and limbs. We look at two different puppies on these short clips…fascinating to see how they have developed over 42 days.

We see puppies heartbeats and lots of movement.

All appears to be progressing well and over the next few days the calcification will be complete. It’s really interesting to see how some puppies are slightly further on than others; a lot can happen in one day and this shows that fertilisation does not always occur simultaneously.
