Michigan, USA. 🇺🇸 I'm the breeder behind ACM Mastiffs located in Frederic, MI. At ACM, I hope to spread the love of the Mastiff far and wide. I believe this incredible breed should be in almost all homes! My dogs are bred for health, temperament, quality, longevity, and conformation. I believe in any and all health testing, and I strongly think that any potential 200-pound dog should have the best

start at life. The Mastiff is a wonderful breed that truly is one of a kind! I would be honored to connect you with your next Mastiff puppy!

🏡 Seeking a Loving Home for Our 4-Year-Old Male Mastiff 🐾

We are looking for the perfect forever home for our sweet 4-year-old male Mastiff. He is:

• Kennel & potty trained
• Great with other dogs
• Has not been around cats, but we don’t anticipate issues
• A true gentle giant – total couch potato energy
• Loves being outdoors
• Amazing with children, especially little ones
• Excellent on a leash – no pulling
• Calm, affectionate, and loyal
• DNA clear, some OFAs completed-

He embodies everything people love about the breed: laid-back, loving, and devoted. - with a little hesitancy towards new people.✨

He also has a few AKC points ✨

Rehoming fee: cost of neuter only
This is to ensure a serious, committed home.

We are being very selective and want a family who understands the breed and will cherish him as a member of their family. If you think you might be the right fit, please message me privately.

With the recent and unexpected passing of Andromeda, ACM Mastiffs has come to a halt.

She was not only my soul dog, but also my only female. From the very beginning, ACM was built with intention — we never aimed to be a large breeding operation or house multiple females. Everything we did was rooted in ethics, purpose, and integrity.

Losing Andromeda has been devastating. I won’t pretend I’m excited to return to the mastiff community, because I’m not. At the same time, I worked incredibly hard to build ACM, and closing this chapter isn’t easy.

Everything I know, I learned beside this dog — ethics, showmanship, loyalty, honesty, pain, devotion. This breed is unlike any other, and it was truly an honor to be owned by Andromeda.

For those who may not follow my personal page, I wanted to share that for the foreseeable future, my mastiff journey has come to an end.

That said, I may be venturing into the Xolo world around March. If that’s something you’re interested in, I invite you to continue following along.

Thank you for supporting ACM Mastiffs & Xolos. What a privilege this journey has been. 🖤
