Why is my senior dog snoring more and vomiting daily? What's wrong?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Large (61lb +) | Female | spayed | 11 years and 4 months old | 85 lbs

Our 12 year old Lab/Irish setter has been snoring for a while now. It seems to have gotten worse and now she is vomiting almost daily. Sometimes it is undigested food, other times a frothy slime.

Hello, thank you for using Petco Pet Education Center, formerly Petcoach.

My suggestion right off the bat, is to take Lilly to your veterinarian for an exam. Any persistent or worsening symptoms should be considered serious especially in an older dog.

Unfortunately her symptoms do not point to one specific illness or disease process so it is really difficult to speculate as to what may be going on with her. What I can tell you is that snoring often points to a space occupying lesion (tumor, polyp or foreign body) somewhere in the upper airway. This obstruction can trigger vomiting in some instances although the vomiting may or may not be directly related to the snoring.

I suggest you take Lilly to your veterinarian as soon as possible for an examination. Likely some diagnostic testing will be needed to get a diagnosis.

Hope this helps. Best wishes.
