Before Tumor Surgery: Questions That Protect the First Operation

Owners whose dog is scheduled for biopsy or tumor-removal surgery, especially for a first operation on a mass that may require planned margins.

Define the operation's goal, complete decision-changing diagnostics, agree on pathology handling and prepare a realistic anesthesia and recovery plan before consent.

Confirm fasting and morning-medication instructions in writing. Tell the team about every prescription, NSAID, steroid, anticoagulant, herb and supplement. Share previous anesthesia reactions and new illness. Prepare a nonslip, stair-free recovery area and appropriate restraint or transport help.

1. Ask whether the diagnosis is adequate for surgical planning.
2. Clarify the goal: incisional biopsy, complete excision, debulking or palliation.
3. Review the proposed margins and expected functional or cosmetic change.
4. Ask which imaging or staging result could alter the operation.
5. Confirm specimen orientation, labels, histopathology and how results will be communicated.
6. Review pain control, incision protection, activity limits and emergency coverage.

Before surgery report cough, vomiting, diarrhea, appetite loss, medication error, new bleeding or rapid mass change. After surgery use the separate recovery checklist for pain, incision, eating, elimination and function.

Call before arrival if fasting instructions were not followed, medication was given incorrectly or the dog becomes ill. Seek urgent care for uncontrolled tumor bleeding, collapse, severe breathing difficulty or major trauma to a fragile mass.
