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
Bentley is a sweet, gentle pup with a calm nature and so much potential. Rescued alongside his two brothers after being found wandering a remote highway in northern Manitoba, he is now searching for a patient, loving family to help him continue building confidence. While shy when meeting new people, Bentley is making steady progress and would benefit from having a friendly, well-balanced dog companion to show him the ropes. He is wonderful with other dogs, fantastic with cats, and is doing well learning to walk on a leash. Bentley being the largest of the brothers can be a bit pushy around food with them so continued management and guidance around mealtimes will be important, especially in a multi-dog home. Like any young pup, he is still working on his crate and house-training skills, but he is eager to learn and has shown nothing but a sweet, gentle temperament. Could Bentley be the perfect addition to your family?

Story
Are you looking for the one that melts your heart and your feet warm. Look no further than Mister Parker. How can you resist that face with his slightly crossed eye...he is imperfectly perfect! Mister Parker is currently is in a foster home with four other dogs and a cat so having some fur buddies in the home would make him more comfortable. He is a bit of a couch potato who also likes to weigh down your bed blankets. He is the best at couch naps because most times he is snoring with his eyes open. He walks well on a leash, navigates stairs without issues and is crated at times and just settles in and curls up. Mister Parker would do best in a home with older children as he doesn't see well and has some vision impairment. Because of this, making noise before entering rooms or approaching him is important so as not to startle him. Mister Parker likes to feel safe and secure so a calmer home is preferred. Hearing words of encouragement make him relax and enjoy life to the fullest. He definitely loves being outside and dinner time! Good with adults: Yes Good with Kids: Yes, older preferred due to vision impairment Good with dogs: Yes Good with cats: Yes House trained: Yes, once he understands where to go Crate trained: Yes Energy level: Low Can be handled/touched: Yes Flight risk: No; however, all dogs should be considered flight risks in new environments Food aggressive: No Walks on leash: Yes Leash reactive to people or dogs: No Rides well in car: Yes Destructive: No Needs a yard: Yes Needs another dog: No, but preferred due to vision impairment Can live in an apartment: No Please visit our website niagaradogrescue.com to learn more about this amazing pet and to see other available dogs.

Good with kids, House-trained, Spayed or Neutered,
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, 12:37 am
