So, I am currently looking for a home with a dog or a cat or not any other animals is fine too. Do you think I could be a match? Come visit me anytime we are open!

Chili Mac

Mastiff

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.

Story

🩷I learned much about adorable Meryl Streep yesterday as we buddied up and attended CARE’S Adoption Event at “Tower Grove Pride” event. This adorable one and a half year-old pup showed her happy self from the moment she jumped in the car and was the perfect backseat rider. 🩷As we walked to CARE’S tent Meryl walked well on the leash. The event was well attended and this sweet pup was friendly and sweet throughout. As participants of all ages came up to say “Hi” and gave her pets she was gentle to everyone. As other dogs passed she was mostly indifferent being content and enjoying the moment. When this precious girl was tired she laid down and fell fast asleep and stayed like that as the action continued all around her. After her short nap we headed back to the car. This precious, perfect girl made the day’s event fun, happy and totally enjoyable for me her sidekick💕 🩷All I could think is this fabulous pup belongs in a loving home and hopefully soon! Meryl Streep, is a treasure and would be a cherished pup for many families. -Her eye condition is called Cherry Eye and is not serious and will be taken care of by CARES clinic when she’s adopted. 🩷She is at CARE STL for you to meet and possibly fall in love just like me🩷🐾XOXO

Bagels

Mastiff Mixed Breed (Medium)

Female, 1 yr 3 mos

St. Louis, MO

Size

(when grown) Med. 26-60 lbs (12-27 kg)

Details

Good with dogs, House-trained, Spayed or Neutered,

Story

Bagels is an adorable 11-month-old Mastiff mix (we suspect there's a little Boxer in her!) who is the very definition of a tiny lap puppy disguised in a big, beautiful body. This goofy girl has absolutely no clue how big she is, and she'll try to climb right onto your lap to melt you with her big brown eyes and sweet face! Bagels is a true Velcro pup who will follow you everywhere, convinced that your personal space is her personal cuddle zone. But with a face this cute, who needs personal space? She's quite smart, too, and is great motivated, which means she's quick to follow commands. Bagels is reliably house-broken (for the most part!) and loves sleeping comfortably on her own couch, going for walks around the neighborhood, and goofing around in the backyard. She's ready to fill an active home with love, snuggles, and endless laughs!
