An animal syringe system for injecting animals with a syringe using a delivery system that allows application at a distance away from the animal. The animal syringe system includes a drug-dispensing syringe inserted into an inner syringe sleeve correspondingly inserted into a two-sized compression spring inserted into an outer sleeve. This assembled drug-dispensing projectile is loaded into a velocity adjustable air rifle. The drug-dispensing projectile is fired at an animal with the syringe needle impaling the animal. A trip device is then triggered releasing tension springs on the plunger of the syringe which injects the drug dose into the animal. As the plunger reaches its endpoint it triggers a two-sized spring inside the outer sleeve which pushes the inner sleeve and syringe away from the animal and the front end of the outer sleeve. As the syringe needle retracts completely into the outer sleeve the drug-dispensing projectile falls harmlessly to the ground.
