Adopting a senior dog has many benefits compared to getting a puppy. Older dogs are often already trained, calmer, and more content. They have typically been around humans and can be easier to integrate into a household. They require less exercise and time commitment compared to puppies. Senior dogs also have a known personality and history, making it easier to find a good match. Additionally, adoption fees for older dogs are often discounted, and adopting them helps reduce the number of dogs waiting for homes.
