That's too bad.. baytril is more painful than some of the other antibiotics. It's pretty strong and can burn and even cause scar tissue. I don't blame the big guy for not liking it.

Your vet showed you to do the injection in the first third of the body (probably about 2' down from the head on your snake) on either side of the spine in the muscle? Not straight up and down.. at an angle and between the scales (this makes it easier)

Just making sure you were taught correctly.. I haven't had a snake react that negatively to a shot before.
