Story

Hi, I’m Bones! My journey to the shelter? A classic mix-up. Picture this: I saw a squirrel, gave chase, and somehow ended up leading a conga line at a fancy garden party. Yup, crashed it! After a whirlwind of dance moves and giggles, I was kindly escorted here. I’m a smart, playful guy who can turn any dull moment into a party. Need a dash of joy and a partner in fun? I’m your pup! Let’s make every day a blast together! I am looking for a forever family or a family to love me until my forever family finds me. If you decide to fall head over heels in love and cannot part with me that is okay, too! Please call 314-951-1588 for more information!

Story

Hi, I’m Luke, and I’m a big, lovable boy tipping the scales at just over 100 lbs! Don’t let my size fool you—I’m a happy, easygoing pup who just wants to play, explore, and cuddle. I’m all about the good things in life: squeaky toys, water play, long walks, and best of all—snuggle time on the couch. I’m a pro at giving hugs (though I’m working on not jumping up too hard to give them—oops!). I get along great with other dogs and kids, but because of my size and enthusiasm, I’d do best with older children who won’t get accidentally knocked over during playtime. I’m crate trained, housebroken, and walk nicely on a leash—unless there’s a squirrel… then it’s game on! I do have a slight prey drive, so a little guidance goes a long way. If you’re looking for a big-hearted, playful companion to fill your home with love (and maybe take up some space on your couch), I’m your guy. Let’s make forever happen! 🐾 Local adoption fee is $200(in TX) Out of state adoption fee is $450 (includes transport to your area)

Chili Mac

Mastiff

Male, Puppy

St Louis, MO

Size

(when grown) X-Large 101 lbs (46 kg) or more

Details

Good with dogs, House-trained, Spayed or Neutered, Shots are up-to-date,

Story

Meet Chili Mac! This 11-month-old Cane Corso is a big, lovable goofball with a heart as giant as his paws! Chili Mac is equal parts cuddle bug and class clown — he’ll make you laugh one minute and melt into your lap the next. He can be a little shy when meeting new people, but once he decides you’re cool, he’s all in! He’s great with dogs big and small (seriously — from 6 lbs to 120 lbs!), crate and potty trained, and already knows some basic commands. Due to Chili Mac's size and clumsiness, he would do best in a home with older children. He would also be best with someone who has breed/guardian experience given some mouthy behaviors which are normal for the breed. Chili Mac would love an active home with another dog friend or a human adventure buddy. Whether you’re hiking, road-tripping, or just lounging on the couch- as long as you don’t mind a little drool, he’s ready to be your ride-or-die! If interested, please complete the Adoption Application on our website at www.NeedyPaws.org and we will contact you. Adopters must live within an hour’s drive of St. Louis, MO. Our $295 adoption fee includes up-to-date vaccinations, heartworm testing and preventative, spay/neuter and microchip. We are a 100% foster-based rescue and all of our dogs live in approved foster homes. We are dedicated to finding the best Forever Homes, and will perform home visits and conduct veterinarian and reference checks for each potential adopter.

Meet Wendell! 💛 Wendell is a 6-year-old Mastiff mix with a heart as big as his 75-pound frame!

Wendell absolutely aced his temperament test and showed us just how easygoing and wonderful he is.
