Story

I received the dog in September 2025. I have papers on the dog showing birth, breed, neutered and current shot record. The dog is very timid, does not/will not sleep in a dog bed, and does not take getting shots well. Very good house dog and is house trained. Barks loud! I made my own schedule for taking the dog out daily to pee and poop. I take the dog outside 3 to 4 time daily. Dog does not run!

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.
