Hunched over, her face pressed against the wall, Lana is a portrait of rejection.
She arrived in Toronto, Canada, when she was very young, the runt of a very large litter in Mexico.
"Lana was terrified of everything," Dahlia Ayoub of Mighty Mutts tells The Dodo. "She was literally the size of my hand."
Lana was kept in a foster program, which had her spending short stints with families until she could be placed somewhere permanently. There were no issues, Ayoub says.
Eventually, when Lana was five-and-a-half months old, a family stepped forward to give her a real home.
And then those guarding issues - from when she was a puppy and had to compete with siblings for food - suddenly surfaced.
"She snapped at the mom," Ayoub explains. "And they decided because they have kids in the house to bring her back to boarding."
Ayoub describes Lana as "silly, sweet." She's great with other animals, and the above incident was the only time her guarding instinct surfaced. Yet, Lana was returned to the kennel.
"She just shut down," Ayoub says. "It's almost like her world shut down."
For a whole day, Lana was unresponsive. Not even the shelter volunteer who walked Lana could move her.
But for dogs especially, hope has a way of springing back again.
Ayoub, her lifelong friend, visited Lana the next day.
"I wanted to see if she would be scared of me. I went back there and said, 'Laaaaana! Hey, what's up?'"
Lana flew into her arms so fast to bury her with kisses, she knocked her over.
