Know About Canine Diabetes?

Canine diabetes is a medical condition in dogs that is very similar to human diabetes. It occurs when a dog’s body is unable to use or produce sufficient quantities of a hormone called insulin.

Function Of Insulin?

It helps move sugar (glucose) from the food your dog eats into their cells to give them energy. Imagine your dog eats a bowl of food. That food turns into sugar in their body. Insulin is supposed to “unlock” the cells so the sugar can go in and be used for energy.

What occurs with diabetes?

With diabetic dogs, there is not enough insulin or the body doesn’t use it properly. The sugar stays in the blood rather than going into the cells. This results in high blood sugar (hyperglycemia). If a dog has high blood sugar and it is not treated, it will make your dog sick.

Blood Glucose Levels in Dogs (Normal & Diabetic Ranges)

Life Stage	Normal Glucose Level (mg/dL)	Mild Fluctuation (Monitor Closely)	Diabetic Range (mg/dL)

Puppy (0–6 month)

75 – 120 mg/dL

60 – 140 mg/dL

> 180 mg/dL (fasting)

Growing (6–12 month)

75 – 120 mg/dL

60 – 150 mg/dL

> 180 mg/dL (fasting)

Adult (>1 year)

75 – 120 mg/dL

60 – 150 mg/dL

> 180 mg/dL (fasting)

Types of Diabetes Seen in Dogs vs Humans-

Type	In Dogs	In Humans	In Simple Words	Example
Type 1 (Insulin-Dependent Diabetes)	✅ Most common in dogs	✅ Common in kids and young adults	The body can’t make insulin at all	Like a factory that shut down insulin production completely—needs insulin shots every day
Type 2 (Insulin-Resistance Diabetes)	❌ Rare in dogs	✅ Common in adults (often due to weight/lifestyle)	The body makes insulin, but it doesn’t work properly	Like having the key to open a door, but the keyhole is jammed
Gestational Diabetes	❌ Very rare in dogs	✅ Happens during pregnancy	Temporary diabetes that occurs only during pregnancy	Like a sugar traffic jam during pregnancy—usually goes away after birth

---

🐶 Note-

• Most dogs have Type 1 diabetes → they need insulin shots for life
• Type 2 and Gestational diabetes are rare in dogs, but common in humans
• Like people, diabetic dogs need a careful diet, regular exercise, and medication

Causes / Main Risk Factors for Diabetes in Dogs-

1. Genetical/Heredity factor (Family History)
   • Some dogs are born with a higher chance of getting diabetes because of their genes.
   • 🐶 Example: Breeds like Poodles, Dachshunds, and Beagles are more likely to get diabetes.
2. Overweight ( Obesity)
   • Too much fat in the body can block insulin from working properly.
   • 🐕 Like in humans, overweight dogs are at higher risk for diabetes.
3. Problem in Pancreas
   • Insulin is made by pancreas, If there is any damaged or inflamed (called pancreatitis), it may stop making enough insulin.
   • Sugar builds up in the blood in absence of insulin.
4. Hormonal Imbalances
   • Some female dogs can develop diabetes due to hormone changes, especially if not spayed.
   • One hormone called progesterone can block insulin.
5. Certain Medications
   • Long-term use of steroids (like prednisone) can cause blood sugar levels to go too high.
   • These are often used to treat allergies or inflammation.
6. Age
   • Diabetes is more common in middle-aged and older dogs (usually 5 years and up).
   • Just like people, the risk goes up with age.
7. Infections or Diseases
   • Some infections or illnesses can damage organs that help control blood sugar.

Symptoms of Diabetes in Dogs On Different Body Organs/System-

Organ / System	Main Symptom	What it Means	What You Might Observe
Urinary System	Excessive urination (polyuria)	High sugar in the blood pulls water into the urine	Your dog pees more often, even indoors or at night
Digestive System	Increased hunger (polyphagia)	Cells aren’t getting sugar, so the body thinks it’s starving	Your dog eats a lot but still loses weight
Weight	Weight loss	Body starts burning fat and muscle for energy	Your dog eats normally (or more) but gets thinner
Thirst	Excessive drinking (polydipsia)	Losing a lot of water through urine makes the dog very thirsty	Your dog drinks water constantly, bowls empty fast
Eyes	Cloudy eyes / cataracts	High blood sugar can damage the lens of the eye	Your dog’s eyes look cloudy or milky; they may bump into things
Skin & Coat	Dull coat or hair loss	Poor nutrition from diabetes affects skin and fur	Coat looks dry, rough, or patchy
Energy Levels	Low energy / fatigue	Cells aren’t getting enough energy from sugar	Your dog is tired, less playful, or seems depressed
Immune System	Slow healing, frequent infections	High sugar weakens the immune system	Cuts take longer to heal, or your dog gets more skin or bladder infections
Muscles	Weakness in back legs	Nerve damage from long-term high blood sugar	Your dog may walk wobbly or have trouble standing up

