Dalteparin (Fragmin) is a low-molecular weight heparin used primarily for various causes of thromboembolism in dogs[1].

Administration of this drug in dogs results in progressive hypocoagulability as determined by coagulation assays, characterized by prolonged prothrombin and activated partial thromboplastin time.

Although activated clotting time and clot rates may become prolonged, platelet function parameters are usually unaffected[2].

Its effectiveness at prevent thromboembolism is still debatable[3] compared with efficacy of other drugs such as low-dose aspirin or clopidogrel.

Recommended dose rate is 25 - 175 U/kg given subcutaneously every 12 hours[4].
