A combination of several mastiff breeds as well as boxer, rottweiler and german shepherd - Nino does not mess around about his property and people. Nino has worked hard over the last 8 months on seeing strangers at a distance without feeling defensive but he does need continued support and the right environment to call home. His behavior is all guard dog - so expect barking if a stranger is at the door or outside of your fence. At home with his family he’s a sweet boy but still energetic and working on proper manners. He cuddles well and likes affection. Nino also likes to run around the house with your socks and shoes, but doesn’t chew them up. He just likes to carry things. He is dog friendly with males and females - even has an 8lb best friend. Nino loves to play tug of war with people and play with the other dogs in the house, and otherwise will lay and chew a bone or sunbathe. If you’re looking for a dog to make you feel safe while cuddling in your bed, Nino might be for you! He's crate-trained and housebroken. Up-to-date on his shots and neutered.

Story
If you’re looking for a dog that brings the energy and the charm, Octane is ready to rev up your life. This smiley boy lives up to his name with enthusiasm for just about everything — making friends, learning new things, and having a blast with his fellow pups. Octane is super friendly and approaches the world with a happy-go-lucky attitude that’s impossible not to love. He’s eager to learn new tricks and would thrive with a family excited to continue teaching him all the fun things a smart, motivated dog can do. Treats, praise, playtime? Octane says yes to all of it. When it’s time to socialize, Octane shines there too. He does well playing with other dogs and would love a canine buddy or regular playdates to help burn off some of that joyful energy. With his big grin, playful spirit, and lovable personality, Octane is the kind of dog who turns ordinary days into adventures. All he needs now is a home to call his own. If you are interested in a meet and greet for adoption for Octane, please fill out an application on our website at www.gatewaypets.org/adopt. If you are interested in learning more about Octane or the adoption process at GPG, please email placement@gatewaypets.org All of our dogs and cats will be microchipped, spayed or neutered, and up-to-date on vaccinations at the time of adoption.

Story
🩷I learned much about adorable Meryl Streep yesterday as we buddied up and attended CARE’S Adoption Event at “Tower Grove Pride” event. This adorable one and a half year-old pup showed her happy self from the moment she jumped in the car and was the perfect backseat rider. 🩷As we walked to CARE’S tent Meryl walked well on the leash. The event was well attended and this sweet pup was friendly and sweet throughout. As participants of all ages came up to say “Hi” and gave her pets she was gentle to everyone. As other dogs passed she was mostly indifferent being content and enjoying the moment. When this precious girl was tired she laid down and fell fast asleep and stayed like that as the action continued all around her. After her short nap we headed back to the car. This precious, perfect girl made the day’s event fun, happy and totally enjoyable for me her sidekick💕 🩷All I could think is this fabulous pup belongs in a loving home and hopefully soon! Meryl Streep, is a treasure and would be a cherished pup for many families. -Her eye condition is called Cherry Eye and is not serious and will be taken care of by CARES clinic when she’s adopted. 🩷She is at CARE STL for you to meet and possibly fall in love just like me🩷🐾XOXO

Story
Bagels is an adorable 11-month-old Mastiff mix (we suspect there's a little Boxer in her!) who is the very definition of a tiny lap puppy disguised in a big, beautiful body. This goofy girl has absolutely no clue how big she is, and she'll try to climb right onto your lap to melt you with her big brown eyes and sweet face! Bagels is a true Velcro pup who will follow you everywhere, convinced that your personal space is her personal cuddle zone. But with a face this cute, who needs personal space? She's quite smart, too, and is great motivated, which means she's quick to follow commands. Bagels is reliably house-broken (for the most part!) and loves sleeping comfortably on her own couch, going for walks around the neighborhood, and goofing around in the backyard. She's ready to fill an active home with love, snuggles, and endless laughs!

Story
✨ Meet Zaffre! ✨ Zaffre is a 5-year-old mastiff/pit mix weighing about 85 lbs of pure love and goofiness. He’s been with us for about two weeks, and he has truly been the best house guest. When we met Zaffre at the shelter, he had only been there a couple of days after coming from a neglected situation with 7 other dogs. Despite his rough start, Zaffre has settled into home life beautifully and continues to show just how special he is. 🏡 In the home: • About 90% potty trained (a few marking accidents in our unfinished basement) • Great with our female GSD • Tolerates our two cats • Treat motivated with no signs of food aggression 🐕 Personality & training: Zaffre is a big, goofy lug with the sweetest soul. He’s curious and clearly experiencing many things for the first time, taking it all in with wide-eyed wonder. Because he’s a big boy, he can pull on the leash when he really needs to go, but he responds well to correction and wants to do the right thing. ✂️ Health: Zaffre was neutered last Friday and is recovering very well. Zaffre deserves a loving, patient forever home where he can continue to learn, feel safe, and be cherished. If you’re looking for a loyal companion with a gentle heart and a silly side, Zaffre just might be your perfect match. 💙
