Our 12 yr.old female ShiTzu, 16 lbs. has a congestive
heart condition,
and a restricted esophagus. She currently takes 1 Enalapril Maleate, 5 mg., Temaril-P 1/2 tab., 2X daily, and Previcox, 1/2 57mg. pill 2X day for arthritis. Would adding an anti-histamine like chlortrimeton or benedryl help ease her cough and congestion?
