Stopping insulin injections in a diabetic dog causes blood sugar to rise to dangerous levels (hyperglycemia), starving cells of energy and leading to a life-threatening, emergency condition called diabetic ketoacidosis (DKA). Symptoms include severe weakness, vomiting, lethargy, acetone-smelling breath, and, without immediate veterinary intervention, death.

How many days can a diabetic go without insulin?

A person with Type 1 diabetes needs insulin to live; without it, they can become severely ill and die from Diabetic Ketoacidosis (DKA) within days to a week or two, with symptoms starting in hours, especially if they are sick or making no insulin at all. For Type 2 diabetes, someone making some insulin might last longer, but eventually, they also need insulin to avoid severe hyperglycemia (HHS) and long-term complications like blindness or amputation, with severe risks developing over days, weeks, or months without it. Missing even basal (long-acting) insulin for even a day is considered unsafe for insulin-dependent individuals, as the body needs that baseline supply to function, leading to DKA or HHS.
