Dog Mammary Tumor Removal Surgery
📝 Summary
Dog mammary tumors are common (especially unspayed, rising with age); remove early and submit tissue for pathology. Anesthesia: intubation + inhalation or injection, dog supine. Four techniques by site/lymph flow: single gland, regional, unilateral chain (effective), bilateral (malignant, may need skin graft).
1 Why and How
Canine mammary tumors are frequent, especially without ovariohysterectomy, and more common with age. Find and operate early; send all removed tissue for histopathology. Anesthesia uses an endotracheal tube with inhalation or standard injection, with the dog in dorsal recumbency.
2 Four Techniques
The method depends on the dog’s state, the gland involved, and lymph flow: (1) single gland—remove just the gland, or the gland with its skin; (2) regional—several diseased glands or one lymphatic chain; (3) unilateral chain—the whole one side, a very effective approach; (4) bilateral—all glands, for wide or malignant disease, often needing skin reconstruction.
