Bad Smell Coming From a Large Mast Cell Tumor
by Julie
(Garner, NC)
Reader Question
Our dog has a very large lump, about the size of a grapefruit on her left hind leg. It is untreatable as we found out in the biopsy but will not metastasize (sp?). There is a very foul odor coming from the lump, almost like dead fish or something like it. Is there anything we can do about it? Any remedies to help relieve her licking at it? Other than the smell, she is acting normal, appetite good, happy, etc.
Answer from Our Team
A foul smell from a large tumor usually means the surface has broken down or become infected. That can be uncomfortable and needs your vet's attention. They may prescribe antibiotics, recommend gentle cleaning, and suggest pain relief.
To stop licking, use a cone (Elizabethan collar) or a soft recovery collar, or a light, breathable cover your vet recommends. Ask your vet whether palliative options, such as radiation or medicines suited to her tumor, could make her more comfortable. If the lump starts bleeding, or she becomes quiet, stops eating or seems unwell, see your vet promptly. It's good to hear she's still happy and eating.
This is general information, not a diagnosis. Please follow your own vet's advice.
