There is currently 1 adoptable senior Unknown Breed dog (age 7 and up) in Colorado, each from a local shelter or rescue. Older Unknown Breeds are often passed over for puppies, yet they're usually house-trained, settled in temperament, and ready to bond right away — and because they're fully grown, you already know their size and personality. Adopting a senior Unknown Breed in Colorado means welcoming a calm, grateful companion who can settle in from day one.
