Story
Meet Sabrina, a gentle 6-year-old Mastiff mix who’s in need of a special forever home. Sabrina is living with mast cell tumors (MCT) due to cancer and is currently on medication to keep her as comfortable as possible. She requires a loving home that is prepared to offer her hospice care and a peaceful environment. Sabrina can be shy with new people and may give a warning growl or snap if approached when she’s not ready. However, once she builds trust, she becomes deeply affectionate and very attached to her people. She gets along well with mellow dogs and will thrive in a calm household where she can feel safe and loved. If you have a compassionate heart and are ready to provide a supportive and caring home for a special dog like Sabrina, you’ll find a loyal and loving companion in her.

Story
Meet Magnolia, a sweet 90-pound mastiff with a heart as big as her size! Initially nervous when she arrived at the shelter, this lovely lady has made incredible strides in building her confidence thanks to the patience and love from our staff. She’s incredibly food motivated, and nothing makes her tail wag faster than a tasty treat—especially cheese and hot dogs! Once you’ve earned her trust, you’ll discover a loyal companion who just wants to be by your side. While we suspect Magnolia spent her early days as a backyard dog, she dreams of a cozy home where she can lounge on the couch and soak up all the love. However, she may not be the best fit for homes with tiny humans. If you’re looking for a gentle giant to join your family, Magnolia might just be the perfect match! Come meet her today and see the love she has to offer.

Story
Meet Stewie, a lovable 4-year-old Mastiff mix looking for his forever home! Weighing in at 100 pounds, Stewie is a gentle giant whose biggest desires are cuddles and food. His past has left him a little overzealous when it comes to treats, so homes with small children might not be the best fit for him. Stewie is incredibly loyal and sweet, always ready to protect and love his family. He gets along well with other dogs, but due to his size and energetic play style, smaller dogs might not be the best playmates for him. Unfortunately, Stewie is not suited for homes with cats. This big-hearted boy had a rough start in life, having been starved before coming to his current foster home. Despite this, he’s shown an unwavering capacity for love and loyalty. Stewie is waiting for a family that can give him the care, attention, and endless cuddles he deserves. Please consider giving Stewie a chance to be your loyal companion! If interested please go to our website and fill out an application. You can find our application under the adoptable dogs icon. Thank you for choosing Ozzie and Friends Rescue. We can’t wait to connect you with your new fur-ever friend.  https://www.ozzieandfriendsrescue.org/   Ozzie and Friends Rescue makes arrangements for all dogs adopted to be transported all across the Western United States, Canada and Midwest.   October 24, 2024, 9:53 am

Shelter Visiting Hours are 12 pm to 4 pm Tuesday, Wednesday, and Thursday. Please fill out an adoption application at mamcorescue.org or attend one of our Saturday adoption event. Events are held each Saturday from 12:00 pm to 5:00 pm at our office: 2721 W Oxford Ave., Suite 6 Englewood, CO 80110 *In order to protect our puppies, we do not allow puppies to attend open events until they have a minimum of two vaccinations. Puppies who are available, but not listed on our weekly Facebook event, are considered "deposit only" puppies. These puppies will only attend the event IF they are reserved through a deposit. You can check the list of puppies attending the open event by checking the event:https://www.facebook.com/MAMCORescue At MAMCO we understand that in order to continue rescuing moms and babies, we must stretch our finances as far as we are able. For this reason we use variable adoption pricing. By assigning higher adoption fees to high demand moms and puppies, we are able to rescue more families in need.The money raised through these adoptions acts as a benefactor to moms and puppies in our care who require expensive veterinary treatments, have behavioral issues, or need more time to find a home. We often reduce the adoption fees on these harder-to-place moms and puppies to help them find forever families. Adoption fees vary. Applications can be filled out at mamcorescue.org. ##735151##
