Story
True to his wonderful breed of a Newfoundland mix, Superman (aka Moose) is an affectionate, smart, and calm dog believed to be 6-7 years old. He's hoping to find a stable and loving home, where he can relax and serve as the devoted big teddy bear that he is, having had a complicated journey with conflicting narratives... Superman first arrived at Big Bones in 2024, actually, having made the trip from Texas to Colorado to start a new life. He was a sweet boy and soon adopted into what seemed to be a good situation. As far as we know, everything was going well for him since that time. In February 2026, Big Bones was contacted by a dog shelter in Denver that scanned his microchip linking him to our rescue. Before being dropped at the shelter by his previous adopters, Superman was good with dogs and kids. Lucky for him, he is back in a safe place, and is ready for a REAL forever home!!

Details
Good with kids, Not good with dogs, Not good with cats, Needs experienced adopter, House-trained, Shots are up-to-date,
Story
Sierra is a five-year-old ~110-pound Anatolian shepherd mix who came from a family in Montana that was unable to give her the care and attention she needs. She was kept outside too much, but we have been working with her since February, integrating her into our family, dog walks, belly rubs and brushing, etc. She's a working/herding/guard dog but is also a goofball and a very cuddly teddy bear who loves people and has done well around children. She does have protective/guarding tendencies that seem to have been exacerbated by her situation at her former home, and would do best in a house with a fenced yard and without other dogs or pets (strong crittering instinct). However, she has also made HUGE progress on her dog walks and hasn’t shown any reactivity to other dogs in weeks. Sierra loves being brushed, hanging out with her people, and belly rubs. She is a very sweet girl and would make a great companion for the right person!

Sebastian is the ultimate gentle giant in the making. He has not once had an accident in his crate, doesn’t rip apart blankets etc in crate. It’s not his fav but the only time he barks is when he has to go potty in the morning when we get up and he’s in kennel. He lovesssssss everyone. He does great with the other dog in the home Cat hates him but he is desperate for her to love him. He is very respectful of her space too. He is a great pup for kids. Possibly older as he is still learning not to be a puppy piranha House training is going amazing. He is on a steady routine and is getting so good at communicating when he has to go out. Maybe a few accidents at most in house so far?
