Story
Hephaestus is a 5-month-old Alabai x Boerboel mix with a big personality and an even bigger heart. She’s already had her vaccinations, been dewormed, and is crate trained—so she’s off to a great start! She’s playful, smart, and full of energy. Always up for an adventure or a game of tug. She’s also incredibly affectionate and intuitive—she loves being close to her people and is quick to form strong bonds. With her mix of two powerful guardian breeds, she’s naturally confident and observant, but also gentle and loving.

Story
Great news! My adoption fee has been paid by someone who loves me and wants me to find a great home.Here's what you need to know about me:I'm big, but I'm also a very gentle girl. I can be shy and a bit fearful in new spaces and around new people. I need a family who will let me take things at my own pace as I learn about new things. Loud noises startle me at first. Once I come out of my shell, I have lots of love and cuddles to give.I love to be around my people. I would love to take calm walks and sniff around then rest and lie down close to you. My human friends at the shelter can tell you more.It's recommended I meet any dogs or kids living in my new home before I'm adopted. Kids over 10 would work out best. I just want to make sure we all get along. Primary Color: Tan Secondary Color: Black Weight: 86 Age: 5yrs 0mths 3wks

Here's what you need to know about me:I'm easy going. Wanna go for a walk? Okay. Hang out in the yard? No problem. Just relax on the couch? I can do that. I'm pretty happy to go at your pace and I don't really need much more than most dogs do. If you're looking for a steady companion, I'm all yours.It's recommended I meet any dogs or kids living in my new home before I'm adopted. I just want to make sure we all get along.I need a space of my own. I sometimes have a hard time sharing my treats, toys, or bed with other pets. Ask an adoption counselor for more information.

Story
You can fill out an adoption application online on our official website. Bruhno Bruhno is still a work in progress.  Bruhno is a very shy English Mastiff.  He is learning to walk on a leash and ride in cars. Bruhno is good with other dogs and was raised with children.  It will be a while before we feel he is ready for adoption. His future "furever" family will need to be prepared for the long haul. Bruhno is terrified of new situations.  His main and immediate response is to immediately empty his bladder  Any adopters will have to be prepared for this.  He is house trained; this is a fear response. If you are interested in Bruhno or any of our fosters, please go to our website at www.mastiffrescueoregon.org, click on adoption info, and submit an application online. An application is required for any meet and greet. All of our fosters are in private homes.  Please be courteous, and do not call prior to 8:00am or after 8:00pm  Visit this organization's web site to see any additional information available about this pet.November 3, 2024, 12:21 am
