| **'''Sodium Bicarbonate:''' Ethylene Glycol is a weak acid. Therefore in order to increase the rate of renal clearance sodium bicarbonate can be administered to dogs. Intravenous administration of sodium bicarbonate at a concentration of 1-2 mmol/kg every 3 to 6 hours achieves sufficient alkalinisation of the urine.<ref>'''Canine Medicine and Therapeutics''' (Fourth Edition, 1998),''Blackwell Science'', p1049 </ref>.
