Glucose and insulin are two important keywords to understand regarding diabetes.

When your dog consumes food, the nutrients in the food are converted to energy to keep the bodily functions going. Glucose is one of the byproducts of the nutrient breakdown process. It is a type of sugar that is fuel for various cells and organs. The blood absorbs the glucose and transports it through the body.

Your dog’s pancreas produces a hormone called insulin. The hormone is responsible for regulating the level of glucose in the blood. It informs the cells to pick the glucose absorbed in the blood.

Diabetes mellitus is a disease that occurs when the glucose and insulin connection breaks. There are two types of diabetes:

  • Type 1: This is the most prevalent type of diabetes in pets. If your dog’s pancreas is not working as expected, they do not produce enough insulin for the body. This type is also referred to as insulin-deficiency diabetes.
  • Type 2: In this type, the pancreas produces insulin, but the other hormones in your dog’s body prevent insulin from being used as intended. They are also known as insulin-resistance diabetes.

Regardless of the type, diabetes leads to high sugar levels in the blood, while the cells and organs that need this sugar for energy cannot access them.

The usual treatment plans for canine diabetes are:

1. Insulin Injections

In the case of insulin-deficiency diabetes, your dog will need insulin shots twice a day. The vet will prescribe the initial dose and type of insulin. Then, the dosage will be adjusted according to the body’s reaction to the treatment.

Your dog cannot consume insulin orally; it has to be taken in the form of injections. The needle is small, and the process is not so painful. Your pet can tolerate injections very well.

The vet will demonstrate the process of giving the shot under the skin. Pay close attention and ask questions, if any, because you will have to administer these injections daily.

2. Diet

The vet will recommend a diet depending on your dog’s age, weight, and activity level. Ensure you stick to the given calorie range.

Fiber helps to slow down the process. It makes your dog feel fuller for a longer time. Thus, vets usually recommend a high-fiber, low-fat diet. The fewer calories in low-fat food help with weight loss.
