The idea that an adult dog is somehow “damaged goods” as an adoption prospect is strangely widespread, especially among people for whom an older dog would be perfect: novices without the time or experience to raise a puppy in an appropriate way. Adult dogs 5 years old and above are particularly recommended, as many dogs have prolonged adolescence that can be avoided by choosing a dog that is often overlooked in the shelter. Many older dogs still have years of love and deserve an opportunity.
The older dog can easily slip into your life and join the same safety as the dog you brought home as a puppy. And older dogs are everywhere, available in private homes, rescue groups and shelters.
If you are interested in a breed, a rescue group specializing in your breed could be the agreement of the century: these volunteer organizations usually offer their dogs for the cost of vaccines and castration they have already attended.
While the older dog can be a wonderful discovery, you still need to be selective. While it is reasonable for you to work on some things as your new dog gets used to you, you should avoid animals that have too many problems, especially if one of them is aggression. It is highly recommended to work with shelters or rescue groups that evaluate dogs and provide basic training, as well as enroll the new dog in a training course to help you in difficult times.
