Maintenance & Deficit
Simple: Dogs 60 ml/kg/day, Cats 50 ml/kg/day. RER-based is more conservative for renal/critical patients.
5%
⚠ 8–10% dehydration suggests moderate to severe deficit. Immediate IV correction is usually required.
🚨 Above 10% dehydration may need a resuscitation bolus before maintenance planning.
Mild <5% · Moderate 6–8% · Severe 8–10% · Critical >10%
Phase 1 = deficit corrected over this window. Phase 2 = maintenance + losses for remaining hours.
Ongoing Losses
ml/kg/hr — vomiting / diarrhoea (e.g. 1–4 ml/kg/hr)

Clinical Notes:
• Starting estimates only; reassess every 4–6 hours.
• Deficit should usually be corrected faster in shock/parvo and slower in renal/cardiac patients.
• If dehydration is severe, give a resuscitation bolus before following the maintenance plan.
• Volumetric pumps are preferred over manual drip estimation in critical patients.
