When to Put a Diabetic Dog Down? (Expert Advice!)

A dog is a man’s best friend, don’t they all say? Why? Because in this selfish world, a dog is the only loyal companion that a man can have as an absolute partner that’ll never cheat on or reject.

We love our pooches unconditionally. From entertainment to absolute loyalty, our furry companions have always proved their friendship to us. They remain our side all life long. And as dog owners, our duty to them is to ensure their happiness and wellbeing. Protecting them from any kind of pain as far as possible.

Accepting that your dog has diabetes can be baffling for dog owners. Unfortunately, acceptance is the first step to let go, and you have to at some point. There will be a time when we can do almost nothing to save our pooch from getting hurt and miserable. Controlling the disease gets impossible and a failure each time we try. At this point, euthanasia is the best choice and should be considered for your furry companion. It is only for the best welfare of your dog.

Diabetes Mellitus in Dogs And its Effects

Diabetes Mellitus in Dogs and its Effects

Diabetes comes under the metabolic diseases that affect the way your dog’s body uses and stores sugar (glucose). The most common form of diabetes in dogs is called insulin-dependent diabetes mellitus IDDM), which means that your dog has to take insulin to control his blood glucose levels.

Glucose supplies energy to your furry friend’s body, which is vital. From metabolism to muscle contraction, your dog needs the energy to function properly. When the glucose cannot convert into energy, which happens when there’s not enough insulin, it remains in the blood.

When this occurs, it leaves your pooch in a state of “starvation.” Their body fails to use glucose, which results in a breakdown of fats for energy with some major effects.

Diabetes can leave your furry companion exhausted, and their health eventually worsens. Despite being a treatable condition, there will be a point where nothing can be done to control it, which is excruciating for your dog.

Life With a Diabetic Dog

Life With a Diabetic Dog

A diabetic dog’s life requires few adjustments as its condition keeps worsening. And dogs require us to take care of their day-to-day conditions.

First, your dog needs to be supplied and administered a twice-daily dose of insulin as its body fails to produce it. Your veterinarian should demonstrate the right technique for doing this before your dog begins its diabetic treatment.

Exercising regularly is very crucial for keeping your furry companion active and in proper shape. Because working out will help lower blood sugar to use up energy. However, be cautious not to exaggerate as too little glucose in the blood might lead to difficulties of its own.

Diet has a consequential role in your dog’s condition. There are diabetes-specific foods available for your furry companion that are high in fiber and low in fat. Foods high in fiber take longer to digest and slow the absorption of carbohydrates. A diabetic dog may experience hazardous blood sugar swings.

Make sure to visit your vet to manage your dog’s health. Routine blood checkup is necessary to ensure diabetes is under control.

Treating a diabetic dog is not cheap, but also there are no shortcuts. It may happen that you’re not able to afford the cost of their treatment, which may leave your dog’s diabetes unchecked. Therefore, you must make a deliberate decision to euthanize sooner.

To understand how they might be suffering. Here is an example of a dog named Lucy

Two years ago, a dog named Lucy, who was once a happy furry companion, was diagnosed with diabetes 2 years ago. Her condition was in control with the help of insulin injections. But, the disease started to progress with time as she aged which made the doses of insulin less and less efficient.

The miserable pooch started to develop urinary tract infections as her blood sugar started to get out of control because of glucose passing in her urine.

Increasing the doses was the first thing by her vet, and the type of insulin was changed. Despite doing everything, all attempts at helping her failed. She wasn’t the same Lucy as she was before, happy and bouncy.

After a long, painful decision, it came to euthanize Lucy as she was miserable. Keeping her alive would be a very selfish thing to do while every day she is in pain. Lucy was not enjoying her life anymore.

Indeed, that was a decision not for everyone to make. But a decision that was best for Lucy, no longer hurting and miserable than once she used to be.

The Final Stages of Dog Diabetes

Although diabetes can be controlled to a certain extent, your dog’s insulin injections will probably start to have an impact at some point. Your dog has a lower quality of life because of increased urine output, weight-loss, thirst and vomiting.

Ketoacidosis is a state where your dog may enter ‌its final stage of diabetes. It is life-threatening, and chances are your dog may not survive.
