Cozzi is my 12 year old cockatiel. Over the course of the past month, he has been doing a lot of sneezing, and open beak breathing. He has always been active, but is not playing anymore and he becomes easily exerted. His diet still seems good, and he eats well. Once I noticed him having symptoms of being ill, I immediately took him to the avian vet nearest to me, where they examined him, sedated him, took X-rays, and lab work. Labs all came back good, but the X-rays definitely shows something going on. The vet suspected a fungus in his lungs, and heart disease based on his symptoms of open beak breathing. At first they put him on anti inflammatory pain meds with a fungus antibiotic. It did nothing. They then put him on another antibiotic for infection just to cover the bases. It did nothing. At his next visit they gave him an injection of Furosemide, and we didn't really see much change. They also sent him home with the liquid furosemide which was compounded at a pharmacy. I still didn't see any change with Cozzi, so now they put him on Pimobendan, and still no changes. I am extremely tired, as I am up all hours of the night with my baby trying to comfort him. He just wants to be held against my chest at night...so I do it until I know I'm about to fall asleep, then place him back in his cage. I get back up with him several times in the night hearing him sneezing and crying for me. I am feeling very sad, and wish there was a medication that would help him breathe better. The vet did say they can try something else...but I just wanted to ask if anyone else had any experience in this, and what has helped? I am at a $950 vet bill plus medication costs, but will keep going until he can be comfortable! Thank you to anyone who can help give me some more advice.
