1 Introduction Thromboelastography (TEG) provides a global assessment of hemostasis from clot initiation to dissolution and identifies patients with both hemorrhagic and thrombotic tendencies. Thromboelastography has been used to identify hemostatic derangements associated with several disease states in dogs, including hyperadrenocorticism, chronic hepatopathy, protein-losing nephropathy, acute pancreatitis, and trauma [1-5]. The assay can be used to guide therapeutic decisions as well [6].
