Story
Ollie is an 18month old Bull Mastiff who was surrendered to us recently. He is such a quiet gentle boy. Ollie came to us with one eye but that does not stop him from enjoying life, he really wants to be in a loving home. Ollie used to live with a bulldog and he seems to be fine when other dogs walk past his kennel....and the horses too! Ollie is best suited in a home with children 16+ not only due to his size but Ollie seems to have had some trauma with children and does not do well when they are around. He is such a sweet and gentle giant. Ollie is vaccinated, microchipped and is neutered. If interested, please send us an application https://form.jotform.com/201994848495070 or email- havenoftheheart1@gmail.com

Hello there! My name is Thor, Male - neuteredMastiff x American Bulldog MixApprox. 1 year, 6 months oldI'm a big lovable marshmallow in a BIG package. 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. I thrive best with slow and gentle introductions. Once I feel comfortable, I'm your classic wiggle bug, eager to make friends and soak up all the affection you have to offer.I haven't quite figured out which toys I like best yet, but I'm excited to explore and find my favourites with you! 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.

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: 38.005 Age: 1yrs 7mths 2wks
