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 than the circumstances were facing. 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!! He does so well at dogs parks, we take him almost every day. 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 & say hi its fine. I would love to be able to visit him occasionally. But he does need more than I can provide at this point so this must be done. You will love every second with him. He keeps life interesting thats for sure. He needs someone with time & energy.

Story
Waldo is the kind of dog who reminds you that some of the very best relationships are worth taking your time. While the world can feel a little overwhelming to him at first, beneath that cautious exterior is an affectionate, goofy boy with so much love to give. Once Waldo feels safe, his personality begins to shine. He'll happily lean into you for comfort, rest his head—and sometimes even his paws—in your lap, and show off his playful, puppy-like side. He enjoys the quieter pace of life, making him a wonderful companion for someone who appreciates life's simple moments. Waldo thrives when he's given the opportunity to settle in at his own pace. As his confidence grows, so does his personality—and the bond you'll build together is incredibly rewarding. He'll be happiest in a calm, low-traffic home with adults who will continue helping him build confidence through patience, consistency, and kindness. Waldo has also found comfort in the company of larger dogs and may enjoy having a confident canine companion to help show him the ropes. If you're looking for a loyal companion and believe that the best friendships are built on trust, patience, and understanding, Waldo just might be the perfect match. If you are interested in Waldo, please give us a call at (401) 846-8276. For more information about our adoption process, please visit www.potterleague.org.

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
Brutus's Story Brutus There’s no pre-heating needed to get this guy to warm up to you! Brutus has a sweet disposition and is friendly and affectionate with people right from the start. He’s easygoing, too – 30 minutes after we met him, he curled up and relaxed on the floor while the humans chatted around him. Rescued after being abandoned behind a restaurant, Brutus is estimated to be two to four years old. He is a good-size boy, weighing about 60 pounds, but is gentle and aware of his size. He takes well to being handled and groomed with a brush. Brutus walks nicely on leash and seems to be good around other dogs, showing interest and keeping calm. We’ll learn and share more as we get to know him better. Better yet, please reach out to us and come meet this sweet boy for yourself! For more information email me at hdrmarktomasko@gmail.com To apply to adopt Brutus please go to handsomedansrescue.org
