My dog's swollen salivary gland is back and bigger. What should I do?

Updated on September 23rd, 2025

Pet's info: Dog | Chihuahua | Female | spayed | 4 years and 2 months old | 6 lbs

My dog appears to have a swollen salivary gland. I took her to the vet once for it and they told me that it would go away by itself. Now it’s back a year and a half later and it’s bigger this time. I tired opening her mouth to look under her tongue and when I moved her tongue she cried. I’m going to take her to the vet in the morning. She is breathing fine. Is there anything I can do or should do?

I am sorry to hear about Lupita. It sounds like she could have a sialocele or ruptured salivary duct causing accumulation of saliva under the skin. Unfortunately the only recommended treatment for this condition is surgery. You can read more about this condition and its treatment at https://www.acvs.org/small-animal/salivary-mucocele
If your vet isn't comfortable performing the surgery you can ask for referral to a specialist who can perform the procedure.

    Hello, sorry to hear about Lupita. These swellings can become firm and turn into stones which will need to be removed. Your veterinarian will likely recommend this procedure at her next appointment. In the interim, monitor her appetite and make sure she is still able to eat. Hope this helps and best of luck.
