Story
You can fill out an adoption application online on our official website.Meet Tinsel  Part of our Emergency Christmas Crew, Tinsel is a Mastiff x Rottweiler mix (with maybe a little Beagle spice) born September 4, 2025. This sweet girl has proven to be incredibly social with people, dogs, and cats. She’s done wonderfully with cats, kids, adults, and dogs of all sizes and ages—a confident, happy puppy who truly loves being part of the action. Tinsel is crate trained, working on leash skills and house manners, and doing very well for her age with only the occasional puppy accident. She enjoys adventures and exercise but is just as happy curling up as a snuggle bug. She’s very food motivated and exceptionally bright, often picking up commands and training quickly, making her a fantastic candidate for continued learning and formal training. Tinsel does experience car/motion sickness, so her adopters will need to be patient and prepared to help manage this as she grows (many puppies outgrow it with time and positive experiences). As a large-breed puppy, Tinsel is expected to grow into a big girl. Her future family will need to be committed to ongoing training and continued socialization to help her develop into a well-mannered, confident adult dog. If you’re looking for a smart, social, loving pup who would thrive with a canine companion, Tinsel may be the perfect addition to your family  For more on her backstory: 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.February 14, 2026, 6:01 pm

You'll find that my heart is just as large as my frame, and I'm ready to share all the love I have with my forever family.When it comes to people, I'm friendly but can be a little nervous, especially around sudden movements.

What really gets my tail wagging is praise, treats, and people. I'm highly motivated by love and snacks, which will make training and bonding with me a delightful experience.I'm still working on my basic training, which means we can learn together. With your guidance and a few tasty treats, I'm sure to pick up on commands and become the well-mannered companion you're looking for.So, if you're looking for a gentle giant who will fill your home with love and laughter, I'm your guy.
