Sunset Shimmer was about 13 or 14 when she was Princess Celestia's student. When she ran off into the human world, she was roughly about the same age as a freshman in high school. By the time Twilight got there for the first time, Sunset was about the same age as a high school senior, 16-17. Also when Sci-Twi, Sunset, and Rainbow Dash, all 16-17 years old in human years, stumble across a portal that leads to Equestria, they come out as ponies who are around the same age group as their counterparts. I think the producers of the show meant to imply that the lifespan of a pony is about the same as a human, 70-80 years or more, and that they age at a normal human rate. So while ponies in our world would live 20-30 years, they would live a full human life in Equestria. As for animals like Applejack's dog and Rarity's cat, they look just like our own pets in this world, so we naturally assume they age at the same rate of a normal animal of their species.
