Dog Salivary Gland Tumor: What to Know

Salivary glands sit around the mouth, jaw, and upper neck. A tumour may cause a firm or gradually enlarging swelling, trouble chewing or swallowing, drooling, bad breath, facial asymmetry, or reduced movement of the jaw. Some dogs show no clear sign until the swelling is noticed while grooming. Enlarged lymph nodes, infection, a dental problem, or a cyst can look similar. The location, texture, growth pattern, and nearby nerve involvement help guide assessment.

Arrange a veterinary appointment for a new or persistent lump around the mouth, cheek, jaw, or neck. Note its size and position, take regular photographs, and record changes in eating, drinking, drooling, or breathing. The veterinarian may examine the mouth, feel local lymph nodes, and recommend needle sampling, imaging, or a biopsy. If a tumour is confirmed, [Tumour Removal Surgery](/treatments/surgical-oncology/tumour-removal-surgery/) may be considered; [Radiotherapy](/treatments/radiation-oncology/radiotherapy/) can be discussed when surgery is unsuitable or additional local treatment is needed.

Seek urgent veterinary attention if swelling interferes with breathing or swallowing, the dog cannot eat or drink, bleeding does not stop, severe pain develops, or the lump changes quickly. Facial swelling with weakness, collapse, or repeated vomiting also needs immediate assessment.

Ask which gland or nearby structure is involved, whether a sample is needed, how the mass affects swallowing or nerves, and whether imaging should precede surgery. Ask about expected recovery, margins, pain control, and how follow-up will check for local change.
