The Canitide Pen

Dial the dose. Not the math.

A reusable pen that takes sealed, pre-mixed 3 mL cartridges. Twist on a needle, dial your dog’s units, press. Ten seconds. The same motion, every formula.

The Canitide Pen

Dial the dose, not the math

Vial protocols make owners convert milligrams to milliliters to insulin-syringe ticks. The pen dials units. Your band is on the card that comes in the box.

Pre-mixed, so nothing gets wasted

Reconstitution errors are the most common mistake in home dosing. Canitide cartridges arrive mixed in bacteriostatic water at a fixed concentration, sterility-tested lot by lot.

A needle your dog barely notices

32-gauge, 4 mm. Shorter and finer than the insulin syringes most vial kits ship with. Most dogs keep eating their breakfast.

One pen, every formula

Swap a REPAIR cartridge for COAT in ten seconds. The pen is yours for years; only the cartridges refill.

Six steps

How to dose.

  1. LoadUnscrew the body, drop in a cartridge, screw closed.
  2. AttachTwist a fresh 32G pen needle onto the tip. Remove both caps.
  3. PrimeDial 2 units, point up, press until a drop appears. Once per new cartridge.
  4. DialTurn the dial to your dog’s units. Big numerals, a click per unit.
  5. DoseLift loose skin at the scruff or flank, press the button, hold five seconds.
  6. DoneCap the needle, drop it in the sharps container, cartridge back in the fridge.