If you observe two or more of these symptoms in your dog, it’s better to visit the nearest veterinary aid for a diabetes check-up. Early treatment can save your dog’s health and life.

How Diabetes In Dogs Affects Their Behavior-

1. Loss Of Energy Or Tiredness–
   • The overall behavioral change for dogs with diabetes is lethargy, or, decreased playfulness. This is because the cells are not receiving enough sugar (energy) for their body to feel “normal.” When dogs with diabetes are feeling worn out or are tired the first thing to understand is that the dog is tired from exertion – even if it has not done anything, it is still tired from previously exerting itself – they usually all do that in some fashion.
2. Excessive Eating–
   • Your dog may be constantly begging, or acting obsessive towards food, even if it has been fed. This is because the body thinks it’s starving, due to the cell’s inability to uptake sugar, causing it to yell for energy.
3. Frequent Urination (Accidents)
   • Typically house-trained dogs may suddenly have surprising urine accidents. Increased sugar in the blood causes increase amounts of urine to be excreted and it is possible your dog couldn’t hold it as it normally does.
4. Excessive Drinking Of Water-
   • If your dog is pacing back and forth to the water bowl and is acting anxious or restless because it is empty, that dogs body is attempting to rehydrate from excessive urination.
5. Changes in Vision or Bumping Into Things-
   • Cataracts from diabetes can occur, which will impair vision. Dogs may show confusion, bump into furniture, and/or hesitate in different places because they could be afraid or don’t know if its safe.
6. Changes in Attitude/mood-
   • They may just be mad, sad and/or act more attached to you, for no apparent reason. Pain, discomfort and/or its not feeling normal can change how your dog behaves with you or other pets.
7. Pacing or Restlessness
   • Some dogs may pace or appear restless, particularly when blood sugar is high or low.
   • This may appear as nervous behavior or even anxiety.
8. Sudden Confusion or Disorientation
   • Very high and very low blood glucose can affect the brain.
   • Your dog may appear dazed, act lost in familiar environments or not respond to their name.

Diagnosis Tests Of Diabetes in Dogs vs Humans-

Diabetes In Dogs Can Be Checked By Below Listed Tests-

Test	Description	Instrument Used	Dogs	Humans	Economic Aspect	Reliability
Blood Glucose Test	Measures blood sugar level	Glucometer	Commonly done via blood from paw/ear; devices specialized for dogs	Usually finger prick; glucometers widely available	Moderate cost; dog-specific meters more expensive	Highly reliable if done properly in both
Fructosamine Test	Shows average blood sugar over 2-3 weeks	Laboratory blood test analyzer	Frequently used to monitor diabetic dogs	Used to monitor diabetes control in humans	Lab test cost moderate to high	Reliable indicator of long-term sugar control
Urine Glucose Test	Detects glucose in urine	Urine test strips (Ketostix, Diastix)	Easy but less accurate; screening tool only	Used but less favored; blood tests preferred	Low cost; cheap and easy	Less reliable; false positives/negatives possible
Oral Glucose Tolerance Test (OGTT)	Measures blood sugar response to glucose drink	Blood sampling & lab analysis	Rarely used in dogs due to difficulty	Common for diagnosing diabetes in humans	Higher cost; requires lab work	Very reliable in humans; impractical in dogs
Continuous Glucose Monitoring (CGM)	Measures glucose continuously via sensor attached to skin	CGM device (FreeStyle Libre, Dexcom)	Growing use in dogs; sensors applied to skin	Increasingly common in humans	Expensive initially; sensors last days to weeks	Very reliable and detailed data for both

---

Know About Tests-

OGTT: Tests how well the body clears sugar after drinking a sweet drink (mainly humans).

Blood Glucose Test: Like taking a snapshot of sugar in the blood right now.

