Aegean

Aegean trails at #2 with a dog-friendliness score of 4 and a shorter lifespan of 9 to 12 years. This Greek breed offers a mildly energetic companion but falls behind the Kurilian by up to 11 years in longevity. With a typical activity level 30% higher than the average cat, Aegeans suit active homes, though families trading lifespan should note a 3-year gap versus #3 American Bobtail.
