    Inject the needle. Either side of the neck is most common. For small lambs normally you pinch the skin and inject the liquid parallel to the skin and for full grown sheep you can jab it into the meat. When the needle goes in you should hear a pop noise.

    Make sure you store the vaccinations properly when you have finished injecting the sheep. Putting them in the bottom of your fridge is a suitable place.


  • If you jab the needle directly into the meat of a lamb, it can damage the muscle tissue.
  • If you inject yourself call the Poison Hotline immediately.
  • Do not inject the needle in a dirty area; otherwise it might become infected.
  • It is a good rule to replace the needle once for every 20 sheep.
