134 isn't too low to shoot once you've got some experience. There's no guarantee that he wouldn't need monitoring more than 4 hours though.
Your choices are to shoot the full dose - which an experienced person would shoot everything over 50ish.
You can shoot a reduced dose, like 0.25u which you did last time you had a number in the 130's.
You can wait and test again, without feeding, and then shoot the full dose when his BGs begin to rise - the down side of that is that it will put you off schedule for his next shot. YOu need a 12 hr interval between shots.
You can skip the shot entirely.
I'd choose one of the first two options, although it's of course, up to you. Have you read through the "Shooting & Handling Low Numbers" sticky? It's written for those following Tight Reg, but it has some good information that would apply to anyone using Lantus.
If you shoot tonight, I'd get a +1 and a +2 and decide based upon those tests when to test next. I can check in with you tonight to see if you need help, if you do decide to shoot.
What would you like to do?
