My dog had surgery. What are signs of complications or infection?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | neutered | 5 years old | 21 lbs

My dog had a foreign body removed 6 days ago and I’m very nervous about him having dehiscence and developing peritonitis. He seems sore and his back is slightly arched, but his appetite is very good and he hasn’t vomited. He trembles if he overexerts himself/overeats, but I think that’s because his meds are insufficient (vet won’t change it). If he were having such a complication, would there be more obvious signs? At what point after surgery is an animal out of the woods for this?

Typically with dehiscence, they will be lethargic, not eating, have a fever (over 103) and just not themselves. While it takes time to recover from a surgery like this I would recommend having your veterinarian just examine Patton. I rather be safe then sorry, especially if you are concerned with his behavior at home. It may be normal for him post surgery but it may also be that he is very stoic and there is more going on. As a veterinarian I rather my clients bring the animals in to get looked at and it be nothing then wait it out and it be serious. Thank you for using Petco Pet Education Center, formerly Petcoach and I hope Patton feels better soon.
