Hello, my name is***** and I have over 20 years of experience as a veterinarian. I understand that your pup has fatty tumors which seem to be getting larger over time and you are wondering how concerned you need to be.

Were these masses actually aspirated or biopsied to determine that they are indeed fat tumors (lipomas)?

There are other types of connective tissue tumors that can feel like a lipoma. These can be soft tissue sarcomas or mesenchymal cell tumors. While these tumors don't spread to other sites they can be very locally invasive and extend deep into surrounding tissues which can make complete removal very difficult if they are allowed to get sizable.

If your pup truly has lipomas then even if they get big if they don't interfere with getting around or function then we don't need to be overly concerned about them. But if they are in area that will interfere with getting around comfortably (axillary area or armpit, or groin) then I do recommend removal if they seem to be increasing in size.

If these lumps haven't been aspirated or biopsied to determine more definitively what sort of mass they are, and we are relying on location and the way they feel then I would not feel comfortable if they are getting bigger, especially if they are in a spot that will eventually create problems. I would want a biopsy before being comfortable not having them removed.

Please let me know if you have any further questions.
