Story
Meet Sloane - A Gentle Giant in the Making! Sloane is a sweet, loving Mastiff mix puppy with a heart full of potential and a personality that becomes more endearing every day. At just 5 months old and weighing approximately 43 pounds, this gentle girl is a beautiful example of how much love, patience, and positive experiences can help a shy puppy blossom. Sloane is a little reserved when meeting new people and may need some time to feel comfortable in unfamiliar surroundings. Once she begins to feel safe, her sweet personality shines through. She is a loving girl who enjoys being close to her people, and when she settles down in the house, she may choose to lie right on your feet just to be near you. Of course, she is still a puppy, and the occasional zoomie is always a possibility! Her larger size makes her puppy antics especially adorable. While working on her leash walking, Sloane has shown her playful, silly side by flopping onto her back and rolling around like a big puppy who hasn't quite figured out how to coordinate all those legs yet. These moments are a wonderful reminder that beneath her size is a young dog discovering the world and learning to enjoy being a puppy. Sloane is a bright girl who is picking up her training quickly. She is learning commands such as sit and stay, and she is making excellent progress with her house training. With regular trips outside and attention to her cues, she is very close to having this important skill mastered. She is also becoming comfortable with her crate and will happily self-crate during the day. At night, however, she would much rather be close to her people. Her affectionate nature makes her a wonderful candidate for a family who enjoys having their dog nearby and can continue helping her build confidence at her own pace. Sloane is good with women, men, children, and other dogs. She currently lives with seven cats and has quickly learned to respect their boundaries, which is a lovely reflection of her ability to learn and adapt. She does not bark excessively, is not food aggressive, and rides well in the car. She is still working on her leash skills, but she is not reactive toward people or other dogs. As a high-energy puppy, Sloane will thrive with a family ready to provide daily exercise, training, playtime, and plenty of positive experiences. A securely fenced yard is important for her, and a home with another friendly, well-socialized dog is preferred, as she is accustomed to canine companionship. Apartment living would not be the right fit for her. Sloane is looking for a loving family who understands that confidence takes time and that the best relationships are built through patience, trust, and consistency. In return, she has every opportunity to grow into a loyal, affectionate, and wonderful companion. If you have room in your heart and home for a big, beautiful puppy with a gentle soul, a playful spirit, and so much potential, Sloane would love the chance to meet you! * Good with women: Yes * Good with men: Yes * Good with children: Yes * Good with other dogs: Yes * Good with cats: Yes, currently living with seven cats and learning to respect their boundaries * House trained: Almost there; regular outdoor breaks and attention to cues are helping * Crate trained: Progressing well; self-crates during the day but prefers to sleep near her people * Leash walking: Learning * Leash reactive: No * Rides well in the car: Yes * Barker: No * Food aggressive: No * Destructive: Typical puppy behaviour, though she does not appear to be a particularly strong chewer * Needs a yard: Yes * Another dog preferred: Yes * Apartment living: Not recommended As with all newly adopted or fostered dogs, Sloane should be considered a flight risk while she adjusts to her new home. A secure environment and careful management during her transition will help keep her safe.

Story
**Meet Chippy - A Gentle Giant with a Playful Spirit!** Chippy is a handsome Shepherd/Mastiff mix with the perfect combination of playful energy and a calm, loving nature. At three years old, he's a wonderful companion who enjoys a good game just as much as he enjoys relaxing with his family. With his sweet personality, loyal heart, and easy going temperament, Chippy is ready to find the forever home he's always deserved. Chippy and his brother, Brutus, have been cherished members of their family since they were puppies. Sadly, due to circumstances completely beyond their family's control, they must now find new homes after a community member repeatedly threatened the dogs. Wanting only to keep them safe, their family made the difficult decision to surrender them so they could have the opportunity to live happy, secure lives with loving families. Chippy is a friendly, social boy who truly loves people. He's wonderful with men, women, children, other dogs, and even cats, making him an excellent fit for many different types of families. His affectionate nature and gentle disposition mean he quickly becomes everyone's friend, and he loves being included in whatever his people are doing. If there's one thing Chippy is passionate about, it's **playtime!** He absolutely loves chasing tennis balls, retrieving sticks, and proudly carrying his favourite treasures around the yard. Whether it's a game of fetch, exploring outdoors, or "helping" with the woodpile, Chippy approaches life with enthusiasm and a happy wagging tail. His playful side is balanced by his calm demeanor, making him just as content relaxing with his family after a day of fun. Having spent his life in a rural environment, Chippy would thrive in a home with a securely fenced yard where he has room to run, play, and enjoy the outdoors. A rural property or quiet suburban neighbourhood would suit him best as he settles into his new home. Chippy is house trained, well-mannered indoors, and not destructive or barky. He enjoys being close to his family and is happiest when he's included in everyday life. While he's still learning to walk on leash, he's eager to continue building his confidence with positive reinforcement, patience, and gentle guidance. Chippy also enjoys the companionship of other dogs and would love a home with a friendly canine sibling. Having another dog around would provide companionship, playtime, and help make his transition into a new home even smoother. Chippy is the kind of dog who will happily join you for a game in the yard, a walk through the countryside, or a quiet evening at home. His gentle heart, playful personality, and unwavering loyalty make him a truly special companion. **If you're looking for a loving best friend who will bring joy, laughter, and unconditional love into your life, Chippy is ready to meet you. Open your heart to this wonderful boy, and he'll reward you with a lifetime of devotion.** Good with men: YesGood with women: YesGood with kids: YesGood with dogs: YesGood with cats: YesHousetrained: YesCrate trained: NoCan be handled/touched: YesEnergy level: MediumFlight risk: All newly adopted or fostered dogs are a flight riskFood aggressive: NoBarker: NoWalks on leash: No, needs trainingLeash reactive to people or dogs: NoRides well in car: UnknownDestructive: NoNeeds a home with a yard: YesNeeds a home with another dog: YesCan live in an apartment: No Please visit our website niagaradogrescue.com to learn more about this amazing pet and to see other available dogs.
