The life expectancy of a Pomeranian is 12 to 16 years.[13][better source needed] A well-bred dog on a good diet with appropriate exercise will have few health problems; and, if kept trim and fit, a Pomeranian is a sturdy dog.[14] The breed does have similar health issues to many dog breeds, although some issues such as hip dysplasia are uncommon because of the Pomeranian's lightweight build.[15] Some health issues can develop as a result of lack of attention to grooming and teeth-, ear-, and eye-cleaning.
