Indication: Canine parvovirus enteritis (PCR / SNAP positive, or strongly suspicious history — unvaccinated puppy with severe vomiting / haemorrhagic diarrhoea / leukopenia).

What this protocol does:
• High-rate IV crystalloid (LRS) to correct dehydration and ongoing GI losses
• Anti-emetic cover (maropitant q24h IV) for nausea + protection from oesophagitis
• Broad-spectrum IV antibiotic (ampicillin q8h) to cover for bacterial translocation across damaged gut mucosa
• Round-the-clock temperature monitoring (q4h) — the only one of the system protocols with full 24-hour vitals coverage

Monitoring: temperature q4h, PCV/TS daily, glucose if collapsed.
Escalate to ICU / extended care if: persistent vomiting after 24h of treatment, sustained hypoglycaemia, sepsis signs (hypothermia, hypotension), or sudden collapse.
