Vasopressin is used in dog for CPR, refractory hypotension. Routes documented in dog: IV. A typical adult dog weighs 2.00–80.00 kg. ExoticRx lists 1 cited dose rule for Vasopressin in dog, drawn from published veterinary references. Verify against current literature before clinical use.
Trade names: Pitressin, Vasostrict
| Route | Dose | Frequency | Duration | Indication | Evidence | Source |
|---|---|---|---|---|---|---|
| IV | 0 mg/kg | 0.2-0.8 U/kg IV bolus or CRI 0.5-5 mU/kg/min | During CPR or critical hypotension | CPR, refractory hypotension | Moderate | Plumb's Veterinary Drug Handbook, 9th Ed |
One of the cited rules is a continuous-rate-infusion regimen: IV 0 mg/kg 0.2-0.8 U/kg IV bolus or CRI 0.5-5 mU/kg/min. CRI regimens are delivered as a continuous infusion rather than discrete doses — verify the rate against the cited source before use.

Acts on V1 (vascular smooth muscle vasoconstriction) and V2 (renal collecting duct water reabsorption) receptors. Non-catecholamine vasopressor.
Used in CPR and refractory hypotension. Digital/splanchnic ischemia risk. Does not require functioning adrenergic receptors. Monitor urine output.
Species-specific contraindications and adverse-reaction reports for dog may differ from canine / feline reference data — consult the primary citations listed with each rule.
Why a species-specific page? Vasopressin pharmacokinetics differ across species: dose ranges, intervals, and route preferences are not interchangeable. Cross-extrapolation from canine doses is unsafe in dog — the rules above are the citations specific to this species, not generic recommendations.
