Uremia is defined as an elevated level of blood urea nitrogen above the normal range of 3.1 - 9.2 mmol/L.

There are numerous causes of uremia, including:

Clinical signs of uremia are variable due to the large number of causes, but may anorexia, listlessness, vomiting and diarrhea.

Dogs with renal azotaemia have variable degrees of hypertension and high urinary protein and electrolyte excretions, as well as reduced blood mean corpuscular volume, packed cell volume and increased mean corpuscular hemoglobin concentration[5].

Treatment includes Iv fluid therapy and addressing underlying disease cause(s).
