“Apollo was there for me when I had my lows of lows,” Rachel says of the pup, whom she “fell in love with” at the shelter.

Though always loving and protective, there was one day when Apollo left his snout resting on Rachel’s abdomen for an extended period of time. She snapped photos of the sweet moment and remembered finding it unusual for him, but didn’t think too hard beyond that.

Three weeks later, Rachel’s life changed forever when she had a positive pregnancy test, and nine months later, welcomed her son, Donovan.
