Which age group is most likely to present with ectopic ureters?

Ectopic ureters are congenital anomalies where the ureters do not connect normally to the bladder, often resulting in urinary incontinence. This condition is most commonly seen in young animals, particularly cats and puppies under the age of 6 months.

In this age group, the anatomical development is still in progress, and any abnormalities can lead to this condition being recognized early in life. Young cats and puppies are more susceptible due to the immaturity of their urinary system, making it more likely for diagnostic evaluations to reveal such anomalies during routine exams or when issues arise.

Older adults or middle-aged dogs may experience urinary issues, but these are typically related to other causes such as age-related conditions, infections, or complications of other diseases rather than congenital abnormalities. Adolescents may also present with urinary symptoms due to different issues altogether, but ectopic ureters are not commonly associated with this age group. Therefore, young animals under 6 months old are the demographic most likely affected by ectopic ureters, aligning with the correct answer provided.
