Story
Hi there, I'm Denver! I'm 2 years young and full of life, always ready to play fetch or chase a squirrel. I'm super friendly, I've never met a person I didn't like. My energy is infectious, and I love to share it with everyone around me. I'm strong too, which makes me a great partner for long walks or hikes. I'm not just all fun and games though. I'm also very affectionate, always ready to give a friendly paw or a comforting nuzzle. I'm looking for a forever home where I can share all this love and energy. Adopting me means gaining a loyal friend who will always be there to brighten your day. I promise, life is never dull with me around! Meet me at the shelter or fill an application today! I'm so ready to gain a forever home.

Story
Diesel is 13 months old . He has a very sweet temperament . He is a large , young dog so a house with other dogs or an active owner he can play with is best . He still has no idea how big he is (still growing even ) and wants to cuddle . He’s a good car rider . Everyone that meets his loves him . The only issue he has is that he is a very big puppy ! He went through 6 weeks of training at Delmarva K9 so he knows basic commands Sit , stay … ect …. I am simply rehoming him because family circumstances have changed unexpectedly and I have to take on a second job and it will not be fair for such a young dog to be home alone for 14 hours a day . He does well in a run . Vet references a plus !!!! He’s a great dog .. so I want him to have a great home !!
