Story
Here’s a more polished and engaging version of Cali’s bio, with added details about her living situation with young children in her foster home: --- **Meet Cali!** 🐾 Cali is a stunning 1-year-old, 50-pound Boxer mix with a heart as big as her smile. This sweet girl has already been through so much in her young life—she was found as a pregnant stray and bravely brought nine beautiful puppies into the world in August (all of whom have found their forever homes—yay!). Cali was the most devoted and loving momma, and now it’s her turn to be spoiled! Unfortunately, Cali was heartworm positive when she was rescued, but she’s a fighter! She has completed her treatment and is on her way to being heartworm-free, leaving her life of neglect behind her. Cali is ready to start a new chapter with a family who will cherish her for the rest of her years. Cali is an absolute love bug who adores people of all ages. She’s currently living in a foster home with several young children and has proven to be gentle, patient, and playful with them. She’s also great with other dogs and could potentially learn to live with a cat, though her playful nature might be a bit too much for some feline friends. With her adventurous spirit and affectionate personality, Cali is the perfect companion for an active family or individual looking for a loyal, fun-loving partner. Whether it’s exploring the great outdoors or snuggling on the couch, Cali is ready to bring joy and love into your life. If you’re looking for a sweet, resilient, and energetic girl to join your family, Cali might just be the one for you! 🐶💕 Please apply at www.soardogs.org Adoption donation required.

Story
Taz came to us unexpected about 6 months ago with no home. I have heard her bark only a couple of times. She is very loyal, friendly and no matter what any cat, kid or other animal can get to her. She loves all and anyone with complete patience. It would be great if she was not left alone too long for she may get separation anxiety. A home with other fur friends and family would be great in making her feel complete. If I had to guess I would say she is just over 1 years of age.

Story
Say hello to Dexter!! Dexter is an affectionate young puppy who would love nothing more- than to snuggle up in your lap and be your best friend. Dexter loves to go for car rides, play in the water and just be by your side. He is doing well with potty training and rarely has an accident. Dexter is not a big fan of his crate but does settle down nicely and sleeps through the night. He is still learning his manners and currently working on commands like sit, down, place and come. He is getting better walking on the leash but could use more practice. With Dexter's love for treats, he's eager to learn and impress! If you are looking for a loving companion with lots of potential, Dexter is your guy! Highlights: **Potty trained **Crate trained **Loves car rides **Affectionate

Story
Oh boy, oh boy, oh boy! Everyone stop what you're doing and watch as Mr. Bongo Wongo tippy taps his way into your hearts. Bongo's favorite things are people, people, and more people! He is a "social eater", only wanting to dig in under the watchful eye of his favorite people. This 4 year old goofball is here at Five Acres through no fault of his own. He has experience living with smaller dogs as big dogs are a little scary to him. We are unsure of how he would do with cats but can provide instruction on a proper cat introduction. Bongo has valuable home experience, making him an ideal addition to any family. He is house-trained and understands basic commands, showcasing his adaptability and eagerness to please. Bongo is accustomed to a routine and thrives in a loving environment, where he can engage in playtime and quiet moments alike. His previous experiences in a home setting have shaped him into a well-mannered companion, ready to bring joy and companionship to his new family. If you are interested in meeting with Bongo, please send in an application so we can set up a meet and greet as he is currently in foster!

FIONA Hey there, fabulous humans! Fiona here, your future queen of the castle. Backyard Queen: Give me a fenced yard and watch me turn into an explorer worthy of my own adventure series. Leash Diva: Yes, I'm strong on the leash - blame my renewed post-mom vigor. We're working on it, but hey, a girl's gotta have some muscles! Escape Artist: Quick heads up-I'm a pro at the sneak-and-peek when you're grabbing the mail. It's not being nosy; it's called being thorough. Picky Playmate: I vibe with my 55 lb. male dog buddy, but my prey drive is high, so small dogs and cats might want to sit this one out. Selective Socialite: Older kids? Cool. Younger tots? Let's not. And gents, I'm a lady who prefers to keep her distance, so let's not push it. Cautious Charmer: I'm not a fan of men-personal preference! So, let's keep our interactions ladies-only, or I might have to lay down the law. Living Situation: Ideal home? Adult-only, no other pets, and a yard to call my own. Crate trained and housebroken, because even divas have standards. The Sass: If you're looking for a loyal, loving companion with a touch of sass and a whole lot of personality, then look no further. So, think you can handle all this pawsomeness? If you're ready to meet a lady with charm, smarts, and a little bit of an attitude, let's make some magic happen! Note: Fiona is a 6.5-year-old pit mix with a loving yet discerning personality. She thrives in environments that respect her boundaries and provide the affection she eagerly offers.

Hello, I'm Huey Lewis, a gentle soul who's had more than my share of goodbyes. With the loss of my dear buddy Lewie Armstrong, who crossed the rainbow bridge, and both my mom and foster mom facing health issues, I find myself searching for a new heart and home to heal in. My Story: I was always the shyer one, relying on Lewie for confidence. Without him, I'm a bit lost, but I'm slowly finding my way back with the help of some tasty treats and gentle souls. I'm a testament to resilience and the quiet strength that comes from enduring. What I Need: 🏡 A Patient Home: I thrive in an environment where patience and gentleness are abundant. 🐾 Dog Selective: I'm okay with submissive dogs, but proper introductions are crucial because I appreciate a peaceful and respectful canine companion. 🛋️ Moderate Energy: I enjoy a good balance of activity and rest, making me a great companion for someone who appreciates a moderate pace in life. 🧸 Cautious & Shy: It takes me a little time to warm up, but when I do, I'm all about quiet companionship and leaning in for some loving pets. 🚽 Housetrained: No need to worry about accidents; I'm well-versed in home etiquette. 💕 Friendly: Once I feel secure, my sweet and loving nature truly shines. Why I'm Worth It: Though I'm cautious, the bond we'll form over time will be filled with loyalty, affection, and quiet moments of contentment. All I want is to feel safe and loved, and I promise to be a devoted companion in return. Ready to Give Me a Chance? If you have room in your heart and home for a pup who’s looking to love again, I'm your guy. Let’s meet and see if we can find comfort in each other’s company.
