Right now, though, I still think naps are the greatest invention ever. I'm growing bigger every day and will be ready for my forever home at the end of August, so you can put in your application now and the amazing team will be in contact soon!

Story
Hi, I'm Daniel! I'm the biggest puppy in the litter, and I've been told I look like a fuzzy little squirrel. I take that as a compliment! My eyes are open, and while I do practice walking now and then, I'm much more interested in perfecting my favorite skill: sleeping belly-up without a care in the world. I'll be ready for my forever family at the end of August, and I'm accepting applications now! We do not see Adopt-a-Pet inquiries!

Hi, I'm Suzy Q! I'm the smallest brown girl in the litter, but I make sure everyone knows I'm here. My eyes are open, I'm already toddling around, and I've recently discovered something incredible... baby barks!

Story
Cora is a wiggle worm that loves to lean herself into you. She came in with a dog her size and showed a little discomfort meeting a new dog slightly smaller then her so slow gradual introductions will be important. Since Cora was a stray, it is unknown how she does with children and other animals. She is known to submissive grin!

Story
Meet Zeus! This big, playful boy might need a little time to warm up, but once he does, his goofy personality really shines. He's looking for a patient home that will give him the chance to settle in and feel comfortable. Once he opens up, he's all about fun, attention, and making you laugh. Volunteers can't help but gush about him - he's a fun, easy dog to walk, happily taking his time to stop and sniff his favorite spots. He responds to his name, sits when asked, and takes treats with gentle manners. During quiet moments he leans in for soft, reassuring petting, and when the toys come out, his playful side shines!Zeus will only be rehomed to a family without children or with kids at least 10 years of age and without cats, and if considered for a multi-animal home, family must be skilled in managing food resources to mitigate guarding behavior between household dogs. Primary Color: Red Brown Secondary Color: White Weight: 113.2 Age: 1yrs 7mths 0wks
