I have a shihtzu with diabetes. He gets insulin shot twice

This answer was rated:

I have a shihtzu with diabetes. He gets insulin shot twice daily and then food. Last night he was sick and threw up food. This morning he threw up even his water. I did not give him his insulin shot since he was throwing up. Tonight he will not eat even a treat but he is very thirsty. Should I give him insulin shot anyway although he is not eating. I thought he had to eat after getting the insulin shot.
Hello - I am Dr. Matt - I would be glad to help you with your question.

When is the last time that he ate anything?

Is he having any diarrhea?

Is he urinating more then normal?

Does he seem lethargic?

He ate last night but got sick. He does not have diarrhea. He is urinating a lot as he is drinking a lot of water. Actually he always urinates a lot anyway. Sleeping a lot.
Thank you for the additional information.

I am very sorry to hear that he is not eating and is not feeling well. I would not give him an insulin injection tonight since he is not eating. At this point, since we do not know exactly where his blood glucose level is, giving him insulin could potentially be quite dangerous. Based on his symptoms, his blood sugar may be much higher then normal as a disorder called Diabetes Ketoacidosis is possible (this is where the blood sugar remains above 500 for a prolonged period of time). This disorder causes dogs to not want to eat, vomit, act very lethargic and they can become quite dehydrated. This can be a very serious disorder that usually does require immediate veterinary attention to get him started on IV fluids and a shorter acting insulin called regular insulin to get his blood sugar back to the normal range.

Even though his blood sugar may be higher then normal, giving him insulin when he is not eating and not knowing where his blood sugar is can be dangerous therefore I would not give him any insulin until his blood sugar is checked. If he seems to be comfortable and is not vomiting very much tonight you could wait until tomorrow morning to have your vet examine him and check his blood sugar though if he does seem to be having any labored breathing, more vomiting, he acts very lethargic, and uncomfortable I would take him to a vet tonight to get immediate help.

Thank you. That was my concern as to whether or not to give him his insulin shot now. He is not vomiting tonight and he seems comfortable. I will see his vet in the morning.
You are very welcome! I hope he feels much better very soon.
