Dose regimens2
This calculator performs arithmetic only on the sourced dosing field shown for each result — it does not verify the field's accuracy, does not select which field to use for a patient, and does not replace a veterinarian's order. Not for clinical use. Confirm every result against the primary source before dispensing.

In experimental dogs, telmisartan 1 mg/kg beat enalapril for BP control — but no well-controlled clinical trials in dogs exist in this edition; ACE inhibitors remain first-line.

Losartan is a poor choice in dogs (relies on an active metabolite dogs don't produce); telmisartan needs no metabolic activation.

ARBs are less likely than ACE inhibitors to cause hyperkalemia and are generally better tolerated in humans — the rationale when ACEi side effects force a switch.

Pregnancy / lactation considerations1
Do not use in pregnant animals (ARBs are fetotoxic — renin-angiotensin system role in fetal renal development).
