Story
Adam is an 80-pound silly, calm and cuddly boy doing so well with his amazing\ foster who says her favorite qualities are his squishy, loveable face, his soft fur, and his smile. Adam walks well on leash and is eager to "sit" for his dinner. He gets along great with other dogs. He is calm, playful and has good manners and is not overly curious about cats. He is low energy but really enjoys going for walks and being let out to run and explore in a fenced area. Adam is protective of his family and property and, with proper introductions, is the most loyal and gentle guy! He needs an adopter who can guide him with boundaries and offer lots of socialization opportunities. Everyone who meets Adam falls in love with him! He's just waiting for the right one who's ready to provide him a stable and loving home. If that's you, please submit an application and a volunteer will be in touch! (HD)
