Story

Hi, my name is Max, Male - neuteredSt. Bernard x Mastiff MixApprox. 1 year, 6 months oldHello, future family! I'm the longest resident at the Georgina Animal Shelter, having arrived here in April 2025. My biggest wish this holiday season is to finally find my forever home.I'm a cheerful and lovable goofball who sometimes forgets just how big I am, but always in the most delightful way. I have a talent for striking a pose, especially when there's a treat involved. No matter the occasion, I'm always a sight to behold! I adore going for walks and love to bring my favourite stuffed toy along for the adventure. If you're up for some outdoor fun, just watch my tail wag with joy!While I am full of energy and love, I truly thrive in a quieter home environment without young children or other animals. Such a setting helps me relax and allows me to be the best companion I can be.If you're looking for a loyal friend who will bring endless joy to your life, I'm the perfect match for you. Let's make my holiday wish come true! Primary Color: White Secondary Color: Brindle Weight: 40.008 Age: 1yrs 8mths 3wks

Story

You can fill out an adoption application online on our official website.Meet Juniper Part of our Emergency Christmas Crew, Juniper is a Mastiff x Rottweiler mix (with maybe a little Beagle spice) born September 4, 2025. This sweet girl was fostered with her brother Dasher and has proven to be incredibly social with both people and dogs. Juniper truly thrives on companionship, and we believe she would do best in a home with other canine friends to play with and learn from. She has done wonderfully with cats, kids, adults, and dogs of all sizes and ages—a confident, happy puppy who loves being part of the action. Juniper is crate trained, working on leash and house manners, and doing very well for her age with only the occasional puppy accident. She loves adventures and exercise but is equally happy being a snuggle bug. She also appears to be the brightest of the litter, often being the first to pick up on commands and training, making her a fantastic candidate for continued learning and formal training. As a large-breed puppy, Juniper is expected to grow into a big girl, and her future family will need to be committed to ongoing formal training and continued socialization to help her grow into a well-mannered, confident adult dog. If you’re looking for a smart, social, loving pup who would thrive with a canine companion, Juniper may be the perfect addition to your family For more information on their backstory, check out their welcome post: https://www.facebook.com/share/p/17nfLJ7gtm/?mibextid=wwXIfr Apply to adopt and give this Christmas girl the forever home she deserves: https://www.hankshaven.ca/info/adoption #EmergencyChristmasCrew #PuppyForAdoption #AdoptOrShopResponsiblyVisit this organization's web site to see any additional information available about this pet.January 13, 2026, 6:36 pm

Story

You can fill out an adoption application online on our official website.Meet Navidad “Navi” Part of our Emergency Christmas Crew, Navi is a Mastiff x Rottweiler mix (with maybe a little Beagle flair) born September 4, 2025. This playful boy has proven to be incredibly social with people, cats, and dogs. He’s done wonderfully with cats, kids, adults, and dogs of all sizes and ages—a confident, happy puppy who loves being right in the middle of the action. Navi is crate trained, working on leash skills and house manners, and doing very well for his age with only the occasional puppy accident. He enjoys adventures and exercise but is just as content being a snuggle bug. He’s very food-driven and highly motivated, making him a fantastic candidate for training and learning new skills through positive reinforcement. If you’re looking for a smart, eager-to-please puppy and are ready to invest in his future, Navi may be the perfect fit. Navi does experience car/motion sickness, so his adopters will need to be patient and prepared to help manage this as he grows (many puppies outgrow it with time and positive experiences). As a large-breed puppy, Navi is expected to grow into a big boy. His future family should be committed to ongoing formal training and continued socialization to help him mature into a well-mannered, confident adult dog. If you’re looking for a playful, social, and loving pup, Navi could be the perfect addition to your family For more on his backstory: https://www.facebook.com/share/p/17nfLJ7gtm/?mibextid=wwXIfr Apply to adopt and give this Christmas boy the forever home he deserves: https://www.hankshaven.ca/info/adoption #EmergencyChristmasCrew #PuppyForAdoption #AdoptOrShopResponsiblyVisit this organization's web site to see any additional information available about this pet.January 14, 2026, 7:26 pm
