Oh gosh...

I just realized I bought U-100 syringes trying to give 3 units of insulin but only pulling it to 3 on the syringe which means Im giving him a lot less insulin than 3 units right?

So I should be pulling the syringe to 7.5 if he's on caninsulin with u 100 syringe? What if I already gave him up to the 3 mark on the syringe this morning? I was doing an insulin curve last night wondering why nothing was changing. Should I give him more? It's been 2 hours since I gave it. Oh boy :(
 
Here's the conversion chart for using U40 insulins with U100 syringes (very helpful!):

Sorry you didn't get a reply till now. I hope you didn't give any more insulin (please post to confirm that you didn't give more insulin - it's really important for people responding to your thread to know that). No matter what happens with the dose measurement or with a hiccup when you're giving the injection (e.g. a fur shot) the rule is not to give another dose of insulin until the next dose is due. (It would be very, very dangerous to attempt to do otherwise.)

Correct, you put up a U40 insulin to the 7 1/2 unit mark on a U100 syringe to get 3 units of the a U40 insulin.
With Caninsulin/Vetsulin you can give the remiander of the 3 real units at two hours since Vetsulin/Caninsulin only lasts 8-10 hours. I myself would just pull up the U40 insulin to the 4 unit marking on a U100 syringe and inject that
 
If you have half unit markings on a U-100 syringe, every tick mark equals 0.2 units of a U-40 insulin.
That is because there are only 40 units per mL, or 40% of the concentration of a U-100 insulin.
