Customer Question

My 10 year old dog has been having cyanosis episodes leading to fainting sometimes. Other times he turns pink again without passing out. Seems to happen at times of excitement, exercise intolerance or sleep. He is yawning a lot and has increased snoring and breathing sounds. He has been to neurology (Mri and csf tests negative) cardiology ( Holter monitor, ekg, egg and blood tests..nothing they felt was significant enough to cause this)aside from slightly high red blood cell count all blood tests normal, and now the medicine team looked at him and did ultrasound of abdomen and head area. He did shoe signs of redundant trachea but no tracheal collapse. They didnt feel anything they saw on those tests could cause this either. He continues to have these episodes. Any ideas please help these episodes are so scary. He's my best friend I love him more then most people lol!

Hi there, I'm Dr. Sara. I'm a licensed veterinarian who works exclusively with dogs and cats. I'm sorry that your question has gone so long without any replies. This is likely because we aren't likely to have any new suggestions for you. Most of us are experienced general practitioners who would refer a case like this to a board certified specialist, which you've already done. I'm sure that these episodes are very scary for you and for him, I'm sorry that the specialty hospital hasn't been able to come up with an answer yet. When I have a pet who has mystery symptoms but the diagnostics are all normal, I'm most concerned for cancer. There's no one definitive test for cancer, so it's often something that we put on the table as a diagnosis of exclusion. I'm afraid when the specialists are stumped, by default, we general practitioners are likely stumped as well. I'm sorry that we can't be of more help.
