My dog's face is swollen, he flinches, but seems normal. What's wrong?

Pet's info: Dog | Chihuahua | Male | neutered | 5 years and 11 months old | 11 lbs

I just noticed this evening that my dog has a swollen face. He flinches when I want to touch it. I tried looking in his mouth to see if I could see anything obvious, I couldn’t. I don’t this he has a fever. He’s still wanting to chew on his bone. He seems to be acting normal. Any ideas or suggestions?

In a small dog, my first suspicion would be a tooth-root abscess. Small dogs tend to get rather diseased teeth as they age and are prone to infections like this. The other possibility is that he bumped his face on something. This is over a bony area that can swell with fluid when it hits something hard (i.e. door, chair, etc.). In this case, the swelling will eventually go down within two weeks or so. In order to tell exactly what it is, you'll have to take Teddy to a vet. They can take a sample of the fluid and help to narrow-down the possibilities. I hope that helps and Teddy gets better soon.
