2. Causes:

>2. Causes: 5 kinds of causes that can lead to obesity.

A. Depending On The Dog’s Environment:

overfeeding a dog
  • Overfeeding the dog or feeding it whenever it asks for or feeding it junk food can lead to obesity.

We the owners get too sweet with our pets and forget that sometimes saying no to it can save it from a lot of many troubles.

  • Apart from eating more than what it needs, not looking after your dog’s need for exercise can make it lazy and resistant to going outside and playing.

This can decrease its stamina over time and make it lethargic.

This less expenditure and a good intake of energy can lead to an undue gain in the weight of the dog.

  • One of the major problems nowadays is that the owners don’t seem to acknowledge that there is a problem.

This seems to give away to more weight gain and worsen the situation.

B. Depending On The Physiology Of The Dog:

Depending On The Physiology Of The Dog
  • As a dog’s age, their metabolism gets slow and also their ability to remain active goes down, making them prone to obesity.

This generally happens after the age of 5 and so you should make changes in its diet and exercise routine in accordance with the consult of a veterinarian.

  • An overweight dog can be overweight because it is genetically predisposed to gain or retain weight.

There are many breeds that are prone to obesity and we will talk about them further in this article.

C. Depending On Any Past Surgery Or Medications:

Depending On Any Past Surgery Or Medications
  • Surgeries like neutering or spaying can disturb the balance of hormones including sex hormones in a dog which can further cause the lowering of its physical activity and over that it can make your dog feel hungry most of the time.
  • Some prescriptions of drugs have their side effects and one of them can be gain in weight.

Medications for anticonvulsant can lead to an increase in hunger of the dog.

Medications like glucocorticoids can abnormal fat depositions and weight gain.

D. Depending On Past Or Present Diseases:

  • There are many diseases that contribute to weight gain as an after effect or its symptoms.

Hypothyroidism in dogs, for example, is a disease in which the immune system starts attacking the thyroid gland and this causes an imbalance of hormones leading to undue weight gain.

  • Insulinoma is a condition in which there are cancer cell growth in the pancreas and can reduce the amount of glucose in the cells of a dogs body and also increase the secretion of insulin in the bloodstream.

This can cause weight gain in dogs.

  • Cushing’s disease or hyperadrenocorticism is a disease that can cause an increase in hunger and also cause pain in various parts of the body preventing your dog from much needed physical activities and consequently causing obesity.

3. Consequences of Obes>3. Consequences of Obesity:

Consequences of Obesity

To many, obesity doesn’t seem like a big issue and hearing things like ‘shortens the lifespan’ or ‘puts pressure on the heart’ don’t sound alarming but if you love your pet and want it to stay healthy and active throughout its time with you, then start taking obesity as a serious concern as it can do a lot more damage than you think.

It causes overweight dog problems like –

A. Weakening Of Joints, Bones, And Ligaments:

An Overweight dog will have an extra strain on their bones and joints while walking or doing any exercise.

This can over time cause weakening of the ligaments due to the pressure on the joints and also cause pain in the knees, hips or shoulders.

This can make the bones brittle with time and more prone to hip dysplasia and ligament tears.

B. Diabetes Mellitus:

An obese dog has more tissue than required and so the body needs to secrete more insulin also so as to counter the increased blood glucose level.

When the need for insulin exceeds the ability of the body to produce insulin, diabetes mellitus develops.

It can put so much pressure on the pancreatic cells to produce insulin that the cells can burn out resulting again in diabetes.

C. Heart disease and High Blood Pressure:

Obesity can lead to hypertension which is due to increased blood pressure.

Also, it puts a lot of strain on the heart as the heart has to work harder to make the blood reach the extra tissues.

This can be strenuous for the heart and this for a long term can lead to congestive heart failure.

D. Difficulty in Breathing:

difficulty in breathing in dogs

In obese dogs, there is so much amount of fat that there is no space for the lungs to expand and over that due to the presence of extra tissues, the lungs have to work harder to provide oxygen to these tissues making the situation worse.

The dogs who over obesity have respiratory disorders can suffer badly.

E. Decreased Stamina:

Naturally, when it gets difficult for the heart and lungs to function properly, the dog gets lethargic and lazy.

The dog can be found breathing heavily after a normal walk outdoors and can no longer cover good numbers in lengths as it used to.

F. Intolerance Towards Hot Weather:

Obesity means an increase in the body fat which counts well in insulating the dog from cold but when it comes to summers, it is completely the opposite and can make it hard for the dog’s body to cool down under hot weather conditions.

G. Decrease In The Functioning Of The Liver:

The function of a liver is to store fat but in the case of an overweight dog, the liver has fat stored in excess which can lead to a condition called hepatic lipidosis which can lower the functioning of the liver.

H. Increased Anesthetic Risk:

Inducing anesthesia in an obese dog has the risk factor of getting a cardiac arrest.

It lowers the blood pressure so much that it gets difficult for the blood to reach the extra tissues.

Anesthesia is absorbed by fat present in the body and so an obese dog can take longer to come out of its effects also due to the fact that the liver, which is responsible for breaking down the effects of anesthesia is not effectively functional.

I. Reproductive Problems:

Fat dogs have difficulty in giving birth and may require a c-section to be performed by the veterinarian as assistance.

This condition of difficulty in giving birth is called dystocia.

J. Digestive Disorders:

Indigestion is common among overweight dogs and can lead to constipation and intestinal problems, stomach ulcers and if this goes on for long, it can also cause intestinal cancer.

K. Prone To Cancer:

Any dog that has been through or is going through obesity is prone to develop cancer and mostly that of the urinary bladder.

L. Decreased Immunity:

Obesity also lowers the immunity of the dog and leaves it vulnerable to many diseases or it can lead a common disease into becoming a major one.

M. It’s Hard On The Owner’s Pocket:

As a dog becomes obese, its demands in various aspects increase.

Its need for food to satisfy its undue hunger increases and with that increases the need to consult a vet.

To remedy it from obesity, you and your vet have to keep a track of the dog’s activity and diet and to consult a vet is a costly affair.

Over that, it takes months for a dog to lean down which means a lot of visits to the vet.

If medications are prescribed then the drug costs and if certain training is prescribed then even that costs.

Over that, it becomes a continuous run behind your dog to make it lean again.

N. Osteoarthritis:

Osteoarthritis is a common disease in overweight dogs as it is caused due long term excessive pressure on the joints which deteriorates the ligaments and so causes pain and can make a dog reluctant to walk.

This can be severe obesity in a dog.

O. Skin Diseases:

skin diseases in dogs

An obese dog is hard to groom as its skin gets thick and coat gets hard.

Not getting rightly groomed leads to bacterial growth and infection.

Hard skin coat when groomed hard can get scratches and cuts which can develop infections.

There are many skin folds on an obese dog that can accumulate oil and sweat, becoming prone to infections.

FACT-ILICIOUS: “According to the Purina Lifespan Study, obesity takes almost two years off a dog’s life.”

“The five US states that rank highest for obese dogs are: Minnesota, Nebraska, Michigan, Idaho, and Nevada.”.

4. Diagnosis:
