Story
Hawkeye & Remi – Bonded Seniors with Big HeartsHawkeye – 10-year-old Black Lab MixHawkeye is a gentle senior who enjoys the simple things in life—sunshine, fresh air, and a good shady spot to settle down after making sure the yard is safe and secure. He takes his “security patrol” duties seriously, then happily retires to relax and enjoy his day.Hawkeye is house trained on a schedule of about 6–7 hours and currently benefits from a midday let-out to comfortably do his business. He requires a fenced yard, as this is where he prefers to potty and spend time exploring at his own pace.He does well on a leash and is continuing to improve with short morning or evening walks, which also help manage his arthritis. His arthritis is supported with a Cosequin supplement, and he should wear a harness instead of a collar due to laryngeal paralysis, which can be aggravated by heat or pressure on the neck. Because of this, mid-afternoon heat is avoided for activity.Hawkeye is social and gets along well with other dogs. He also showed no adverse reaction when meeting a cat at the veterinary clinic.Remi – 8-year-old Border Collie MixRemi is the more active of the pair and a classic border collie at heart—intelligent, observant, and always keeping an eye on the world around him. He enjoys running in a fenced yard and making sure everything in the neighborhood is running “on schedule.”He is affectionate and loves spending time with his people, often resting his head in your lap while you relax in the evening. Remi enjoys companionship and attention just as much as activity.He does well with other dogs, though he has not officially been tested with cats—based on his temperament, there are no immediate concerns, but this is not confirmed. Remi is also learning leash skills and enjoys 2–3 short walks daily.He does best when crated in the morning, as he can occasionally have accidents if left loose during that time.TogetherHawkeye and Remi are a sweet, bonded-feeling pair who enjoy each other’s company and bring out the best in one another. They balance each other beautifully—Hawkeye’s calm, easygoing nature pairs perfectly with Remi’s playful curiosity and intelligence.They are both loving dogs who enjoy companionship, routine, and a safe space to relax and just be themselves.

🐾 HI, I’M TUNNEL! 🐾 Your handsome spotted boy with the nose of a detective and the heart of a marshmallow… once I trust you. 🤎 I’m a 2.5-year-old, 55-lb Retriever/Border Collie/Lab mix with the world’s cutest pink snoot and a patch over one eye that makes me look like a pirate… a very sensitive, easily-startled pirate. 🏴‍☠️💗 I’m a cautious guy who needs patience, consistency, and a calm home to feel safe. Once I decide you’re my person? I melt into your side like warm butter on toast. I’ll follow you, protect you, and be your loyal ride-or-die forever. ✨ My Stats (aka why I’m worth it): • 😳 Shy at first • 🐕‍🦺 Protective/territorial — I take my job seriously! • 🏡 Yard required for zoomies + security patrols • 💛 Moderate energy • 🚫 No cats, please (I think they’re tiny suspicious ninjas) • 🐢 A little cautious, but I try really hard Once I warm up, I adore other dogs, love being outside, and I’ll happily snooze near you like the big, spotted weighted blanket you never knew you needed. I promise: give me time, give me kindness, and I’ll give you my whole goofy heart. 👉 Click the link next to my name to learn more, apply, or schedule a meet & greet! #AdoptTunnel #SpottedSweetheart #RescueDog #StrayPawsRescue #AdoptDontShop #ShyButShining #WorthTheWork #ForeverHomeNeeded

"She ran calling "WILD.....FIRE"!! That is a haunting song.... I promise, though..I am not a HAUNTER!! But I may love to run around and around and AROUND :) I am a puppy! I am so sweet and cuddly, when i finish running around ;) I have plenty of energy so you HAVE to be ready to burn it off with mental and physical exercise. I am SMART too! Teach me who you want me to be and I will learn! I was found with 4 siblings living (dumped) at the Home Depot...but it was a LUCKY BREAK, cause we were seen by the husband of a rescuer and we got SAVED! Now I am in my foster home and learning the "ropes" ;) Potty training is getting better every day, I mean our foster mom takes us out often for potty control and I am really working hard to wait for the next jaunt outside! I also am crate training too! I don't like to pee or poop where I sleep- as long as I don't eat right before bed and go outside as soon as I wake up I am doing great!! I seriously am ready for my family, I LOVE to play and am great with all dogs big, small, old or babies. AND i have one half BLUE EYE!! The better to see you with, my new family! :) ADOPT ME SOON!! Local adoption fee is $250 (in TX) Out of state adoption fee is $550 (includes transport to your area)

