Simply Spooning
This puppy was quite excited to see his new baby sister. These two became fast friends (as you can probably tell by this picture of them spooning). The infant is currently the little spoon, but that will most likely change as she grows bigger.
If that isn’t the definition of a faithful dog, we don’t know what is. The mother must be pleased because the dog is temporarily taking up her duties. That infant appears to be at ease!
