I really like these photos I found in a Buzzfeed article. The captions by Kaelin Tully fit the photos almost to a tee.
My favorite images are
# 1–the dog who is admiring a butterfly.
#3–two pals with their arms touching each other,
#9–the 2 dogs who hug each other every morning,
#11–the kitten who sleeps on the dog every night,
#16–the dog looking after some baby chicks
#18–the dog who wraps his arm around a cat when they are sleeping
See the other 20 photos here.
