Adopting a senior dog in Colorado — FAQ

What counts as a senior dog?

Most shelters and vets consider a dog "senior" around age 7, though large breeds often age sooner and small breeds a little later. Every dog listed here is 7 years or older.

How do I adopt a senior dog in Colorado?

Open any dog's profile to see which shelter or rescue is caring for them, then use the adoption link or contact details to apply directly with that organization. Lily's Second Chance gathers senior dogs in one place so they're easier to find — the adoption itself happens through the local group.

How much does it cost to adopt a senior dog in Colorado?

Adoption fees vary by organization, but senior dogs are frequently discounted or sponsored because they wait the longest. Many rescues also begin any needed medical care before adoption. The dog's profile or the shelter can confirm the current fee.

Are senior dogs harder to care for?

Usually not. Older dogs are typically calmer and already trained, which makes the first weeks far easier than with a puppy. Some have age-related needs like a special diet or joint support, and the listing or shelter will tell you what to expect.

Can I adopt a senior dog from another city in Colorado?

Yes. Most shelters and rescues in Colorado welcome adopters from anywhere in the state, and some can arrange transport within Colorado for the right match. Open a dog's profile to see the organization's contact details and ask them directly how their process works.

What should I expect in the first weeks after adopting a senior dog in Colorado?

Senior dogs usually settle in faster than puppies because they're already past the most demanding stage. Expect a brief adjustment period — they may be shy at first, then relax into their personality. A consistent routine, a comfortable spot to rest, and patience are usually all it takes.

Can I foster a senior dog in Colorado instead of adopting?

Many shelters and rescues in Colorado offer foster programs — sometimes with a foster-to-adopt path so you can try the match before committing. Fostering is especially valuable for senior dogs because it gets them out of a kennel and into a calm home while they wait for their forever family. Ask the organization on any dog's profile whether fostering is available.

Are senior dogs good with children or other pets in a Colorado home?

Many senior dogs are calm, gentle, and well-suited to family life — but it depends on the individual dog more than anything else. The shelter or rescue caring for each dog can tell you their specific history with children, cats, and other dogs before you apply. Many organizations offer meet-and-greets to make sure the match is right for everyone.

Know a senior dog in Colorado who needs a home?

Shelters and rescues can list adoptable senior dogs for free.
