You may recall that Lucy is the dog of Hay's parents, and Emma is the dog of Hay's sister. Both Lucy and Emma have the same dog father, but different dog mothers.

*mutter* I really thought I had a photo and accompanying post about the Lucy and Emma photos that are on my fridge, but I guess I never posted them. So, pretend you knew what Emma looked like before today.
