How does diabetes start?

Before knowing how to prevent diabetes you must know how it starts. There is a hormone called insulin which is produced by the pancreas in the body. Insulin is responsible to aid the body in converting glucose into energy. The body uses this energy to do functioning. When due to any reason the pancreas is unable to produce this hormone, body functions get disturbed.

As glucose is not converted into energy, it stays in the bloodstream. The glucose level rises in blood and does damage to the body. In simple words, this whole disturbance in insulin production is called diabetes.

If not managed properly diabetes can even turn fatal for your dog. The high blood glucose level can cause the body’s functions to shut down. As a result, the dog can go into a coma or even die if not treated on time.


How do dogs get diabetes?

Several internal and external factors can lead to diabetes. These are

Hereditary factors

Diabetes could be hereditary. If the pup’s parents were diabetic, most probably the puppy will get diabetes at some point in life. It’s important to adopt prevention strategies because such puppies are more prone to become diabetic.

Autoimmune system

Some puppies are genetically born with the defected immune systems. Their own body cells destroy the insulin hormones which alter body functions and cause diabetes.

Bad health

Many infections and illnesses,  if not treated on time can lead to diabetes. Viral or bacterial infections can also end up in diabetes.

Hormonal issues

Messed-up hormone levels in the body can affect glucose levels. This is a leading factor causing diabetes in dogs. Both physical and emotional reasons can change hormone production in the body.


Obesity is another major factor of diabetes in dogs. Certain breeds are more prone to become obese and diabetic. Especially toy breeds who spend more time in owner’s laps or cuddling on the couch (also read do huskies like to cuddle)

Dogs who live indoors have less chance to move around. If they get obese they have pretty much a chance to end up diabetic.


Another reason,  your dog can become diabetic is malnutrition. Sometimes owners feed their puppies well but they don’t know that they are missing important nutrients in their diet.

Make a proper routine

Following a Routine can save your dog a lot of trouble. If your dog is in habit of eating,  sleeping, and playing on time,  he will stay fit. Also,  irregularities in the normal routine can cause many problems like

  • upset stomach (read dog diarrhea at night only)
  • bloating
  • lack of sleep
  • Less physical activities etc.

Your dog should get proper time to rest and sleep. Also following the proper eating timetable will improve overall gut and stomach health.

Keep your dog hydrated

Always keep your dog hydrated. Hydration has a strong connection with diabetes. Balance in fluids and electrolytes keeps the body strong. Dehydration makes the body weak and unable to resist or fight diseases.

Also, dehydration can cause infection in the kidneys, and kidney infections are directly related to the cause of diabetes.

Exercise time

Physical activities are vital. It doesn’t matter if your dog lives indoors or outdoors,  you must set up a routine for physical exercise. (Read can huskies sleep outside in cold weather).

Take your dog for a minimum30 min walk daily. (The time depends on the dog’s breed and their need for physical exercise too).

Proper exercise will prevent your dog from getting obese. Obesity can cause other problems too like heart diseases and joint problems in dogs. In general, your dog should stay in shape.

Regular Vet visits

Always take your dog for a routine checkup. Many issues may seem harmless but your dog can end up getting diabetes. Regular checkups will help to keep tabs on your dog’s general health.

If your pup’s parents were diabetic, regular vet visits will be of great advantage. Also, regular checkups can rule out the possibility of genetic disorders.

Get your female dogs spayed

Dogs who are sexually more active are more at risk of getting diabetes. More than half the number of dogs that get diabetes are females. Why?  Because

  • Females dogs can get gestational diabetes when they are pregnant.
  • Getting pregnant again and again also deteriorates the health of female dogs.
  • Non-neutered dogs are more at risk of getting sexually transmitted diseases.

So it’s better to get your dogs spayed. (Also read swollen sacks after neutering and dog in pain after glands expressed)

  • Give him unconditional love.
  • Your dog must feel safe with you.
  • Don’t leave your dog unattended for long periods.
  • Train him well to get socialized. This also improves confidence in puppies.
  • Don’t force him to leave when he doesn’t want to.

  • Use positive reinforcements while training.
