The most common identified primary diseases were kidney disease (30% of dogs, 52% of cats) and hepatobiliary disease in dogs (19%) and lower urinary tract disease in cats (30%). Hypoadrenocorticism was uncommon, occurring in 2% of dogs. Urinary tract disease and low effective circulating volume were the most commonly identified underlying pathophysiologic mechanisms. The median (25th\u201375th percentile) blood Na:K ratio for all dogs was 25.6 (range: 24.3\u201326.4) and for cats was 23.4 (range: 19.1\u201325.8). Severe hyperkalemia (&gt;7.0\u00a0mmol\/L) was evident in 21 of 711 (3%) dogs and 50 of 159 (31%) cats. Severe hyponatremia (&lt;130\u00a0mmol\/L) was evident in 28 of 711 (4%) dogs and six of 159 (4%) cats.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The prevalence of a low blood Na:K ratio in dogs was higher than previously reported, and this finding cannot be assumed to be due to hypoadrenocorticism.
