Nederlandse Kooikerhondje Health Guide

Back to Nederlandse Kooikerhondje Overview

Understanding the health profile of the Nederlandse Kooikerhondje helps owners make informed decisions about screening, insurance, and preventive care. Like many pedigree breeds, the Nederlandse Kooikerhondje is prone to certain hereditary and acquired health conditions, most notably Polymyositis and Epilepsy. Lifespan varies considerably — from 12 to 15 years — and is strongly influenced by diet, weight management, and early veterinary screening. Smaller breeds often enjoy longer lifespans but can be prone to dental disease and patellar luxation; regular dental care and weight monitoring are particularly important.
