Cloned Dog Life Expectancy. Therefore, we should be able to finally answer the question of whether at least some cloned animals can reach a life expectancy similar to that of the control animals. A dog may live a few years longer or shorter than the average life expectancy mentioned in the table.
From the preceding table, you can get a fair idea of the average life expectancy of dogs by breed. The top 25 that we include here are from the akc’s recent list. This is a gift that gives back each day.
