The Dog. A Maltese her name was Daisy and she was 14 years old. She was on 4-5 pill medications, the highest dosage. 1-2 liquid medications. For the past year or more she had been having coughing breathing issues. That was due to a collapsed trachea. the heart had grown so much it was pushing against the trachea. She did well with medication, coughing occasionally. Over time we took her for visits and I think the heart grew more. Taking up most of body. They also said she had a tumor. But because of age and health issues, best not to do anything. Recently over past weeks more breathing issues occurred. She would sit and put head at angle while breathing. Then this past Friday or Saturday she fell down standing on the ground and made a screeching noise in a puddle of pee. Over previous weeks she had couple screaming episodes while pooping.. But after Fri- sat she was different. With glazed look in her eyes, hearing didn't seem good and heavy labored breathing.overall a very disinterested dog. But during whole time she would eat her dinner, drink water and use puppy pads or go outside. She didn't eat puperoni as much though. Last night I gave her dinner and she came to eat after her coughing and breathing issues. Then this morning I woke up and she was in kitchen all by herself just sitting there breathing and panting very heavy. So I brought her into my room and she did this for a couple hours. She slowly walked outside to go to the restroom. But stayed there afterwards. I went to look at the tonghue and it was white and gums didn't look good. We took her to the vet and he said there was fluid in the lungs and he could only hear small area in lungs getting air. He said they could try something but it was 50/50 it would work. So we decided to give her peace. She was always a fighter. But struggling. Very sad we let her go. Questioning my decision. She ate dinner the night before and night before and continued to pee outside or on puppy pads. Even after falling and screaming incident. Please give me your thoughts. Thank you for your time. Did I do wrong? Did we let go to early?
