Puppy breathing fast and slow after spay surgery, should I worry?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Female | spayed | 5 months and 23 days old | 10.6 lbs

My puppy was spayed today. As she's sleeping I'm noticing her breathing goes back and forth between fast and slow. I know that she did this after two of her vaccinations before because they were the most painful for her. So is it something I should be concerned with? Or just keep an eye out? She's only been home for a few hours. She was able to eat a little bit and drink some sips of water.

Breathing at an erratic rate while asleep may simply be an indication of active dreaming. As long as her breathing does not appear labored and as long as she is not having any other indications of illness, I would not worry too much about her health. Continue to monitor for any significant changes to her health, monitor her surgical site for any signs of infection or discharge (serous / clear discharge in small amounts is normal), and keep a close eye on her energy level. If all of these seem to check out, I don't think you have anything to be concerned about at this time.
