To understand Sydney Sweeneys love for Tank, you first need to understand Sydney Sweeneys great-grandmother.
Her great-grandmother loved dogs so much that she owned eight.
One weekend, she brought a 17-year-old Sydney with her.

Sydney Sweeney’s dog, Tank, in her Los Angeles pool.
The teenager saw a female pitbull-mix puppyno more than four weeks oldin a cage.
Her stomach was an angry red mess of infected stitches.
She had been fixed at a really young agelike, two and a half, three weeks old.

Youre not supposed to do it that young, Sydney says.
The staff told her they werent sure if shed live.
Sydney was heartbroken, and also under lax supervision: Her great-grandmother told her to go for it.

So she adopted the dog, drove home to Los Angeles, and surprised her parents.
They immediately grounded her.
So thats exactly what she named her.

Sweeney first adopted Tank as a puppy back when she was in high school. Sometimes, she’d even bring her to class.
From that moment on, Tank went with Sydney everywhere.

The moment we call action, she stops moving and doesnt make a sound.
Then you call cut and then she gets up.
Shed hang out in Sydneys trailer or run around theEuphoriaback lot with Jacob Elordis golden retriever, Layla.

Tank accompanies Sweeney on everything from hikes to the sets of her movies.
Sometimes shed even watch her human film a scene.

Was Tank able to understand her owner had become famous?
At first, Sweeney says she doesnt think so.
But then she pauses.
Maybe she knows it because she got a backyard?
Since they lived in an apartment, she explains, Tank didnt have one for awhile.
Five years ago, the actor bought her own first home in Los Angeles.
Tank took off running the moment she hit the grass.
Tank, I did this for you!
This is your backyard!
That was the most fulfilling moment of my life, she says.
