Equine Dosage Guidelines
Standards for large animal care. Weight estimation, NSAID safety (Bute/Banamine), and colic management.
⚖️ Weight Estimation
Accurate weight is the biggest challenge in equine dosing. "Eyeballing" often leads to underdosing (ineffective) or overdosing (toxicity).
Weight Tape Method
Place the tape around the heart girth (just behind the elbow and withers). Pull snug
but not tight.
Accuracy: +/- 50-100 lbs
The Formula
(Heart Girth² × Length) ÷ 330 = Weight (lbs)
More accurate than taping alone.
💊 Essential Medications
Phenylbutazone ("Bute")
Primary Use: Musculoskeletal pain (lameness, arthritis).
Flunixin Meglumine ("Banamine")
Primary Use: Visceral pain (Colic) and ocular inflammation.
Sedatives (Dormosedan, Xylazine)
Used for farrier work, dentistry, or clipping. Extremely potent. Handled carefully to avoid human absorption through skin/mucosa.
🚨 Colic Protocol
If you suspect colic (pawing, rolling, looking at flank), check vitals BEFORE administering medication if possible.
"Banamine can mask surgical colic symptoms. Consult vet immediately."
