Story

Deuce is a tiger-striped Mastiff/Boxer mix who’s affectionate, playful, and great with kids. He enjoys spending time outdoors but is used to sleeping indoors. Though he has an alpha personality, he gets along well with smaller dogs. Deuce loves attention and quality time with his family. Unfortunately, our family is downsizing, and we’re looking for a loving home where he’ll be played with, taken on walks, and given the care he deserves. Deuce would make a wonderful addition to any family, offering both love and protection.

Story

I’ve had atlas since he was 6 weeks old. He’s almost a year and a half and weighs over 100 pounds. He’s 64% English mastiff, 26% blood hound and 10% boxer. He’s got a big personality, he needs a little space to run, he knows some basic commands but needs a little more training, he loves to play keep away with his blanket and toys, he’s a very sweet boy and he loves to know what you are doing at all times. He is an indoor and outdoor boy. If he’s outdoors he sits at the window waiting to come inside. Atlas is very loving and wants to be in your lap even if your lap is lower than his head. He’s a very good boy. I’m not looking for any adoption fee. I just want him to have a great home to call his furever home.

Story

🐾 Sweet, Trained Dog “Milo” Looking for His Forever Home 🏡❤️ Meet Milo — a gentle soul with a big heart and an even bigger smile. Milo has come such a long way and is now ready to find the loving forever home he truly deserves. Milo is a young, well-mannered dog who has completed professional training in both behavior and obedience (all paid and up-to-date). He knows his commands, listens beautifully, and thrives on routine, patience, and affection. His trainers describe him as eager to please, loyal, and deeply affectionate once he bonds with you. He enjoys long walks, belly rubs, and being close to his people. Milo has a calm energy indoors but is always up for playtime and adventures outside. He’s crate-trained, house-trained, and responds very well to gentle leadership. Milo has worked hard to become the wonderful companion he is today — now all he needs is someone who will give him the love, time, and stability he’s earned.
