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##

Story

I am a fun, loving boy who loves to play. My only fault is I do not realize my size. I think I am a lap dog. I am house trained, and good with most other dogs. I would prefer to meet potential companions before going to a new home. ##2427887##
