Story
On October 30th, 2024, a Good Samaritan found this big, beautiful dog chained to the fence behind our business. They took this sweet boy in and named him Lincoln. They have been incredibly fostering him ever since, but he would love nothing more than a forever home!! If you are interested in adopting this sweet boy, please email us at info@scoutshonor.org. See what his amazing fosters have to say about him: “Not sure how long he had been there but he was left there looking so sad, with no food or water. We only go out there once a week so it was a blessing that a contractor found him. After we discoveredhe was friendly, we unchained him and took him inside. A trip to the vet showed he was microchipped from a shelter in Petaluma, CA where he was adopted in 2019. He is a 6-1/2 year old beautiful, fawn and white Mastiff/Great Dane. He stands 26" at his shoulders, 33" top of head to floor and weighs in at 98 pounds. Here is a big ol' sweet boy that absolutely loves people! We've had him for a while so we know there is absolutely nothing negative that we can say about him. There’s no useless barking. If he does, it’s for a good reason. He’s the best at letting us know the doorbell is ringing. Intelligence and memory are not lacking. He’s already trained with commandssuch as sit, down, stay, back, shakes hands with either pawand speaks on command. A gentleman he is, has never had an accident inside, loves walks/runs and walks calmly on a leash the majority of the time. He would benefit from a little more training. And just to let you know, he’s very strong. He's quite alert and when outside and is always looking around and observing. He will just stop and stand still, nose into the wind, looking around intently. And running! He loves to take off and run like a thoroughbred. It’s a beautiful sight.Loud noises never make him flinch. He loves to sniff around cars/tires but never does the “typical dog thing” on tires. He’s calm and oh, so lovable. His fur is very soft which makes him so huggable. Hanging out in the sun on his special carpet is one of his favs. This guy loves to be sung to, spoken to lightly and loves secrets whispered in his ear. He will look you in the eyes and you would swear he’s reading your mind. Try and win a staring contest with him. Bathing at the Self Serve Dog Wash at PetCo is a fun time for him, or so we like to think. Scrubbing and pampering him like the Cowardly Lion from the Wizard of Oz is a special treat.He's so patient. We’ve come to find out he is quite exceptional. Say the words “wanna go?” and he’s ready. He gets so excited and heads to the door and then to the back of the SUV to jump in. He puts his front paws on the console, navigating every turn and loves to stick his nose out the window to see the sights and smell the new aromas. We’ve named him Lincoln…as in Abraham. What does Lincoln mean spiritually? Lincoln signifies deep wisdom and emotional depth. The name suggests overcoming emotional challenges and finding fulfillment. That fits him to a “T”. He no doubt has had some emotional challenges, even though you would never know. Finding a Furever Family to love him would be that fulfillment. He’s up to date on all vaccinations. Because of his size and his tail that wags with gusto, he probably would not be good around small children or possibly cats. He does get along with other dogs as long as they don’t pick on him.” April 14, 2025, 11:35 pm

Story
This is one of the hardest decisions we’ve ever had to make. Lady Bird has been a beloved part of our family, our loyal companion, and our gentle friend. She’s brought us so much joy, love, and laughter. But with heavy hearts, we’ve come to the decision that we need to find her a new home. Our 1-year-old daughter was recently diagnosed with a pet allergy. We’ve done everything we can to manage it—keeping Lady Bird mostly in her crate, limiting contact—but it’s becoming clear that it’s not a long-term solution. And now that we’re expecting another baby, it’s becoming even harder to juggle it all. This decision is not about Lady Bird—she is an incredible dog with so much love to give. It’s about doing what’s best for our family, especially for our children’s health and well-being. We never imagined having to let her go, but we know she deserves a home where she can run freely, be close to her people, and get all the love and attention she deserves.