Fructosamine Test: Like looking at a sugar “report card” over weeks.

Urinalysis: Checking if urine is leaking sugar – which is not normal.

Glucose Curve: Measures sugar in blood multiple times to assess how insulin works.

Summary:

• Dogs: Diagnosis is mainly blood glucose measurements (AlphaTRAK) and fructosamine lab measurements. Urinalysis is cheap but not good. Continuous glucose monitors (CGMs) in development and potential.
• Humans: Blood glucose and fructosamine measurements are usual measurements for trials, OGTTs (Oral Glucose Tolerance Tests) are usually involve for trial diagnosis. CGMs continuous glucose monitors that we can buy and wear are very common.
• Cost: Cost for routine tests done for dogs is typically higher due to the device being specific to an individual and the vet costs as well.
• Reliability: Blood glucose and fructosamine tests are reliable in both. Urine tests are less accurate. OGTT is mainly human-focused.

Tips for Glucose Monitoring in Dogs:

• Glucometers are the most common home-use devices. Your vet will show you how to collect a small blood drop safely.
• Continuous Glucose Monitors are growing in popularity for better management and less hassle.
• Always keep a log of your dog’s glucose readings to share with your vet.
• Never guess insulin doses—always consult your vet based on monitoring data.

Diseases That Can Be Mistaken for Diabetes in Dogs-

Some diseases that give diabetes like symptoms, should be tested carefully.

Disease	Why It Looks Like Diabetes	How It’s Different	Major Symptoms
Cushing’s Disease	Causes increased thirst, urination, and appetite	Caused by excess cortisol hormone, not blood sugar issues	Pot belly, hair loss, muscle weakness
Kidney Disease	Makes dogs drink and pee a lot	Kidneys can’t concentrate urine, but no high blood sugar	Bad breath, vomiting, weight loss
Urinary Tract Infection (UTI)	Frequent urination and accidents	Infection causes pain and urgency, no high blood sugar	Straining to pee, blood in urine
Hypothyroidism	Can cause weight gain and low energy, sometimes increased thirst	Low thyroid hormone levels slow metabolism, no high blood sugar	Hair thinning, cold intolerance
Pancreatitis	Can cause vomiting, loss of appetite, and abdominal pain	Inflammation of pancreas, may lead to diabetes later	Vomiting, abdominal pain, lethargy
Liver Disease	Can cause increased thirst and urination	Liver problems affect metabolism, not blood sugar	Yellow gums, vomiting, lethargy

Complete Management Practices for Diabetic Dogs-

Diabetes in dogs can be managed with good management practices.

1. Insulin Administration

• Administer insulin according to your vet, generally twice a day.
• Learn proper injection technique so that your dog is comfortable and so you aren’t stressed out.
• Keep insulin refrigerated and never use expired insulin.
• After injections check your dog closely for the next few hours, looking for signs of low blood sugar (hypoglycemia).

2. Diet Control

• Feed a consistent balanced diet as advised by your vet
• You are better off choosing a higher fiber, low-fat, low-sugar dog food.
• Avoid table scraps and sugary snacks.
• Meals, which should be a complete meal and not table scraps, should be the same time of day and hopefully before insulin injections so your dog can have normal sugar level before a shot.

3. Regular Exercise

• Exercise every day, in the form of a walk or gentle play, and hopefully more than once a day.
• Keep your exercise routines as consistent as possible as far as timing and intensity.
• Do not engage in sudden activity that may cause your dog’s blood sugar to drop too low.
• Routine exercise will help induce insulin sensitivity and better overall health.

4. Weight Management

• Keep your dog at his or her ideal body weight and if they are obese, work with your designated vet to come up with reasonable weight-loss goals for your dog, as obesity can continue to worsen the disease by making insulin less effective.

5. Blood Glucose Monitoring

• You should consider blood glucose monitoring your dog with a glucometer, or have your veterinarian do it to control diabetes in dogs.
• You should also keep records of your dog’s blood glucose levels, insulin doses, food and activity, etc
• This will help your veterinarian accurately determine the correct dosage of insulin and any treatments administered.

6. Hydration and Urine Monitoring

• Provide fresh water at all times, as diabetic dogs drink more.
• Watch for changes in urination frequency or signs of urinary tract infections.
• Inform your vet if your dog shows signs of infection or discomfort.

