Story

Meet Gus Gus is an 8-year-old black Mastiff with a heart as big as his paws. Found as a stray in Ontario alongside his friend—possibly his daughter—Tavi, Gus has shown nothing but gentle, loving energy. While they would love to find a home together, they can be adopted separately if needed. Weighing in at approximately 115 lbs, Gus is a true gentle giant. He’s the sweetest big boy who lives for chew sticks, affection, and cozy snuggles. Gus would be perfectly happy spending his days as a couch potato, soaking up love and giving it right back. He is housetrained and has wonderful manners, making him an easy, loving companion for a calm home looking for a loyal best friend. ##2648733##

Details

Good with kids, Good with dogs, Good with cats, House-trained, Spayed or Neutered, Shots are up-to-date,

Story

Nala is a beautiful 4-year-old large breed mix (Cane Corso type), approximately 120 lbs, with a loyal and affectionate personality. She is fully house-trained and understands basic commands such as “sit” and “stay,” responding to both Spanish and English. She has a gentle and patient temperament, especially with children. Our two-year-old daughter has grown up with her, and Nala has always been loving and careful around little ones. She is friendly with other dogs and enjoys playful interactions. Despite her size, she has a soft, playful side — she loves carrying her stuffed toys and being close to her people. She is naturally protective but not overly reactive, barking only when appropriate. She is spayed and up to date on all vaccinations. Due to changes in our family circumstances, we are seeking a stable, loving home where she can receive consistent attention, companionship, and care. $150 rehoming fee applies to ensure serious inquiries.
