Story

How this pet arrived: Shout was brought in by a community member on February 27, 2026. Why this pet is the one for you: Playful and fun-loving, Shout's silly antics will provide endless entertainment. She approaches life with wide-eyed curiosity and pure enthusiasm, making every day an adventure. Whether she's exploring a new toy, bouncing around the yard, or zooming through the house, her excitement about the world lasts all day long (until naptime, of course)! With boundless energy and a whole lot of charisma, Shout absolutely loves to play. She's still learning how to walk on a leash and would thrive with a patient family ready to guide her as she grows. What she's most excited about, though, is finding a home where she can share all her love, cuddles, and puppy kisses. At SDHS: Shout has been vaccinated, microchipped and spayed. She is now ready for adoption! Primary Color: Black Secondary Color: White Weight: 22.4 Age: 0yrs 4mths 0wks
