Story
If you're looking for a sweet, easygoing companion with a playful spirit and a heart full of love, Marty might just be your perfect match! This gentle boy has a wonderful balance of playful energy and relaxed charm, making him a lovely addition to a home looking for a loyal four-legged friend. One of Marty's greatest qualities is how beautifully he gets along with other dogs! Currently living in a foster home with five canine companions, Marty has proven himself to be a fantastic member of the pack. He loves a good game of chase, enjoys spending time with his doggy friends, and has a naturally polite play style. Marty has a great understanding of canine communication and knows how to express himself appropriately during playtime. With his medium energy level, he's always happy to join the fun but equally content enjoying a relaxing afternoon. Want to see Marty's sweet personality in action? Watch his video and get to know this handsome boy! https://youtu.be/Szo22xl7M8Y Marty has a gentle, thoughtful approach to making new friends. He enjoys greeting people with a curious sniff and appreciates having the opportunity to get acquainted at his own pace. As he becomes familiar with his surroundings and the people around him, his affectionate and loyal personality continues to blossom. He's the kind of companion who makes building a special connection feel incredibly rewarding. At home, Marty enjoys a comfortable routine and has experience relaxing in his crate. He may share a little farewell whimper when his favorite people head out, but he settles in nicely. He also enjoys getting outside to explore and would love a family who can continue helping him develop his leash manners. Marty occasionally gives one of his legs a little rest after an exciting play session, so having the flexibility to enjoy activity at his own pace would be wonderful for him. Marty would thrive in a peaceful, loving home where he can enjoy the best of both worlds: fun adventures with a canine companion and plenty of opportunities to unwind. A medium energy dog sibling would be an especially wonderful match! Whether it's a home with a yard or an easily accessible apartment, Marty would appreciate a comfortable environment and a family who enjoys life's simple pleasures. With his gentle heart, wonderful doggy manners, and playful personality, Marty has all the makings of an incredible best friend. He's ready to bring companionship, happiness, and a little extra sweetness to his forever home! https://adopt.animalsfirst.com/animal/62cc8e128b02916730334440/6a554f70882fd6dddf02582f Questions?

Story
Bear Your Main Man is 110 pounds of handsome, and he takes up a very satisfying amount of space beside his person. He’s loving, enjoys being sweet-talked, and is happy to keep you company while you go about your day. His size certainly makes an impression, but the affection is what will have you making room for him at home. And possibly shopping for a bigger dog bed. Go watch Bear on YouTube to see this gorgeous guy out for a stroll, enjoying a drive around town, and soaking up all the love. Copy and paste his YouTube link into your browser: https://youtu.be/NqSan7VHckM We believe Bear is a Mastiff mix, with a look that reminds us of a Neapolitan Mastiff, though his breed is our best guess. He’s gorgeous, substantial, and a surprisingly low-key for a dog who has such a presence. At home, Bear is happy to putz around with you. Going into the kitchen? He might come along. Settling in for a quiet evening? Wonderful. He’ll find a spot to stretch out and become a very large rug. Being near his person and having somewhere comfortable to lounge suits him perfectly. Bear seems especially drawn to women, men are welcome but can you blame a big boy for having heart for a lady? Of course not! For a woman who loves big dogs, his devoted company and impressive presence is a lovely combination. He’s easy to picture beside you during a quiet evening, close enough for an occasional head rub while you unwind. He’s also a wonderful car companion. Bear generally hops right in and settles nicely in the back seat, ready to enjoy the ride. After a longer walk, a little sweet talk may help him decide to make the hop but its no trouble at all despite his size. And if there’s a chance to catch a breeze through an open window, he will be extra pleased to tag along on whatever adventure you choose. Walks with Bear are enjoyable, too. He has a great pace and walks nicely on leash. Squirrels can catch his attention, but he responds well to guidance. At 110 pounds, he’ll need a confident handler who is comfortable managing a large dog and can help him keep his enthusiasm about those pesky squirells in check. Bear knows sit, shake, and down, and he takes his treat payments gently. He also loves the water, so a chance to splash around would be a lovely addition to his otherwise fairly chill and leisurely agenda. If you ask Bear what his dream match would be we are sure he would say - a home where he is the only dog so he can enjoy his people all to himself. That does not mean dogs are not welcome but Bear doesn't need them to be happy. One of his current doggie friends is an easygoing female dog who understands all he wants is peaceful companionship and will pass on wrestling or chasing. Good company on a walk, a handsome passenger in the car, and a big, loving presence at home—Bear is ready to be your main man. A little sweet talk, some room to stretch out, and a person to adore would make him very, very happy.

Story
Meet Biggy, a lovable Mastiff mix who is making up for lost time and discovering that being a dog is actually pretty great. The Notorious D.O.G. is officially looking for his forever crew. And yes, he loves it when you call him Big Poppa. Kids: Biggy has been around children, but because he’s a big guy still learning about the world, he’d do best in an adult home or with kids 13+. Dogs: Biggy seems to enjoy having canine friends! He’s still polishing up his doggy social skills, so slow introductions will help set everyone up for success. Cats: Cats are a brand-new category for Biggy, so we don’t know what he thinks of them yet. Personality: Big, sweet, curious, and still discovering all the perks of being someone’s best friend. Dream home: Someone patient, consistent, and ready to celebrate all of Biggy’s firsts—the first favorite walking trail, the first ridiculous toy obsession, the first perfect couch spot, and everything in between. Birthday 8/5/24 Biggy’s past may have been pretty boring, but his future definitely doesn’t have to be. This gentle giant has a whole lot of life to catch up on, and he’s ready to find the person who wants to experience it with him. Being fostered in Raymond, Washington. Biggy's adoption fee includes his neuter, microchip and all his adult vaccines
