Story

Bear is an 11-month-old Mastiff, possibly mixed with Cane Corso. He's brown, about 120 lbs, and still growing, with a heart just as big. He loves his people, gets along well with other dogs, is fully house-trained, and walks nicely on leash with a prong collar. The truth is, Bear doesn't know how big he is. He still thinks he's a lap dog, and his love comes at you at full speed. My elderly parent visits often, and so do my young nieces. As sweet as Bear is, one happy lean or excited greeting could knock any of them down and cause a serious injury. I want to be fully transparent about his health. Bear has a seizure condition that his vet is actively managing. He's on levetiracetam and has had three episodes over the past three months or so. He's a happy, normal dog between episodes, and I'll provide complete vet records and stay available to his new family for any questions.We are not surrendering him to a shelter. Bear will stay safe at home with us until the right match is found.

Boo! Did I scare you? Don’t worry, I’m just River, your friendly neighborhood gentle giant! I may be a BIG boy, but underneath all this dog is an even bigger sweetheart with a goofy personality that’s sure to keep you laughing.

Skip the tricks, I’ve got all the treats (and cuddles) you could ever need!

Story

Meet Kip — Your Future 90-Pound Lap Dog! Looking for a best friend who gives the biggest hugs, has the sweetest heart, and thinks he's the size of a Chihuahua? Then meet Kip! Kip is a 2-year-old neutered brindle Mastiff/Pit Bull mix weighing about 88–90 pounds of pure love. Don't let his size fool you—he's the definition of a gentle giant. His favorite place in the world is wherever you are because personal space simply doesn't exist in Kip's world. He's fully potty trained, knows sit, paw, and down, and he's even working on roll over... although he usually only makes it halfway before deciding that's good enough. Kip still has that joyful puppy spirit. Sometimes he gets so excited that he gives tiny playful "love nibbles" (never aggressive), and he greets everyone like they've been best friends forever. Whether it's people or another dog, Kip's whole body wiggles with excitement when making new friends. Kip's Favorite Things: Belly rubs, scratches, and being brushed Long walks (his absolute favorite!) Tasty treats Playing with dog friends Cuddling on the couch... even if he takes up the entire couch One of Kip's cutest little quirks? He isn't a fan of walking when it's dark outside. Early evening walks and backyard potty breaks are no problem, but nighttime walks? He'd much rather wait until the sun comes back up. Kip is also wonderfully goofy. He occasionally startles himself, making everyone around him laugh. His silly personality is guaranteed to brighten even the hardest days. Because of his size and energy, Kip would thrive with a family that has a large fenced backyard where he can stretch those long legs, zoom around, and soak up the sunshine before coming inside for cuddle time. Cats are currently an unknown, but Kip does well with dogs and loves meeting new canine friends. The Perfect Home for Kip* A family ready for lots of love and cuddles* A home with a spacious yard* Someone who enjoys daily walks* Plenty of treats (he definitely won't complain!)* Bonus points if he has a dog sibling to play with! Kip's foster mom rescued him and loves him dearly. While she's nervous and excited for him to find his forever family, she would love the opportunity to remain a small part of his life through occasional updates or photos as he begins his next chapter. Kip isn't just a good dog...He's the kind of dog that changes your life.He's goofy, gentle, endlessly loving, and has the biggest heart you'll ever meet. If you've been searching for a loyal companion who will make you laugh every day, give the world's best cuddles, and love you with his whole heart. ##2803300##
