US dog obsessed with newborn baby gently rocks her to sleep

A boxer dog rocked a newborn baby sleep by nudging the bassinet with her nose, although the pooch needed to be told to be more gentle at times.

The dog, named Cleo, joined the mother one morning as she was rocking the baby to sleep on April 30 at their home in Oregon.

The mother said: "Cleo loves her new human baby sister and has continued to check on her while she sleeps.

"I had to command Cleo to 'be gentle' as I was worried the bassinet was getting rocked too high."
