Story
Meet Spotty Dotty! Spotty Dotty's story began with heartbreak, but her future is filled with hope. Found abandoned in Northern Manitoba, Spotty Dotty spent weeks waiting faithfully for her owners to return. Sadly, no one ever came back for her. By the time caring neighbours found her, she was severely underweight and starving, yet she never lost her gentle spirit. Since arriving in foster care, Spotty Dotty has flourished. She has settled beautifully into her foster home, adores her foster dog siblings, and has shown everyone what a truly special dog she is. Despite everything she has endured, she remains incredibly affectionate, loving, and trusting. Spotty Dotty is a cuddle enthusiast who loves being close to her people. She has a calm and gentle demeanor that is remarkable for a dog her age and makes her a wonderful companion for a family looking for a loyal best friend. Her sweet nature, kind heart, and quiet resilience shine through in everything she does. Having experienced more hardship than any dog should, Spotty Dotty deserves a family who will cherish her and show her the love she has always deserved. In return, she will reward you with unwavering loyalty, endless affection, and a lifetime of companionship. You won't regret opening your heart to Spotty Dotty. She is truly a treasure-a gentle, loving soul who is ready to spend the rest of her life knowing she is safe, wanted, and loved.

Good with kids, Not good with dogs, Good with cats, Needs experienced adopter, House-trained, Spayed or Neutered, Shots are up-to-date,
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.

A full-body lean or her head resting gently in your lap.BIO: - St. Bernard/Mastiff Mix, 5.5 Years, Female (spayed)- Extra-large (95 lb) High-energy - Daisy was found as a stray and was at an over-crowded municipal shelter before coming to EHS- Daisy is house-trained, microchipped and has her core vaccinationsABOUT DAISY- Daisy`s 3 favourite things are sniffing-walks, enjoying a treat filled kong and getting pats from you - Daisy walks mostly loose-leash, but can pull when she sees a small critter and she can be strong. She shows interest in other dogs she sees on a walk but is not reactive, only letting out the occasional bark or just stopping to observe- A friendly and social girl she loves hanging with people and greets everyone she meets with happy tail wagsDAISY`S IDEAL HOME:- Daisy would thrive with a family that can provide regular walks, playtime, and plenty of affection- We are recommending Daisy for an adult-only home with dog-experienced owners (preferably experienced with Bully or Mastiff breeds)- Daisy needs to have what she is communicating listened to and understood- She would do well in a quieter area, she is not well-suited for a busy downtown area, she can be sound sensitive to loud traffic or noises- Daisy can sometimes be vocal, she would do better in a non-shared wall situation- We are not recommending her for a home with other petsDaisy is proof that the biggest dogs often have the most sensitive hearts If you have any questions about Daisy, contact her Adoption Coordinator at: dog.adoption.coordinator3@etobicokehumanesociety.com
