My maltese always had a weak trachea. Cough a little after water but when she got 8 she coughed more. Found out her heart was enlarged and pressing on her trachea which made her cough because it was weak in the first place. She went on cough medicine and prednisone that did help the cough a little. YOu might want to get his heart checked to see if it is okay. Sometimes dogs cough too when they have a bad heart. Also she was overweight so we put her on a diet which helped too. |
