Story
Koda is a spunky and energetic male dog with a lot of love to give once he warms up to you. He can be a little nervous around new people at first, but with time and patience, he’ll show his playful and affectionate side. Koda is a big fan of treats and is eager to learn, though he doesn’t know any commands yet—he’d benefit from some training and consistency. He does need some work on his leash manners but is ready to improve. Koda enjoys playing with toys, and just about any toy will do. Due to his energy and need for structure, he would do best with an experienced dog owner in a home without tiny humans, where he can get the attention and training he deserves.
