Canine diabetes is a condition where a dog's body cannot properly produce or use insulin, a hormone that regulates blood sugar levels. This leads to high blood sugar, which can cause various health issues. There are two main types: Type 1 diabetes, where the pancreas produces little to no insulin, and Type 2 diabetes, where the body becomes resistant to insulin. Symptoms of canine diabetes include increased thirst, frequent urination, weight loss, and lethargy. If left untreated, it can lead to serious complications, such as ketoacidosis or damage to organs. Early diagnosis and management, including a special diet and insulin therapy, are crucial for maintaining a dog's health.
