The Importance of Blood Sugar Regulation in Dogs

Canine diabetes mellitus is a chronic condition where the body either doesn’t produce enough insulin or can’t utilize it effectively. Insulin is responsible for unlocking cells, allowing glucose (sugar) from the bloodstream to enter and fuel the body. When this process is disrupted, blood sugar levels fluctuate, posing health risks.

There are two main types of diabetes in dogs:

Type 1 Diabetes: The pancreas produces little to no insulin, requiring lifelong insulin injections.
Type 2 Diabetes: The body produces insulin but becomes resistant to its effects. Management often involves dietary changes and may incorporate insulin injections in some cases.

Regardless of the type, consistent blood sugar control is essential for a diabetic dog’s well-being. It prevents complications like diabetic ketoacidosis (DKA), a life-threatening condition caused by a severe lack of insulin.

Which Insulin Is Best for Dogs?

Selecting the best insulin products for diabetic dogs is crucial for effective management of the condition. Veterinary-specific insulin formulations such as Vetsulin and Caninsulin are commonly recommended due to their proven efficacy and safety profiles. These products are designed to mimic the dog’s natural insulin cycle, offering a blend of both intermediate and short-acting insulin.

Human insulins like Humulin or Lantus are also used to treat diabetes mellitus in dogs, though they may require careful dosing adjustments. It’s essential to work closely with a veterinarian to determine the most appropriate insulin type and dosage for each individual dog, as factors like the dog’s size, weight, and specific health conditions play a significant role in treatment success.

What Happens If You Give a Dog Too Much Insulin?

Insulin’s primary function is to unlock cells, allowing glucose (sugar) from the bloodstream to enter and fuel the body. When too much insulin is administered, blood sugar levels plummet, leading to a state of hypoglycemia. This disrupts vital bodily functions that rely on glucose for energy.

Here’s a breakdown of the effects of an insulin overdose:

Cellular starvation: Cells deprived of glucose, their primary energy source, begin to malfunction.
Nervous system dysfunction: The brain, heavily reliant on glucose, suffers impaired function, leading to neurological symptoms.
Organ damage: In severe cases, prolonged hypoglycemia can damage vital organs like the liver and kidneys.

The severity of the insulin overdose and the resulting symptoms depend on the amount of excess insulin and how quickly blood sugar levels drop. Early detection and intervention are crucial to prevent serious complications.

Signs of Insulin Overdose in Dogs

Early detection of insulin overdose is critical for preventing serious complications. Here are the signs to watch out for, categorized by severity:

Mild Signs:

Disorientation and confusion
Weakness or lethargy
Shivering or trembling
Hunger pangs or restlessness
Excessive drooling

Moderate Signs:

Difficulty walking (ataxia)
Seizures or tremors
Pale gums
Loss of consciousness for brief periods

Severe Signs:

Diabetic coma (prolonged unconsciousness)
Difficulty breathing
Convulsions

The severity of symptoms depends on the degree of blood sugar drop. Be mindful that some dogs, particularly those experiencing frequent hypoglycemia, may exhibit subtle signs or none at all.

Important Note: If you suspect your dog has overdosed on insulin, do not wait for all the signs to appear. Immediate action is critical.

Diabetic Coma in Dogs

A diabetic coma, a harrowing complication in diabetic dogs, arises when blood sugar levels plummet and remain dangerously low for a prolonged period. This severe lack of glucose, the brain’s primary energy source, disrupts vital functions, jeopardizing your dog’s well-being.

Causes of Diabetic Coma

Untreated hypoglycemia: When insulin overdose or other factors cause a significant drop in blood sugar that goes unnoticed or remains untreated, it can snowball into a coma.
Missed insulin doses: Skipping or delaying insulin injections can lead to a rapid decline in blood sugar levels, potentially triggering a coma.
Concurrent illnesses: Infections, digestive issues, or other illnesses can affect insulin absorption and exacerbate blood sugar fluctuations, increasing the risk of coma.

Signs of Diabetic Coma

Early recognition of these signs is critical for prompt veterinary intervention and improving your dog’s chances of a full recovery.

Loss of consciousness: This is the most obvious sign, with your dog appearing unresponsive and unable to be awakened.
Weak or absent pulse: A weak or barely detectable pulse indicates a significant decline in bodily functions.
Shallow or labored breathing: Difficulty breathing, with rapid, shallow breaths or labored gasps, signifies a struggle to maintain vital processes.
Muscle stiffness: The body may become rigid or exhibit involuntary muscle contractions.
Dilated pupils: Enlarged pupils that are unresponsive to light point towards a compromised nervous system.

What to Do If You Suspect Your Dog is in Diabetic Coma

If you think that your dog has entered a diabetic coma, time is of the essence. Here’s what to do:

Seek immediate veterinary emergency care: Don’t attempt to treat the coma yourself; rush your dog to the nearest veterinary emergency center.
Gather information: While en route, gather any relevant details about your dog’s condition, including insulin dosage, time of last injection, recent illnesses, and any observed symptoms. This information helps the veterinarian assess the situation quickly.

Remember, a diabetic coma is a medical emergency. By recognizing the signs, acting swiftly, and seeking immediate veterinary care, you can give your dog the best chance of recovery.

Taking Action in Case of Insulin Overdose

If you suspect your dog has overdosed on insulin, time is of the essence. Here’s what you should do:

Remain calm: While the situation is urgent, panicking can hinder clear thinking.
Check blood sugar (if possible): If you have a home blood glucose monitor, use it to check your dog’s blood sugar level. This information can be valuable for the veterinarian.
Administer a source of glucose (if blood sugar is low): If your dog is conscious and alert, you can administer a small amount of a readily absorbed sugar source like karo syrup or honey (applied directly to the gums), or a commercially available glucose gel.
Contact your veterinarian immediately: Regardless of the severity of symptoms, prompt veterinary attention is crucial. Explain the situation in detail, including the amount of insulin administered, the time of injection, and any observed symptoms.
Do not induce vomiting or give any medications: Unless specifically instructed by your veterinarian, avoid inducing vomiting or administering any medications. This can further complicate the situation.

How to Prevent Insulin Overdose in Dogs

While knowing how to react to an insulin overdose is crucial, prevention is always the best medicine. Here are some proactive measures you can take to minimize the risk of an overdose in your diabetic dog:

Prioritize accurate diagnosis and dosing: A proper diagnosis by your veterinarian is vital. They will determine the type of diabetes, assess your dog’s individual needs, and prescribe the appropriate insulin type and dosage. Regular blood sugar monitoring helps fine-tune the dosage over time.
Practise consistent Injection technique: Using the correct injection technique ensures accurate delivery of the insulin dose. Ask your veterinarian to demonstrate the proper technique and practice at home before starting injections.
Focus on meticulous record keeping: Maintain a logbook to record the date, time, and amount of each insulin injection. This detailed record helps identify patterns and potential inconsistencies.
Keep a consistent feeding schedule: Maintaining a consistent feeding schedule helps regulate blood sugar levels and prevents fluctuations that might necessitate dose adjustments. Discuss the ideal feeding plan with your veterinarian.
Recognize signs of illness: Conditions like infections or digestive issues can affect insulin absorption and blood sugar levels. Be mindful of any changes in your dog’s behavior or appetite, and promptly inform your veterinarian if you notice anything unusual.
Prioritize regular veterinary checkups: Schedule regular checkups with your veterinarian for blood sugar monitoring, overall health assessments, and potential dose adjustments as needed.
