Story
Silvio is the best boy. He is so loving, loves cuddles... and any kind of attention. He thinks hes small - still has puppy energy. He turned 3 in January 2026. I have no complaints with him whatsoever... rehoming him breaks our hearts, but he deserves better. He needs room to stretch his legs and exercise on a regular basis. He loves playing in snow, he is so funny when he gets the zoomies lol. He is just the best!! Gentle giant but protective over his family. He's not the biggest fan of strangers getting too close to us or our home but once they let him sniff them & say hi its fine. I would love to be able to visit him occasionally. But he does need more than I can provide so this must be done. You will love every second with him. He keeps lofe interesting thats for sure. He needs someone with time & energy.

Story
My neighbor inherited his mother’s dogs after she passed away. They are a bonded pair. Unfortunately the landlord won’t let them stay for much longer. We’ve tried most avenues and are doing our best to keep them out of the shelter. Both dogs are house trained, walk on leashes well, have never bit anyone (including vets), and love tuff chew toys or tug of war! They are the best super sweet and loving, a little over weight as they lived with a 80 year old woman who fed them with love and couldn’t really walk far. Rosie: 11y/o Mastiff mix Dingo: 6 y/o Blue Heeler Both dogs love being outside and are fairly quiet. Dingo will bark to alert for people at the door but it’s very minimal. They are great with kids and live with cats!

Story
To adopt please fill out an adoption application. Be sure to watch his video!  Reggie is a 6yo male Mastiff/German Shepherd mix who was rescued as a stray in Memphis. Friendly and well-socialized. Reggie is selective about his dog friends and would probably enjoy being the only dog.  Not cat tested.  History with children unknown. Medium energy level outside, quiet and well-mannered in the house.  Crate trained and housebroken. Obeys basic commands.  Loves to be with his people.  Good on a leash, rides great in the car.  When he first came to us, Reggie had heartworms, but he was treated without complications and cured and is now ready for adoption. Healthy and fully vetted, current on shots, neutered, weighs about 85 pounds.  AWESOME mastiff/shepherd mix will make a wonderful companion (and jogging partner!)  for an active family who loves the breed. .

Story
Cooper is a cuddly boy who just wants to snuggle and play with his toys. He is 6 years old. He is a funny and loyal pup who wants to be with the love of his life. Unfortunately, he does not get along with our male dog and would be best as an only dog. It breaks our hearts to rehome him, but he deserves what is best for him. He loves children & due to his size (60lbs) and goofiness,we recommend older children. If you need a best friend then he is your guy.

Story
Hello there, I'm Mark! I may be young, but I've got a heart full of love to give. Every morning, I wake up excited for the day ahead. I love playing with my favorite chew toy, but what I really crave is a good game of fetch with a human friend. I'm a quick learner, too! I've already mastered 'sit' and 'stay', and I'm eager to learn more. I promise to be your loyal companion, always ready for an adventure or a cozy nap on the couch. I'm not just looking for a home, I'm looking for a family. Adopt me and let's create a lifetime of wonderful memories together.

Story
*Special Needs*Meet Leo, a giant sweetheart with a sensitive side who is looking for a very understanding home. This handsome Saint Bernard has special medical and behavioral needs and is available to meet by appointment only. If you are interested in adopting/meeting Leo, please email dogs@worcesterarl.org. Leo can be uncomfortable meeting new people, especially when people stare at him or lean over him too quickly. He does best with calm, respectful introductions and requires an adult home that can understand and honor his boundaries while he settles in. Building trust with Leo is incredibly rewarding, and once you are part of his circle, he becomes a loving, affectionate, goofy companion who enjoys being close to his people. Leo is looking to live as the only dog in the home. Leo is searching for adopters who appreciate that large dogs can have big feelings too. He will need a home committed to providing structure, patience, and continued support for his needs. In return, Leo has so much love, loyalty, and personality to share with the people willing to give him the chance he deserves. He is such a lovely dog, and just needs to find the right home. If you are interested in adopting Leo, please email dogs@worcesterarl.org.
