Dog's face thinning, vet says rare. Should I get a second opinion?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | spayed | 3 years and 8 months old | 58 lbs

Over the past few weeks my dogs (kia) face has looked thinner. We took her to the vet today for an annual health check and the vet said not to worry, it's rare, just keep an eye on it. Kia doesn't have any other symptoms, she is eating, drinking, toileting and playing as usual. I researched this and I am worried that something else may be happening, please advise.

It is possible that something else could be happening that is causing her face to look thinner, but without seeing Kia in person, I can't say for certain. There is an autoimmune disease called masticatory muscle myositis in which the muscles of the face atrophy causing a thinner looking face and eventually pain while eating. I would bring Kia into another vet for a second opinion, as if she did have masticatory muscle myositis she would need steroids to treat it.
