Story
Meet Stewie, a lovable 4-year-old Mastiff mix looking for his forever home! Weighing in at 100 pounds, Stewie is a gentle giant whose biggest desires are cuddles and food. His past has left him a little overzealous when it comes to treats, so homes with small children might not be the best fit for him. Stewie is incredibly loyal and sweet, always ready to protect and love his family. He gets along well with other dogs, but due to his size and energetic play style, smaller dogs might not be the best playmates for him. Unfortunately, Stewie is not suited for homes with cats. This big-hearted boy had a rough start in life, having been starved before coming to his current foster home. Despite this, he’s shown an unwavering capacity for love and loyalty. Stewie is waiting for a family that can give him the care, attention, and endless cuddles he deserves. Please consider giving Stewie a chance to be your loyal companion! If interested please go to our website and fill out an application. You can find our application under the adoptable dogs icon. Thank you for choosing Ozzie and Friends Rescue. We can’t wait to connect you with your new fur-ever friend.  https://www.ozzieandfriendsrescue.org/   Ozzie and Friends Rescue makes arrangements for all dogs adopted to be transported all across the Western United States, Canada and Midwest.   November 6, 2024, 2:40 pm

Story
Stark is a very well behaved dog with a perfect temperament for children and adults. He has been leash, potty, and house trained. He is a very spoiled dog so he doesn’t quite realize his big size but loves snuggling and cuddling with blankets and movies. He is wonderful and fully trusted around our one year old baby, however due to the baby I have been unable to give him the attention he needs, as well as our baby's severe allergy to his dog hair which has not improved over time like we had hoped. He is such a good boy, and a wonderful addition to any family or new dog parents. He is very protective and cues on emotional distress and humorously when a diaper change is needed! He does not do well with other dogs unless slowly integrated into them one at a time.

Story
Meet Sabrina, a gentle 6-year-old Mastiff mix who’s in need of a special forever home. Sabrina is living with mast cell tumors (MCT) due to cancer and is currently on medication to keep her as comfortable as possible. She requires a loving home that is prepared to offer her hospice care and a peaceful environment. Sabrina can be shy with new people and may give a warning growl or snap if approached when she’s not ready. However, once she builds trust, she becomes deeply affectionate and very attached to her people. She gets along well with mellow dogs and will thrive in a calm household where she can feel safe and loved. If you have a compassionate heart and are ready to provide a supportive and caring home for a special dog like Sabrina, you’ll find a loyal and loving companion in her.
