Aim: A retrospective study was undertaken to determine the occurrence, and the distribution of the most common clinical conditions of young dogs encountered at the National School of Veterinary Medicine clinic, Tunisia, from September 2012 to July 2013, based on sex, age, breeds, and season variation.

Materials and Methods: A total of 515 cases were examined, and 11 clinical conditions were recorded. Clinical examination was performed. X-ray examination and necropsy were carried out only when needed.

Results: Of the 515, 298 cases (57.86%) were male, while 217 (42.14%) were female. The breed-wise difference in the occurrence of various health problems was statistically significant. Nevertheless, no significant association was found between the occurrence of a disease and age. The commonly found clinical conditions were traumatic injuries (22.72%), ectoparasitic infections (20.58%), and gastroenteritis (13.40%). The occurrence of diseases was the highest (60.19%) in the wet season (September-February) followed by 39.81% in the dry season (March-July).

Conclusion: The current study presents the first recorded data about the major clinical conditions of young dogs in Tunisia. These findings can be used to develop more effective disease management and control strategies.
