My dog was recently diagnosed with diabetes, so I have been giving her twice-daily insulin injections for the past 10 days. I've watched my vet do it, I've watched dozens of YouTube videos, and I've read everything I can find about the proper technique, but somehow, I can't seem to get it right.
Every time I inject my dog, she fidgets when I insert the needle, but not overly much, but as soon as I begin to inject the insulin itself, she yelps and either jerks away, or tries to bite me. More than once I've ended up with bent syringes and insulin on her fur because of it.
I'm following the procedure as shown, for example, in this video: https://www.youtube.com/watch?v=6jOEKUTU-Ac
Take the insulin out of the fridge and roll it around to mix it up.
Draw out slightly more than the needed dose into a new fresh syringe, tap out the air bubbles, then return the excess.
Allow the syringe to warm up in my hand for several minutes as I prepare and put out the dogs' food.
After my dog is finished her meal, I pull her onto my lap and find a place where the skin is loose. I have been rotating between left and right shoulder and left and right rump so far.
Pull up a fold of skin ("tent" it) between my fingers.
Push the needle into the middle of the folder at ~45 degree angle
Slowly inject the contents of the syringe.
From everything I've read, this is supposed to be so painless that the dog may not even acknowledge that anything happened, but my dog is getting progressively more anxious each time I do it. I thought I would have gotten the hang of it by now, but I seem to be getting worse.
My main concern is that I'm doing something wrong and injecting the insulin incorrectly; my vet said something about making sure I was doing a subdural and not an intradermal injection, but how would I know? As far as I can tell I'm getting the needle beneath the skin correctly: it's hard to tell with my dog's long hair, but I'm not feeling any resistance to either the needle or the fluid, and the needle's not coming back out of the skin.
(I've done the practicing on the orange bit, and I think I have it right, but oranges don't yelp when you mess up :( )
Is there something else I can do to make sure I do this injection properly, or at least reassure myself that I'm not hurting my dog and that her insulin is going where it should?
