Kids and their critters

One last photograph from that day in 1940. From left to right we see Alma, Ruth, and Wayne. Each one is holding a puppy (at least I think all three are dogs, not rabbits): Alma’s is completely white; Ruth’s, white with a dark face and head but a white stripe down the middle; Wayne’s, dark all over.

Does anyone remember the names of these puppies (or if they are puppies)?
