Story
We adopted Lola in October 2025 when she was 10 weeks old from a friend whom just had a litter of pups. We have been happy with her so far however our living situation changed in February when my elderly mom moved in with us and needs full time care. Lola needs lots of attention and play time which we are unable to offer with all the needs of my mom. We just want her in a loving home with someone who will give her the time and attention she needs. She’s very loyal and loves to cuddle. Our older pug and main coon cat get along with her great. She’s friendly and quite strong, so she needs a family that can handle her strength.

Story
Howdy there, I’m Chuckles. I’m a 4 year old, 80 lb. Mastiff mix with a big heart, a bigger frame, and a personality that just needs a minute to shine. I can be a little nervous when I first meet new people or find myself in new situations. I like to take things in slowly at first, make sure everything feels safe, and confirm you are not secretly a broom or a suspicious moving object. Once I realize you are kind and safe, I come out of my shell pretty quickly, especially if you have treats. Snacks are basically my love language. A few good treats and suddenly I am your best friend, emotional support giant, and personal shadow all rolled into one. I am a very sweet boy who loves affection from my people. I enjoy leaning in for pets, hanging out close by, and being part of whatever is going on. I may be large, but I have a very soft heart and I am happiest when I am near my humans. I also enjoy going on walks and adventures, taking in the world at a steady, thoughtful pace while I sniff everything that might possibly be important. I do well with other dogs and enjoy their company. As for cats, I have lived with a cat before and did well. I would do best with kids over the age of 6 who understand that I may need a little space when I am first adjusting or feeling unsure. Once I settle in, I am affectionate, goofy, and deeply loyal, but I appreciate people who let me warm up at my own pace. So if all of this sounds amazing to you, please come and meet me! My adoption fee is $295 and I'm neutered, vaccinated and microchipped. Apply to meet me today!

Story
Dozer is a neutered male, black/white Mastiff Hi! I'm Dozer! I am deaf! I really don't know how to play. It’s kind of sad. I have a little routine here - I just go in my pen, eat a few bites, drink then run back out for a treat. I like being near my people & will follow you around. I am not interested in playing ball. I really just don't know what to do with myself other than just enjoy life. I am so sweet, according to my foster. So if you don't mind a good-sized velcro dog, I'm your guy! ##2498995##

Story
At 108lbs this big boy is basically a weighted blanket with legs. Lee is a gentle giant, professional tail wagger, expert couch hog, and full-time happy boy! Despite being approximately, the size of a baby rhinoceros, he is incredibly sweet, gentle, and convinced he belongs in your lap. He would prefer to be your one and only canine king as other dogs aren't really his thing. Honestly, he'd much rather spend his time focusing on his true passion. Snacks! Cheese? Amazing. Treats? Incredible. The sound of a bag opening from three rooms away? Life changing! His hobbies include smiling at everyone he meets, taking up most of the bed, and supervising all kitchen activities in case food accidentally falls on the floor. If you've ever wanted a best friend who looks intimidating but is just a giant marshmallow powered entirely by love and snacks, this big lovable goof is your guy!
