Story

Hi, I’m Orville. I am a senior boy looking to relax in a home for my golden years. I will need typical senior care special needs. Dog’s Name: Orville Location: St. Joseph, IL Date of Birth: 06/28/2017 Gender: Male Breed: Mastiff Mix Color: Brindle Dog's Weight: 118 Gets along with: Dogs?: All Dogs Cats?: All Cats Kids?: Have not tested with kids Training: Leash trained: Walks loose on leash Crate/Kennel: Goes into crate/kennel on command Potty trained: Indicates a need to potty and doesn’t have indoor accidents Car: Rides Well in car Meet Orville Orville is the definition of laid-back love.This tall, gentle boy is happiest right by your side — truly your shadow in the very best way. Whether you're moving from room to room or enjoying a quiet afternoon, Orville will calmly stroll along beside you. He’s a pleasure on walks and just as easy in the yard, where he prefers to stay close rather than wander. Orville is wonderfully quiet and only speaks up when it’s time to head outside. His house manners are impeccable — he has his potty routine down perfectly and hasn’t had a single accident in foster care. He politely sits for his food bowl and treats, and at this stage in life, he’s more about companionship than chaos. While he may be a little slower these days, that just makes him an easy keeper and an incredibly devoted companion. Orville is quiet and well mannered, great on walks, fully house trained, does not require a fenced yard, will do well as an only dog or with a calm buddy, and an excellent choice for a first-time giant breed owner. Orville isn’t looking for adventure — he’s looking for connection. If you’re hoping for a steady, gentle presence who will faithfully follow you through life’s simple moments, Orville is ready to be your loyal best friend.

Story

Hi, All Mac, here short for Mac truck lol. If you love big goofy dogs, I'm your guy. I am 100 lbs. of cuddle bug. I really don't think I am as big as they say I am because I would prefer to just be a couch Potatoe and lay next to my people and chew on a bone. I am a people kind of guy and love everyone I meet. I can probably live with another dog, but he would have to be calmer like me. but little dogs and very young children I would be afraid of because I am clumsy and wouldn't want to hurt them. I definitely don't think I could handle cats. But I know a lot of commands they say I am really smart and a fast learner. I am potty trained but do not like cages. I am strong on a leash so I would need a strong owner. Fill out an app here. https://docs.google.com/forms/d/e/1FAIpQLSdsHBf5NUtvyBYpzWm6Z5Z0JosLBTsDC98oxPTfxtM9brrc7Q/viewform

Story

Hi, I’m Everest and I’m new to the rescue. I am currently decompressing and getting used to my foster family. Check back as my foster family learns more about me! Dog’s Name: Everest Location: Green Bay, WI Date of Birth: 03/06/2022 Gender: Everest Breed: St. Bernard Color: Dog's Weight: 106 Gets along with: Dogs?: All Dogs Cats?: All Cats Kids?: All kids Training Leash Trained - walks loose leash Potty Trained - indicates need to potty and doesn't have indoor accidents Car - Rides well in the car Meet Everest Everest is a wonderfully laid-back and loving girl who thrives on being close to her people. If you’re looking for a loyal companion who wants nothing more than to spend time by your side, Everest may be the perfect match. She will happily follow you from room to room—even while you’re vacuuming—just to stay near the people she loves. Everest’s favorite place in the world is the couch, especially if she gets to share it with you. She absolutely loves being petted and will gladly soak up all the affection you’re willing to give. While some pups are obsessed with toys and bones, Everest is much more interested in companionship. For her, the best activity is simply relaxing next to her favorite humans. She is not crate trained and prefers not to be crated (unless you plan to join her in there! ), but the good news is that she does very well when left alone in the home. Everest is respectful of her space and doesn’t chew on things she shouldn’t. At night, she’s perfectly content to curl up on the couch and sleep peacefully through the night. Everest can sometimes feel a little nervous in new situations and may grumble or growl briefly when meeting new people, but she warms up quickly once she realizes she’s safe. Outside, she may bark at unfamiliar sounds, but inside she’s a quiet and easygoing housemate who doesn’t spend time barking out the windows. During mealtimes, she is very polite and will calmly lay near the table. Everest would do well with a variety of families, including first-time giant breed owners. She doesn’t require another dog in the home but could live with other pets with proper introductions. While she currently enjoys having a fenced yard, she doesn’t necessarily require one as long as she gets regular outdoor time. If you’re looking for a gentle, affectionate companion who will happily keep you company on the couch and throughout your daily routine, Everest is ready to be your loyal shadow.
