Story
Hello! My name is London!I`m a fun and loving girl! I am snuggly and affectionate. I love treats and toys, which makes training a blast! I sometimes get excited and like to grab sleeves with my mouth. I thought that was fun but apparently humans don`t enjoy it as much as I do. No worries though, I`m super smart and doing well with training - I`m learning about other fun things to do instead. If you love cuddling, playing and snoring, I am definitely the girl for you!MY IDEAL HOME INVOLVES…CHILDREN: Teenagers may be ok. No young kids given my mouthing can sometimes be hard.OTHER DOGS: I don`t seem to enjoy the company of other dogs and I`m looking to be the only dog.CATS: Potentially, with cat experienced and confident around dogs.FIRST-TIME DOG OWNERS: I would do best with someone who has dog experience.FENCED-IN YARD: Required.HOUSING ENVIRONMENT: Any with yard.SOMEONE HOME MOST OF THE DAY: Not necessarily.SOME OTHER THINGS TO KNOW ABOUT ME…ACTIVITY LEVEL: Medium.HOUSE-TRAINED: Yes.If you think I could be a good match for your home, click the “Adopt Me” button to apply!FOSTER ME!

Story
Oscar is a handsome three-year-old Mastiff cross with a big body and an even bigger heart. This lovable giant has quickly become a staff favorite thanks to his sweet nature, eagerness to please, and calm presence in his kennel. Despite his size, Oscar is a gentle soul who enjoys spending time with people and thrives on connection and positive interaction. Oscar is a medium-energy dog with short bursts of playful enthusiasm —especially when toys are involved! He absolutely loves playtime and is easy to redirect, making him a great candidate for continued training. He’s a smart boy who responds well to guidance and is already showing that he has the potential to become a well-mannered, balanced companion with the right structure in place. Due to his size, strength, and current lack of manners, Oscar is looking for a home with large-breed experience and a confident, physically capable handler. He doesn’t quite realize how big he is, so ongoing positive reinforcement training will be key to helping him learn boundaries and polite behaviors. Enrolling him in training classes is strongly recommended and will set him up for success. Oscar does show some reactivity toward other dogs, particularly males that react to him. However, his behavior is manageable with the right approach. He would benefit from a home committed to maintaining safe distances, using high-value rewards to build positive associations, and consistently working on obedience while keeping him under threshold. With patience, structure, and continued guidance, Oscar has great potential to make progress in this area. Because of his size and strength, a home without young children is recommended. Oscar will also need daily physical exercise and mental enrichment to keep him happy and fulfilled. The good news is that he settles well in his kennel and may do very well with crate training in his future home. Oscar is a sweet, intelligent dog who is ready to thrive with the right match. With consistency, training, and lots of love, he has all the makings of a loyal, well-balanced companion. Please complete an adoption application: https://www.hamilton.ca/home-neighbourhood/animals-pets/adopt-or-foster-pet/adoptions Animal adoptions and viewing are by appointment only. This allows our Adoption Staff to spend quality time with each potential home to ensure the most successful matches are made between the animals and their new families. *Please note: we only adopt within Ontario

Story
Ranger is vocal and loves to tell you about his day and then tell you again! He loves to be pet and looks at a gate as a challenge, not a barrier. He can be stubborn and defiant, so a strong Alpha owner is needed or he will take control. He is a powerful puller on leash, so a harness is best. He likes car rides and is crate trained. He is looking for a forever home that has some experience with the food motivated lab and stubborn mastiff. Due to his size and strength, older children are best. He has a great smile, and will show all his teeth when he is happy or nervous. He is up to date with his vaccines, flea and tick treated, microchipped, Heartworm negative and is neutered. His adoption fee is $500. You must be 21 years old to adopt and provide vet and personal references. An application to adopt him can be found on our website www.oxfordcountyanimalrescue.com. Click on Adopt, then Dogs for Adoption and scroll to the bottom of the page. All applications are reviewed, and if we feel you might be a good fit for him, you will be contacted to arrange a home visit as well as for permission to speak with your vet. Repeated phone calls and emails with not advance your application. We are a volunteer, foster based rescue and there is no opportunity to meet him before an application has been approved. We thankyou for respecting these guidelines.

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.

Story
Meet Honey. This gentle senior girl was found wandering the streets, alone and in pain. Her joints ached, her hips were stiff, and her body told the story of being left outside for far too long. But her story is changing — thanks to the love and expertise of her foster mom, a vet tech who’s made it her mission to help Honey heal. And she is healing. Honey is now on a regimen that helps her thrive: daily Metacam, Cartrophen injections, and joint supplements. Like many seniors, she’ll need to stay on this care plan — but it’s a small price to pay for the comfort and love she so deeply deserves. What’s sweeter than Honey? Absolutely nothing. We all hope to grow old with dignity and peace. But imagine finally reaching your golden years, only to be discarded like you no longer mattered. That’s what happened to Honey. Did she do anything wrong? Never. She was simply born kind, gentle, and full of love — and that’s still exactly who she is. She sleeps next to her foster sister’s crib at night, quietly keeping watch. She wears silly hats and dish towel “blankets” because it makes the baby laugh. She’s even stolen the heart of her foster brother, who now lays beside her in quiet companionship. She brings peace and warmth to every room she enters. She’s perfect. Now it’s time for her forever. Honey deserves a family who will cherish her through her senior years. Someone who sees the beauty in her graying muzzle, who understands her past, and who is ready to give her the soft landing she never had. If your home — and your heart — has room for a little sweetness, Honey is ready. Apply today and let her golden years shine.
