What causes a dog's lip lump when they stop eating normally?

Updated on September 23rd, 2025

Pet's info: Dog | Cocker Spaniel | Female | spayed | 4 years and 6 months old

There is a lump on my 4 year old cocker spaniels top lip that doesn’t seem to bother her that much and has been there a while, I am just wondering what it could be as she has stopped eating normally over the last week or so.

This kind of lump/growth needs to be ideally assessed by your veterinarian to have a definitive and specific answer. Usually there are two ways your vet can do that a part from examining it directly during physical examination. A biopsy can be taken under local or general anesthetic, otherwise a smaller sample through a fine needle can be aspirated (this technique is called FNA= fine needle aspiration).
Differentials include skin cysts, infections, benign or more sinister type of tumors.
Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.
