Story
Meet Mr. Big – A Little Dog with a Big Personality!Mr. Big may be small in size, but he’s overflowing with character! This senior mix breed is on the lookout for a calm yet active home where he can be the centre of attention. He’s a bit of a picky guy and knows exactly what he wants—a single individual to call his own, with no children or other pets.While Mr. Big enjoys socializing with dogs outside the home, he’s not a fan of sharing his space or belongings. He has resource guarding tendencies with toys, food, furniture, and his favourite people. Despite having minimal teeth, he’s still got plenty of spunk and can be touch-sensitive with new people, so an adopter with dog experience is a must.Mr. Big will thrive with clear boundaries and structured management. He’ll need an owner committed to consistent training and teaching him more release cues to help with his guarding behaviours. Until then, he’ll require careful supervision around valued items and firm but fair guidance to build trust and prevent conflicts.Once he’s comfortable, Mr. Big is a total sweetheart who loves treats, snuggles, and long walks, but he’ll be happiest in a home where he doesn’t have to share the spotlight. If you’re an experienced dog owner ready to give Mr. Big the one-on-one love, structure, and support he needs, he’ll reward you with loyalty and plenty of cuddles. IN SHELTER NOTES AND IDEAL HOME:SIZE:18 poundsHOME TYPE:House or Townhouse - No Apartments due to barrier reactivity (Barking through door). Separate exist dwellings are fine!CHILDREN:No - Due to resource guarding.CATS AND SMALL ANIMALS:No - strong prey driveOTHER DOGS:No - Not in home.

This is a select protein based diet that comes from a vet that helps with his food sensitivities. Some food causes Mr. Big to be itchy but this medicated diet and regular soothing baths have helped him greatly. He will need to continue on this diet until your vet advises otherwise.ACTIVITY/ENERGY LEVEL:Mod - High; will need daily exercise, enrichment and mental stimulation but enjoys some daily down time as well.HUMAN COMPATIBILITY:First time dog owner, No - Due to his behaviour needing lots of management; he needs an adopter that is willing to a

Story
Available to Foster or Foster to Adopt Located in Paris, Ontario Born December 9th 2024 Adoption fee $700 Hi, I’m Beth, a gorgeous Mastiff mix pup with a heart as big as my paws! My siblings and I were born outside, braving the freezing cold, until we were lucky enough to find a warm place in rescue. Not long after I left my siblings for my very own foster home, I ended up in emergency surgery to treat two inguinal hernias. I was in critical condition, and they weren’t sure I’d make it through, but I wasn’t ready to give up! I fought through it and have been thriving in my foster home ever since. Despite every challenge I’ve faced, I’ve kept fighting, and now I’m ready to find the forever family I fought so hard for! I’m a total cuddle bug—my favorite place to nap is curled up in your lap. With my princess personality, I love being wrapped up in a cozy blanket. When I’m not snoozing, you’ll find me chasing toys, working on treat puzzles, or chewing on peanut butter Kongs. I’m currently living with three other dogs, and we get along great! I haven’t been around cats yet, but I’m pretty sure I’d be just fine with them. Potty training is still a work in progress, so I’ll need a family willing to help me with that. I do great in my crate and sleep soundly through the night, only crying if I need to go potty. I’m the perfect mix of playful companion and snuggly lap dog, and I’m looking for a family who’ll love me as much as I’ll love them. Together, we’ll make all the battles worth it! I am up to date on my vaccines, microchipped and will be spayed prior to moving to my furever home. If you think your home would be a good fit for a spunky girl like me, please fill out the application below. https://form.jotform.com/221626931360250

Story
Available to foster or adopt 3 years old Fostered in London, Ontario Well hey there!! I’m Noelle! And I’m ready to steal your heart! I came from a local First Nations community, where I was living outside with my pups. But luckily, we were all brought into care on December 14, 2024, and now I’m enjoying the good life indoors, all cozy and comfy. My pups don’t need me anymore, and now it’s my turn for some extra love and attention! Unfortunately, I tested positive for both heartworm and Lyme disease, so I am looking for a foster or adoptive home to let me relax while I go through treatment. My medical care is paid for by the rescue. I’m a total sweetheart: calm, loving, and always up for snuggling with my humans. I’m housebroken and great with kids. I’m eager to learn, and I’m pretty proud of my leash skills (they’re a work in progress, but I’m catching on!). I’ll always be near you, hoping for some pets—and maybe a snack or two (I’m very generous that way). I am still learning the ropes when it comes to leash skills but with patience and training, I’m making progress and looking forward to continued improvement! I am reactive to other dogs , so a home with no other pets is a must for me. I need a family who is willing to continue working with me and maybe, hopefully one day I will learn to love some doggy friends! I have been microchipped, am up to date on my vaccines and will be spayed in the near future. If you think your home could be a good fit for me, please apply below! https://form.jotform.com/221626931360250
