Indications of Glucose Levels in a Senior Dog

Just like humans, dogs can develop diabetes--known as diabetes mellitus--as they age and it's important to pick up on the warning signs of glucose levels as they rise. The veterinarian needs this information so he can help with the treatment. When glucose levels rise, watch for a number of risk factors and symptoms.

  1. Increased risk factors

    • Obesity could increase a dog's risk. Genetics play a role as well, as some breeds are more predisposed to diabetes mellitus. Those breeds include golden retrievers, poodles, keeshonds, pulis, cairn terriers, miniature pinschers, miniature schnauzers, dachshunds and beagles.

      Any disease that interferes with insulin production increases the risk of higher glucose levels. Some conditions that affect hormones, such as when the dog is in heat or pregnant, can raise levels. Diseases such as cushing's syndrome and acromegaly can interfere with insulin.

      Pancreatitis and viral infections also can cause diabetes mellitus. These diseases destroy pancreatic cells.

    Signs to look for

    • If your dog has increased glucose levels, you will see signs in his behavior or actions.

      If the dog has increased thirst or appetite, that might be a sign. It may have to urinate more often.

      If the dog suddenly has unexplained weight loss, inform your vet.

      If it develops cataracts, that may be a sign that glucose levels are high and affecting your dog's vision.

    Advanced stages

    • If the glucose levels have been high for a while, your dog's symptoms will change. It will have decreased appetite. Vomiting, lethargy and dehydration also are symptoms.

      If these start to occur, take your dog to the veterinarian quickly. The doctor will perform blood tests to confirm that its glucose levels are high.
