Why is my senior dog breathing fast while sleeping? Should I worry?

Pet's info: Dog | English Setter | Male | neutered | 10 years old | 75 lbs

Hi, I’m babysitting my friends 10 year old English setter, he’s sleeping right now and breathing quite fast 66-68 breaths per minute. Besides that he’s sleeping comfortably and doesn’t seem to be in pain. Should I be worried?

It is possible that he has an underlying heart condition if his breathing continues for consecutive days in a row at this rate. I would recommend alerting his owners of this abnormal breathing so that they are informed. They may have already witnessed this themselves or may even be aware of a condition he has already. However, you are right to inquire about this, because breathing rates <30 breaths per minute while in a deep sleep are considered abnormal and the #1 cause of this is an underlying heart condition and potentially heart failure. Best of luck with Cody and informing the owners of your concerns for his overall health and well-being.
