I'm ready for my new family!

Hi! My Name Is Millie

I'm Available

Meet Millie — a 7-month-old terrier mix bursting with personality, brains, and just the right amount of mischief. This Jack Russell/Rat Terrier blend is all things playful, curious, and delightfully energetic. She’s the kind of pup who will keep you laughing, keep you moving, and keep your heart very full.

Millie is incredibly smart and already knows sit, down, off, come, and leave it — and she’s eager to keep learning. She thrives on activity, so her ideal home will include multiple daily walks, playtime, and continued training to help her grow into the amazing adult dog she’s meant to be. She’s house-trained, sleeps soundly through the night in her crate, and happily runs in at mealtime (especially if there are tasty treats involved — dried liver, sweet potato chews, or a frozen Kong are her love language!).

This sweet girl adores people — men and women alike — and greets life with enthusiasm (and sometimes a bouncy puppy hello). She enjoys kids 10+ who can match her energy and respect her space. Millie is also cat-friendly, making her a great fit for a feline-inclusive home.

Millie is still working through a few puppy challenges. She can be reactive with other dogs and will need a patient, committed adopter to support her training and help build her confidence. She prefers to enjoy her meals and special items without canine competition, but she has no guarding concerns with people. She’s also learning leash manners and how to stay focused when exciting distractions (like skateboards or strangers in hats!) appear. Millie is currently making progress with separation anxiety in her foster home but would prefer a home where her family is home often. She’s happy to relax in her crate when her humans are nearby, but she’ll need a dedicated home that can continue working on crate training and helping her build confidence to feel safe and secure when left alone.

At home, Millie loves to check in with her people, enjoys a good snuggle before starting the day, and will happily curl up after a full day of adventures. She may bark at unfamiliar noises or visitors, but she’s not excessive — just a young dog learning the world.

Millie isn’t looking for perfect — she’s looking for someone willing to grow with her. With guidance, structure, and lots of love, she will blossom into an incredible, loyal companion.

If you’re ready for a clever, affectionate, high-energy best friend who will keep you on your toes (and smiling), Millie just might be your girl.
