from Endocrine Vet
"Insulin can also be diluted with sterile water or saline solution, but these insulin solutions are not as stable."
- translation, don't mix up a huge batch and expect it to be consistent. Only mix what you might need for 1 dose, or 1 day. And be careful!
If you have a sterile mixing vial, sterile saline vial, and your insulin vial, theoretically, you could measure equal amounts of insuline and sterile salin, put them in the mixing vial, roll thoroughly, then pull out what you needed for 1 day.
I recall reading on a Children with Diabetes page how a parent might draw up X amount of insulin, plus X amount of diluent, roll it around in the syringe, then discharge any excess before shooting.
Also
"ProZinc™ insulin is a sterile aqueous protamine zinc suspension of recombinant human insulin.
Each mL contains:
recombinant human insulin...........................40 International Units (IU)
protamine sulfate....................................0.466 mg
zinc oxide...........................................0.088 mg
glycerin............................................16.00 mg
dibasic sodium phosphate, heptahydrate.............. 3.78 mg
phenol (added as preservative)...................... 2.50 mg
hydrochloric acid................................... 1.63 mg
water for injection (maximum)....................... 1005 mg
pH is adjusted with hydrochloric acid and/or sodium hydroxide."
Note that ProZinc is mostly water.
Ah luvs der interwebs!

I don't see that you need to give any less than you are giving although you could try .1 on the U 100 syringes. Is the idea that you could shoot lower numbers with diluted insulin? I'd much rather see you stick with your scale and if you really want to shoot at numbers under 100, then shoot a drop or .1. Don't waste your precious financial resources on more equipment to do a unproven, untried method.

Lowering the insulin dose— You certainly could dilute the NPH insulin and lower the insulin dose to 0.5 U twice a day. Both Eli Lilly and Novo Nordisk make diluents for their brand of NPH insulin, but these diluents can be difficult to obtain (5). Insulin can also be diluted with sterile water or saline solution, but these insulin solutions are not as stable.
My Bottom Line
You certainly could lower the NPH insulin dose, but I don't think that's the best solution for this dog. I would recommend switching to a longer-acting insulin preparation, such as ProZinc or Lantus. Although not generally considered as first-choice insulin preparations, both of these long-acting insulin preparations have been reported to be effective in dogs (9,10). Because they are slowly absorbed, both of these insulins have a less potent hypoglycemic effect as compared with NPH insulin.
However, we can't forget about the "premixing" of the insulin dose that the owner does on the weekends, can we! When we throw that into the equation, my choice becomes more obvious. Let's change to Lantus, which is a solution so the insulin won't precipitate out of suspension like the premixed NPH insulin would likely do.
Just because no one has posted it here, does not mean it hasn't been done anywhere. Its unfamiliar, certainly.
