He is a sweet and initially a little shy lab mix. He is waiting for heartworm treatment but would do best to complete his treatment in his forever home so he can start bonding to his family. He will require a quiet environment and leashed walks for 6 weeks. He will need a home with another confident dog who can help him adjust to how wonderful life in Colorado can be!
UPDATE- Sumner has had his heartworm treatment and is ready for his forever home.