7. Routine Veterinary Care

• Routine veterinary appointments should be made for check-ups and lab tests (fructosamine or glucose curves).
• Timely detection and treatment of any infections or complications are very important.
• If you notice any changes in your dog’s behavior or physicality, let your veterinarian know promptly.

8. Stress and Environment Management

• Keep your dog’s environment as calm as possible, and as consistent as possible.
• Stress can adversely affect blood sugar levels and your dog’s general health.
• Make your dog an outdoor and indoors area that is comfortable and loving, to help lower their anxiety.

9. Emergency Preparedness

• Learn the warning signs of hypoglycaemia (weakness, shaking, seizures).
• Keep fast-acting sugar (e.g. honey or syrup) within reach, to treat low blood sugar.
• Keep your veterinarian’s emergency contact information hands.

Potential Complications and Emergency Situations of Diabetes in Dogs-

Complication / Emergency	What It Is (Simple Explanation)	Signs to Watch For	What to Do
Hypoglycemia (Low Blood Sugar)	Blood sugar drops too low, often from too much insulin or missed meals	Weakness, shaking, seizures, collapse, confusion	Give fast-acting sugar (honey or syrup), then visit the vet immediately
Diabetic Ketoacidosis (DKA)	Serious condition when body breaks down fat for energy, producing toxic acids (ketones)	Vomiting, weakness, rapid breathing, dehydration, bad breath	Emergency vet visit — needs immediate treatment and hospitalization
Urinary Tract Infections (UTI)	Infections in the bladder or urinary tract common in diabetic dogs	Frequent urination, straining, blood in urine, foul smell	Vet visit for antibiotics and treatment
Cataracts and Vision Loss	High sugar damages the eyes, causing cloudiness and blindness	Cloudy or white eyes, bumping into objects	Discuss with your vet about treatment options (sometimes surgery)
Pancreatitis	Inflammation of the pancreas, sometimes linked to diabetes	Vomiting, abdominal pain, lethargy	Vet visit for supportive care and treatment
Peripheral Neuropathy (Nerve Damage)	Nerve problems often in back legs causing weakness or limping	Weakness in hind legs, difficulty walking	Talk to your vet about management options
Infections and Poor Healing	Diabetes slows immune response, causing wounds to heal slowly	Cuts or sores that don’t heal, redness, swelling	Seek veterinary care for proper wound management

Hypoglycemia in Dogs-

What is Hypoglycemia?
It is defined as your dog’s blood sugar level being too low, which can lead to your dog being weak, dizzy and shaky.

Why Does Hypoglycemia Occur?
It can occur if your dog receives too much insulin, misses a meal, or exercises too hard without having eaten enough.

Common Signs
Signs of hypoglycemia includes your dog trembling, seeming disoriented or confused, wobbling when walking, appearing sleepy, or at the worst – seizures.

Immediate Steps
Give your dog something sweet like honey or syrup on their gums, and call your vet at once!

Prevention Steps
Feed your dog consistently, administer insulin as directed by the vet, and continue to keep their blood sugar monitored.

Diet Plan for Diabetic Dogs-

Meal Time	What to Feed	Why It’s Good	Tips
Breakfast	High-fiber, low-fat dog food	Helps control blood sugar levels	Feed at the same time every day
Mid-Morning Snack	Small portion of plain cooked veggies (like green beans)	Adds fiber, low in sugar	Avoid starchy or sugary snacks
Lunch (if given)	Balanced diabetic dog food or lean protein (like boiled chicken)	Keeps energy stable	Avoid table scraps or fatty foods
Dinner	Same as breakfast: high-fiber, low-fat dog food	Maintains steady blood sugar overnight	Feed right before insulin injection
Treats	Low-calorie, vet-approved diabetic treats	Won’t spike blood sugar	Limit treats; avoid sugary or fatty ones

---

Special Points-

• Always provide fresh water throughout the day.
• Avoid foods with high sugar or simple carbohydrates.
• Keep meal times consistent to match insulin schedules.
• Consult your vet before changing your dog’s diet.

