Story
India Rottweiler/Boxer/Dogo Argentino mix (short coat) Large Adult Female   This gorgeous brindle gal is India a 4 year old, 100 pound mixed breed dog who will be up to date on her veterinary care and spayed prior to adoption.  Her current family is not able to provide her with the time or care she deserves.   India is housetrained and crate trained, although, a crate has not been used in the past year or so.  She is used to living in an apartment and is said to be quiet and comfortable being left alone while her family works full-time hours.  She may whine initially when left in a new environment.  She enjoys daily walks for exercise and to do her business.   India is a Mastiff mix, and as such, will most likely become very attached to her family members but may initially be a bit wary of new people and animals.  She warms up to women more quickly than men.  India is currently living with 2 toddlers and is good with them.   India has very limited experience with other dogs and has not lived with another dog.  She has a Husky friend she likes to interact with on leash.  She may react to other dogs when on leash walks who are as far away as on the other side of the street and needs a strong and confident owner to help her work through this behaviour using positive reinforcement based methods.  She has also never lived with a cat.   Her family is able to bathe and brush her and she has been professionally groomed.  Her regular groomer says she is good for grooms.  At the veterinarian, she is muzzled for invasive handling.  Muzzles can be a great tool to help dog handlers feel safe.   If you are looking for a loyal, large breed dog to snuggle with on the couch and believe you can provide India with the care she deserves, please fill out the Adoption Application on our website.     June 26, 2026, 11:34 pm

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.

Story
Easy-going & Affectionate HIs Foster Mom says he is ‘Delightful! A well-adjusted dog and happy to go along with whatever you’re doing.” An absolute cuddle-bug who just wants to be near his people. He will lean in against you for affection and paw at you for moreBIO: - Lab/Mastiff Mix, 2.5 years old, Male - Large (80 lb), Medium-energy- From Ginoogaming, transported by Northern Connection Dog Rescue- Remi is house-trained, microchipped and has his core vaccinations ABOUT REMI: - Good on a leash, he will show interest in other dogs with a wagging tail- Great in the car — hops right in, settles down and relaxes- There have been no signs of separation anxiety while in foster care- Overall he is chill and can show some shyness, especially at first, but he’ll open up fast and be putting his head on your lap for a nap before you know it- Very attentive and eager to connect — likely very trainable, you just need to find the right treats because he is not food-motivated and at dinner time he is more of a grazerREMI’S IDEAL HOME:- Besides being by your side, one of his favourite things is getting outside for a walk and some sniff time. His future family should be ready to enjoy daily walks with him.- Remi is a strong boy physically, but on walks he is mostly loose leash and he shows interest in meeting other dogs and may pull for that but is easily re-directed with a verbal reminder- A shared-wall situation may be okay, Remi is more of a gentle communicator than a barker- Remi has lived with cats before, if his potential adopter has a cat we will arrange a meet and greet- He has lived with children in the past and may be fine with children again. Older dog-savvy children that understand that slow and calm is best would be idealIf you’re looking for a loyal companion with a soft heart and calm presence, this sweet boy may be your perfect match!For more information about Remi visit our website at: https://etobicokehumanesociety.com/dog/adopt-remi/
