I have a yorkie silkie named Sammie. She had Pups on 16 Dec so now we are at day 2, she appears restless like she is nesting now, she is scratching the recliner, ...under the bed under the tables, like she is digging for gold. Puppies are healthy, she saw vet yesterday to make sure no residual pups or afterbirth. Vet gave antibiotic cepalexin, just in case. Her calcium levels are fine. Any ideas for the restless behavior??

Thanks in advance for any ideas and advice