Foods That Should Be Avoided For Diabetic Dogs

Every pet parent should have knowledge of some specific foods that are not good for diabetic dogs

Food	Reason to Avoid
Sugary Treats & Sweets	Cause blood sugar spikes, making diabetes harder to control
Table Scraps (especially fatty or salty foods)	High in fat and salt, can cause weight gain and upset stomach
White Bread, Rice, and Pasta	Simple carbs that raise blood sugar quickly
Chocolate	Toxic to dogs and can worsen health problems
Grapes and Raisins	Toxic to dogs, can cause kidney failure
Dairy Products	Some dogs are lactose intolerant; can cause digestive upset
Fatty Meats and Fried Foods	Can lead to obesity and pancreatitis, complicating diabetes
Onions and Garlic	Toxic to dogs and can damage red blood cells

Can Diabetes in Dogs Be Reversed?

• In most cases, diabetes in dogs cannot be completely reversed. It’s usually regarded as a chronic disease that requires ongoing management.
• However, early diagnosis and good management (for example, with insulin, diet, and exercise) has enabled some dogs to live healthy and happy lives.
• In very rare instances, it is possible that some mild forms of diabetes due to temporary problems (for example, pancreatitis) can improve if diagnosed very early on, however this is nothing to get your hopes up over.
• The goal is to ensure the dog has good blood sugar control so we can prevent complications from the disease, and allow the dog to remain symptom free for longer.
• Overall, the most important thing you can do for your dog is to work with your veterinarian for your dog’s benefit, on ongoing adjustments to treatment, and for the dog to receive best possible care.

FAQs-

1. Insulin used for diabetes in dogs is same as human or different?

Insulin used to treat diabetes in dogs and humans can be the same in some cases, but there are also formulations specifically designed for veterinary use.

Insulins Used in Both Dogs and Humans:

1. NPH insulin (Isophane insulin)
   • Brand example: Humulin N, Novolin N
   • Used in both humans and dogs
   • Intermediate-acting
2. Lente insulin
   • Brand example: Vetsulin (also called Caninsulin in some countries) used for diabetes in dogs.
   • Approved for veterinary use, but derived from pork insulin, which is very close to canine insulin (differ by only one amino acid)
   • Often preferred in dogs for its duration and compatibility
3. Detemir insulin (Levemir)
   • Long-acting insulin used in humans
   • Can be used in dogs but requires very low doses due to dogs’ high sensitivity to it
4. Glargine insulin (Lantus, Basaglar)
   • Long-acting, used more often in cats, but can be used in dogs in select cases

---

Main Differences Of Insulin to Consider–

• Concentration:
  • Human insulin is usually U-100 (100 units/mL)
  • Vetsulin is U-40 (40 units/mL), so syringes must match to avoid dosing errors
• Species-specific responses:
  • Dogs may metabolize insulin differently than humans
  • Insulin duration and peak times can vary

2. How Many Years A Dog Can Survive With Diabetes?

After diagnosis, a dog with diabetes can survive many years(often 2 to 5 years or more) provided the disease is well-managed by good management ,exercise and diet.

3.What food causes diabetes in dogs?

Diabetes in dogs is not usually caused by a specific food, but rather by a combination of factors, including genetics, obesity, age, and hormonal imbalances. However, diet can contribute to the risk—especially if it leads to excess weight gain or insulin resistance.

High-fat diets

High-calorie diets

Sugary human foods

Low-quality commercial dog foods

Frequent table scraps

4.Can diabetes cause seizures in dogs?

Yes, diabetes can cause seizures in dogs, but indirectly—seizures are not a common direct symptom of diabetes. When seizures do happen in a diabetic dog, they are usually due to:

---

1. Hypoglycemia (Low Blood Sugar)

• The most common cause of seizures in diabetic dogs.
• Happens if:
  • Too much insulin is given
  • The dog doesn’t eat after insulin
  • There’s too much exercise without food adjustment
• Brain cells need glucose; without it, seizures, collapse, or coma can occur.

---

2. Diabetic Ketoacidosis (DKA)

• A serious complication of uncontrolled diabetes
• Causes:
  • Dehydration
  • Electrolyte imbalances
  • Acidosis (blood becomes too acidic)
• In severe cases, it can lead to neurological signs, including seizures.

---

3. Hyperosmolar Hyperglycemic State (HHS)

• Rare but life-threatening condition
• Blood sugar becomes extremely high
• Causes dehydration and brain swelling, which may lead to seizures

---

4. Secondary Conditions

• Diabetes can increase the risk of other conditions (e.g., high blood pressure, liver disease) that can trigger seizures.