Story
Hi! My name is Pattie 🍀 I’m extra lucky because my foster dad found me after I was born on St. Patrick’s Day — that’s how I got my name! Sometimes they call me “Pattie Peppa” because I can be a little piggy, but I’m pretty sure I’m actually a puppy. I absolutely LOVE my foster siblings and even my foster cat brothers too! Playing is one of my favorite things ever, and I’ve got enough energy to keep the fun going all day long. I’m super curious about everything around me — not in a naughty way, I just want to know what the world is all about! I’m full of pure puppy energy, but I’m also very loving and sweet. With a little patience, training, and lots of cuddles, I’ll make the perfect addition to a lucky family’s home. Pattie had a previously broken leg, but you’d never know it by the way she plays, runs, and keeps up with all the fun!

Now, before we go any further into my story.... let me warn you...it contains heartache and then some puppies, and fear and even some hopelessness. We do go to the top of the mountain as well, so hold in for the wild ride of my life:) maybe you will get to be my happily ever after.... So I was born a poor border collie mixed pup, in the miserable heat, in a disgusting backyard. To a mama that could have been so beautiful, if she had been brushed and cared for.... Fast forward thru almost 4 YEARS of misery and puppies, we were saved!!! I was saved with 9 newborn puppies and my sister/daughter/ cousin, etccc Princess and HER 9 PUPPIES TOO! We landed safe and sound at the rescue! We are now gorgeous girls and all pups grown and adopted! Now its time for me!! I am a single gal, and really don't like other dogs in my business. I want to be the Queen of the house :D Adopt me and I will fill YOUR home with my love and devotion. Local adoption fee is $200 (in TX) Out of state adoption fee is $450 (includes transport to your area)

Story
Shy little Millie is looking for her safe place to land Millie was surrendered to the shelter due to unforeseen circumstances, and she arrived very shut down, fearful, and unsure of the world around her. In those early days, even something as simple as a ball outside felt overwhelming to her.She is a sensitive Cattle Dog type who takes her time to trust, and she will need a calm, low-traffic home with someone experienced in helping nervous dogs feel safe at their own pace.Millie previously lived with an autistic child and was very protective and loyal to them, showing her deep capacity to bond once she feels secure.Since beginning to decompress, her personality has slowly started to peek through. When she’s comfortable, Millie enjoys zooming around the yard with happy bursts of energy. She’s also shown interest in other dogs, sometimes initiating playful behavior along the fence line—though face-to-face interactions will need slow, thoughtful introductions.Millie is: * Potty trained* Walks fairly well on leash* Best suited for a calm, patient home* Dog-selective and needs slow introductionsUnderneath her fear is a dog who wants to connect—she just needs time, safety, and someone willing to let her unfold at her own pace

Story
Meet Twix! Twix is a 1-year-old Australian Cattle Dog with a clear set of priorities: snacks, socializing, and living his best life. While staff is busy in meetings, Twix is perfectly content keeping himself entertained with yak chews and peanut butter containers — proving he’s a dog who knows how to enjoy the moment. Twix came to PAC after being found as a stray. A kind good Samaritan gave him a safe, loving temporary home before bringing him to us, and during that time, he proved to be a sweet, well-mannered houseguest. He did well with children and was comfortable being crated, showing early signs of a well-rounded, adaptable dog.Personality-wise, Twix is a social butterfly. He has never met a stranger and greets everyone with bright eyes, wiggly excitement, and a happy attitude. And if you don’t notice him arriving? Don’t worry — you’ll hear him. Twix’s unique, gentle “Darth Vader” breathing ensures his entrances are always announced. As an Australian Cattle Dog, Twix is an active, intelligent, and highly social breed. He will thrive in a home that provides mental stimulation, physical activity, and consistent training. Twix may also display herding behaviors, particularly around children, so an adopter familiar with or willing to learn about the breed will be best for him.If you’re looking for a happy, snack-loving, endlessly social companion, Twix is ready to join your family and show you how fun life can be with a devoted, goofy best friend.
