My dog got too much insulin. Is kidney damage a risk from low glucose?

Updated On September 23rd, 2025

Pet's info: Dog | Miniature Pinscher | Male | neutered | 14 years old | 11 lbs

I made the mistake of giving dog 5 units of nsulin today when his glucose was only 182. Vet was fortunately in office because within 2 hours dipped down to 50s. We got it up finally this afternoon. 145 pm 71 325 pm 157 / 435 pm 154/ 7 pm 67 - so I gave him no insulin at 7 feeding time. Gave him the 1/2 can (15 oz.) W/D along with 1/4 c. W/D dry food and 1/8c pedialyte (he had not been drinking all day). 9 pm glucose 170, then at 11 pm 294. I am worried about his kidneys since Friday blood work

The best way to proceed now is to give Spike his regular amount of insulin when it is due the next time. From what you are reporting this episode should not have affected his kidneys negatively, as usually it is the very high blood sugar levels that cause kidney damage. I suggest giving him the regular insulin dose tomorrow with his food given, and then check blood glucose level approx. 6 hours after the dose of insulin was given.
