Neutropenia and Fever During Chemotherapy: Build the Action Plan

Families whose dog receives chemotherapy that can suppress neutrophils and who need a written laboratory and after-hours fever plan.

Know the expected risk window, the prescribed blood-count schedule, how to measure temperature only if trained, and where to go when fever and illness suggest possible infection.

Ask which medicine can lower neutrophils, when the clinic expects the lowest count, and when CBC testing is scheduled. Have the team demonstrate temperature measurement if they want it done at home; never force a distressed dog. Identify an emergency hospital that can contact the oncology service. If instructions conflict, pause and ask the treating clinic to reconcile them; do not choose the instruction that seems easiest.

1. Write treatment dates and the clinic-specific risk window on one calendar.
2. Book every CBC before leaving the oncology visit and record who reviews it.
3. Observe appetite, energy, vomiting, diarrhea, breathing, urinary signs, wounds, and infection exposure.
4. Use only the temperature method and threshold supplied by the clinic.
5. If fever or marked illness occurs, call ahead and state the chemotherapy medicine and date.
6. Bring the medication list, treatment summary, latest CBC, oncologist contact, and handling precautions to emergency care.

Temperature only if instructed, appetite, water intake, vomiting, diarrhea, energy, weakness, breathing, cough, urinary signs, mouth sores, wounds, and blood-count trends. A dog can be seriously ill without an obvious fever. Write observations in neutral terms with date and time. A home log supports clinical decisions but does not authorize a medication change or replace examination, laboratory testing, imaging, or emergency triage.

Contact the team for any clinic-defined fever, marked lethargy, poor intake, repeated gastrointestinal signs, cough, urinary pain, or wound concern. Fever with profound weakness, collapse, labored breathing, very pale gums, uncontrolled bleeding, or inability to stand requires emergency assessment. When urgent transport is advised, bring the current medication list and call ahead if that does not delay departure.
