An implant injector for animals is adjustable for implant insertion depth. The distance, that the injector needle or cannula, extends past the nose of the injector is adjustable. The insertion depth adjustment is accomplished by moving the nose of the injector relative to the tip of the cannula that extends past the nose. In addition to adjusting the insertion depth, the cannula or needle, may also be rotated to a plurality of positions relative to the injector handle. A spring loaded plunger, when released by a release button, will push the implant out the end of the cannula as the operator withdraws the cannula from the animal. The release button is designed as a safety trigger to avoid premature activation of the plunger during insertion of the needle. Needles, or cannulas of various diameters and lengths, may be interchanged in the injector. Also, the spring loaded plunger for expelling the implant may be removed allowing the operator to replace the plunger with a different diameter and length plunger, if desired, to match different size cannulas.
