Story
Kodiak is the true definition of an adventure buddy! Do you enjoy hiking, running, biking, swimming or exploring? Kodiak is the perfect dog for you! In fact he is already and waiting at the door for you! He is an intelligent dog who is capable of learning extremely quickly. He already knows the commands sit, down, stay, come, and speak! Kodiak’s greatest strength is his loyalty; Up or down, good or bad, happy or sad it will be Kodiak and you against the world. What makes Kodiak special is that he has so much love to give. The exact reasons you are looking for a dog are the same reason Kodiak desperately wants his forever human. He will need a very active adult-only family to drain his energy in order to keep him happy. Kodiak is looking for an experienced and confident owner to continue working on his reactivity to dogs and new people. He will need a strong leader to slowly introduce him to new people using the methods he has been taught while at Dog Tales. Kodiak is not friendly with strangers, children or other animals. Therefore he will need to live in a house with a fully fenced backyard. Once he is comfortable with a person he will become very attached and a great listener. Kodiak is looking for his chance with someone special. Upon adoption, Dog Tales can provide training for Kodiak and you in order to set you up for success.

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.

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.
