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.

This absolutely gorgeous black brindle big mushy baby boy is Rey!! This amazing pup came in with his siblings after a breeder of rare breed mastiffs had an accidental litter and couldn’t know for sure the dad.

Rey is about 23 weeks old and has had all of his medical work completed! He’s been to the vets routinely and has had his boosters, deworming, preventative, microchipping and he’s now neutered! He’s a healthy happy baby and can’t wait to begin his next chapter! Rey has adjusted so beautifully to foster care and is absolutely fantastic with everyone. He has wonderfully sweet, happy, loving puppy energy and loves to play with all people and animals he meets! He is very affectionate, loyal, and incredibly intelligent. He’s doing great going potty outside, he absolutely loooves toys, he’s great with car rides, enjoys the water, and is unbelievably snuggly. He will do great in a home with any combination of animals, or as an only pup. His big dream is parents who loves to snuggle and a yard where he can both play and relax and enjoy nature. He’s had a great foundation in foster care and is ready to start a new life with a loving home where they can continue to raise this amazing baby boy to be the incredible guy he’s destined to be!

Story
This gorgeous, black brindle, wonderfully sweet, big mushy baby girl is Canela!! This girl and her siblings were surrendered into Rescue after their owner had an accidental litter. The owner bred rare breed mastiffs, but had a few other dogs. This little girl‘s mom was a 100 lb rare breed mastiff, but they could not confirm who the father was therefore we’re looking to surrender the litter sadly. All of them have markings of rare breed mastiff, with no clear indicator that they have been mixed with anything. They were raised with a family but the family decided they weren’t interested in finding buyers, and surrendered the entire litter to their local dog pound. We were shocked when we received a desperate call for help from the animal control officers. They wanted to ensure these sweet mushy babies made it out of the shelter and into the right rescue, where they would find amazing homes! This girl is now 23 weeks old and she has just had all of her medical work completed! She’s now current on all vaccines, dewormed, she’s current on preventative, microchipped, and spayed! She’s had all the good stuff done and been given a clean bill of health- now she just needs to find her true love! Canela has adjusted very well into her foster home. She’s been fantastic with other dogs, with cats, and with every person she’s met. She has a hearty appetite and getting all the food she needs now! She’s been very social and well adjusted thus far. She has been fantastic with every dog she’s met, both littermates as well as new dogs in play groups. This girl is absolutely amazing! She’s doing great with reliably going potty outside and learning the ropes of being a well loved house dog. As we cannot know for sure her dad, we can’t know how big she’ll mature to be, but we are guessing around 90 lbs. She is extremely devoted to her people and will thrive in a home where there’s a yard, hopefully another pup, and most definitely humans who enjoy a good snuggle on the couch and would like a dog super devoted who will follow you around the house and the yard, and commit their heart to you. She’s extraordinarily intelligent and has had an excellent foundation of socialization this far. She’s longing for a home where she will be a true family member, with people like her; easy going, and committed to forever by her devoted parents. She’s intelligent and playful as she’s a puppy, loving toys and adventure and all the great things puppies can learn about the world. That said, she’s a more relaxed puppy and also just loves snuggling in her downtime. If this beautiful sweet girl is a match for you, and you’d love to adopt her, please visit www.greatdivideanimalrescue.org/applicationdogs and submit an application for adoption today!!! **NOTE** to ensure prompt response- please go directly to our website (www.greatdivideanimalrescue.org) to apply, or email (inquiries.rescuematch@aol.com) directly with any questions to ensure your inquiry/application is received by our organization.

Story
This guy has a story let me tell ya. His name is pronounced Mah-zi and means "lucky". Well he's sure lucky that somebody had the good sense to dump him in our town so that we could become his new tribe. Mazi was lovingly owned and lives in Chicopee Mass but his owner had to move and couldn't secure housing for them. He rehomed him to an older gentleman in Springfield Mass. In the span of six months, Mazi found himself dumped in CT. We did recon with his microchip and got the scoop. So now he's looking for his forever home, and preferably no dumping this poor dog. He's already been thru enough. Mazi is good with docile female dogs his size. He's a little mouthy so only older kids until he settles in and gets his bearings. We are under the impression that his mouthiness is from stress in the kennel. He loves car rides and walks. You could take him everywhere but he's strong on a leash. We will help to teach you how to walk him and use training techniques. He's not cat tested but we'd say, um no. He's getting fully vetted on 9/15/26. He can go home two days later.
