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

Spayed or Neutered,

Story

Hi, my name is Max, Male - neuteredSt. Bernard x Mastiff MixApprox. 1 year, 9 months oldI am hoping to find my forever home soon. I've been the longest resident here, having arrived in April 2025 as a transfer to reach a new audience of potential adopters. Despite my efforts to charm everyone with my friendly nature, I've been overlooked. I'm determined to find the perfect family who will appreciate my unique personality and quirks.When it comes to meeting new people, I am generally friendly but can be a bit cautious and selective. I thrive in the company of adult humans and enjoy their companionship. However, I must admit that I'm not a fan of children, so it's best for me to be in a home without little ones to ensure everyone's comfort and happiness.I have a few key motivators that bring out the best in me: toys, treats, people, and praise. I love a tasty snack, but moderation is key to keeping me healthy and happy. While I've mastered basic obedience, I still have a big puppy demeanor that sometimes shows in my leash skills. I'm known for creating my own symphony by flipping my dish around and pulling the stuffing out of plush toys-what can I say, I'm a musician at heart!I long to be the King of my castle. When it comes to other dogs, I am quite selective, but with time and proper introductions, I might slowly warm up to playdates. However, I would truly thrive in a home where I can be the solo pet, soaking up all the love and attention. I must confess, I'm not fond of furry felines, so a cat-free home is essential.If you're looking for a loyal, fun-loving companion who will fill your home with joy and laughter, I might just be the perfect match for you. Primary Color: White Secondary Color: Brindle Weight: 42 Age: 1yrs 9mths 2wks
