Story

Thank you for your interest in Hubert. He is such a fun loving, energetic, happy, barky boy. He loves people and dogs and life. Some of it he loves a little too much. Well, not too much for him but too much for other dogs. But he is really just a softee who wants to run and play and be chased. Hubert hasn't had the best start in life. He was sold to an elderly owner who wasn't able to manage a happy, energetic dog so Hubert landed in a day care/boarding facility. His owner wasn't able to take him back and the really sad things started happening. He was sold, returned, sold, returned and finally someone took him to the vet. Hubert was really matted and was finally groomed. It was then discovered that he had a terrible ear infection and an infected toe! Once again people had failed him. Off to the vet he went and as soon as he received treatment he felt so much better and his happy came out! He went to live with another family and they really loved him but underestimated how much energy is required when you have a dog like Hubert so SPIN was called. Hubert is just the kind of dog we love! Running, bouncing, barking, playing, snuggling, hugging, what could be better?

Story

Jean-Pierre (JP) is a striking three-year-old Standard Poodle who has made remarkable progress since being found abandoned in Quebec. When he first arrived at the shelter, he was frightened, in pain from an untreated ear infection, and unsure of people. With care, patience, and medical treatment, he started to heal — both physically and emotionally — and showed the sweet, loyal nature that defines him today.

Story

BOWMANVILLE, ON - Thank you for your interest in Oakley. In early 2025 we received a call about a 9 year old standard poodle who urgently needed help. He was living in a puppy mill and was being used as a stud dog. The mill owner was done with him and wanted him out. Afterall, if the dog isn't making the mill any money, then they aren't worth feeding. Oakley was being freed! Our volunteers dropped everything, hit the road and brought this boy to safety. He didn't have a name and his coat was so overgrown and matted that it came off in one piece. He had sores hidden beneath the hair, infections in both his eyes and ears and a mouth that needed attention. And yet-he was still wagging his tail. What a boy! Life has been better since leaving the mill, but it hasn't been perfect. Oakley has struggled. He's trying to learn all about living in the big, exciting world, but it's scary and he didn't learn the skills early in life when it's easy. Being a senior and trying to learn all new things is tough! Add to it that he's a dog and is trying to live in a human world and it's even tougher! But we LOVE this boy. Seriously. Those of us who have been lucky enough to spend time with him know he is trying his best to live in our world.

Story

Meet Sansa 🐾 Sansa is a 4-month-old, 11 lb spaniel mix with a heart as soft as her beautiful coat. With her mom weighing under 30 lbs, we expect Sansa to stay on the smaller side as she grows. This sweet girl is the perfect mix of gentle and playful. She absolutely adores children, loves going for walks, and is happiest when she’s outside bouncing around and exploring the world. When playtime is over, Sansa is just as content to curl up beside you for some cozy snuggles. Sansa came to us from Mexico, where her mom was found caring for a litter of puppies. Now safe and thriving, she’s being fostered in Mississauga and is ready to find her forever family. Like all puppies, Sansa will need a family committed to training, patience, and consistency to help her grow into the amazing dog she’s meant to be. With her loving nature and beautiful personality, she is sure to make a wonderful addition to the right home. If you think Sansa might be the perfect fit for your family, we encourage you to apply today ••••••••• As my foster family gets to know me my profile can change and will be updated accordingly. Check back often for details! An application for me can be found at www.justpaws.ca. Just Paws is located in the Greater Toronto Area of Ontario, Canada. We do not adopt out of province or country. Please note that although many of our dogs get along with children, we are not able to adopt to any household with kids under the age of 8 years old. This is a stipulation of our insurance and is not a reflection on suitability of the potential adopter.

Story

Milly is a 5-year-old Beagle/Foxhound mix with a heart of gold and a personality that lights up every room. At around 50 pounds, this medium-sized girl is the perfect balance of affectionate cuddle bug and playful goofball. Personality Milly is truly everyone's best friend. She's gentle, devoted, clever, and endlessly sweet - a social butterfly who thrives on being around her people. Whether she's making you laugh with her silly antics or resting her head in your lap, Milly is happiest by your side. She's curious and loves to explore, but connection and companionship are what matter most to her. Training & Manners Milly is house-trained with excellent indoor manners. She has never needed a crate and is non-destructive in the home. She knows sit, stay, come, down, shake a paw, spin, touch, and crawl. She's intelligent and eager to engage, making continued training both easy and enjoyable. Energy & Ideal Home With a medium-to-high energy level, Milly would thrive in an active home that enjoys long walks, hikes, and outdoor adventures. A large, securely fenced yard would be ideal. She adores children and would make a loving family companion. However, she has a high prey drive and cannot live with cats. She also shows leash reactivity toward other dogs and would do best as the only pet, where she can soak up all the love and attention. Why Milly? Milly is a beautiful blend of playful and gentle, active and affectionate. She'll be your hiking partner, road trip companion, and loyal couch snuggler all in one. In the right home, she will blossom into an incredibly devoted best friend. Favorite This Pet Search More Pets
