Story
Meet Huxley – Your Next Adventure Buddy!If you’re looking for a fun-loving, high-energy companion who’s always up for action, Huxley might just be your perfect match! This handsome boy has a wiggly bum, a big smile, and a zest for life that’s absolutely contagious.Huxley loves to run, chase, and play—especially if toys are involved! Whether it’s a game of fetch, a long hike, or just zooming around the yard, he’s happiest when he’s moving. He’s strong and athletic, so he’ll do best with someone who enjoys being active and can match his enthusiasm.Huxley does have a bit of a prey drive, so he’d prefer a home without small animals, and he can be reactive around other male dogs—he’s still learning his manners there! But with structure, patience, and positive training, he’s eager to learn and please his people.After all the excitement, Huxley loves to relax with his humans, soaking up affection and giving plenty of tail wags in return.If you’re ready for a loyal, goofy, and spirited adventure partner, Huxley can’t wait to meet you!IN-SHELTER NOTES & IDEAL HOMESIZE:68 lbs.HOME TYPE:House.

He’s goofy, playful, and discovering the world with that classic puppy enthusiasm. He loves toys, enjoys exploring, and is learning all the basics — from polite manners to the fun of zoomies. His confidence grows every day, and his gentle personality shines through in every tail wag.This sweet boy is looking for a patient, loving home that will continue helping him build on everything he’s learned so far. In return, Ruin will offer endless cuddles, joyful energy, and the truly special reward of seeing a once-struggling pup become the dog he was always meant to be.If you’re searching for a resilient, affectionate companion, Ruin is ready to join your family.IN-SHELTER NOTES & IDEAL HOMESIZE:45 lbs. and still growing!HOME TYPE:Any!CHILDREN:Yes - Potentially compatible with childrenCATS & SMALL ANIMALS:Yes- Cats potentially compatible with slow proper introduction.OTHER DOGS:Yes- Dogs potentially compatible.ACTIVITY/ENERGY LEVEL:High; will need a lot of daily exercise, enrichment and mental stimulation.HUMAN COMPATIBILTY:First time dog owner possible.TRAINING REQUIREMENTS/NEEDS:At least three in-person training sessions to work on socialization, basic training, and manners.**Please remember that animals are coming back from foster care to the centres for their meet and greets.

Story
Brutus is a big-hearted, big-bodied boy looking for a family to call his own! This handsome large breed mix has a playful, active side — he loves to run, play, and get the zoomies — but what he really loves most is you. Once he feels safe, Brutus turns into a total cuddle bug who melts right into your arms.Having come from the streets, Brutus can be a little nervous in new environments, but with patience and gentle encouragement, his affectionate personality quickly shines through. Because he’s still learning what it means to live in a home, Brutus can be a bit of a shoe thief or get into mischief if left unsupervised — a crate or puppy-proofed space will help set him up for success. He’s looking for an adopter who understands or is willing to learn about working shepherd breeds and their need for exercise, structure, and mental stimulation.IN-SHELTER NOTES & IDEAL HOMESIZE:77 lbs.HOME TYPE:House or Townhouse with no shared entrances (Private exit homes)CHILDREN:Yes- Older dog savvy children.CATS & SMALL ANIMALS:No - has shown some prey drive behaviours.OTHER DOGS:Yes - Potentially compatible with other dogs.

TRAINING REQUIREMENTS/NEEDS:At least 2 in-person training sessions to work on socialization, basic training, and desensitizing to new sounds/environments.
