Why is my dog's face swollen with a hard bump, no visible wound?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Large (61lb +) | Male | neutered | 6 years and 7 months old | 95 lbs

This morning I noticed the left side of Diesel's face is swollen. No visible wound. It feels like a hard bump just above his upper jaw and under his eye. He had a dog play date yesterday, but like I said, no visible wound. It doesn't seem to bother him except he hasn't eaten as much as he normally does in the last 24hrs.

Thanks for using Petco Pet Education Center, formerly Petcoach! He is so adorable! This could have been due to a traumatic injury during the play date even if there is not an external wound present. Another possibility is that this was noted incidentally after a play date and this is actually something unrelated such as due to dental disease or even a growth underneath those tissues. I recommend you keep an eye on it for now. If it is just swelling from a traumatic injury, it may improve on its own. However, it may not improve on its own and need further therapy. If it is something else, it will probably continue to be present or worsen over time. If it does not improve or it worsens in the next week, I highly recommend that you have him evaluated by a veterinarian for further assessment and treatment. Good luck!
