Brooks called Andrea Bertolucci, a veterinary advisor for Marley's Mutts- and Bertolucci reopened the clinic to examine Snowflake.
The puppy's temperature was hovering around 94 degrees - well below the 101 degrees considered healthy for her age.
But Snowflake wasn't letting go of her first real chance at a life. After being treated and given fluids to fight dehydration, "she just progressively got better and better," Brooks says.
Then Snowflake entered the second phase of her return to the living: a foster home.
That's where a dog named Massie, a permanent family member there, knew exactly what to do.
"She's totally taken on kind of a mom role," Brooks says.
