The endocrine system interacts with many organs and bodily systems, and the adrenal and thyroid glands play a major role in providing critical trace nutrient support to all glands and tissue. The adrenals can become stressed and fatigued, negatively impacting the liver, duodenum, and kidneys.

Iodine is a natural chemical required by our dogs and cats to survive and is also a necessary component for thyroid hormones. The thyroid gland is located in the base of the neck, and produces hormones which help regulate metabolic processes such as growth and energy expenditure. When thyroid hormones are imbalanced, health conditions can present. 

The main cause of iodine deficiency is lack of iodine in the diet. Most commercial dog and cat foods contain adequate levels of iodine, however, how each animal processes iodine varies. Supplementing your pet's diet with critical trace micro and macro-minerals and green leafy vegetables is recommended.

Hypothyroidism

Hypothyroidism is the most common hormonal disorder in dogs. It most commonly affects neutered male and spayed female dogs between the ages of 4 and 10 years.  Hypothyroidism develops when there is a deficiency of hormones thyroxine (T4) and tri-iodothyronine (T3).

The exact cause is unknown but it may be caused by an auto-immune response in which the dog’s own immune system kills cells of the thyroid gland. Dogs that usually suffer from recurring skin problems may be exhibiting symptoms of hypothyroidism.

Symptoms of hypothyroidism in dogs associated with low iodine levels include:

Poor growth

Hair loss

Weight gain in older animals

Weakness

Behavioral changes

Irritability

Lethargy

Lack of interest in play

Increased amounts of sleeping

Depression

Weight gain (without an apparent increase in appetite)

Obesity

Cold intolerance  (your dog may seek warm places to help address low body temperature)

Slow heart rate (bradycardia)

Infertility

Constipation

Diarrhea

Chronic skin disorders (dry skin, thinning of the hair coat)

Certain dog breeds seem to be more predisposed to hypothyroidism than others. This disorder typically affects mid to large size breeds such as Dobermans, Golden Retrievers, Dachshunds, Miniature Schnauzers, Cocker Spaniels and Airedale Terriers.

There is no cure for hypothyroidism but with treatment, pets can continue to enjoy good quality of life. 

Hyperthyroidism

Hyperthyroidism is a common endocrine disorder in cats when an excess amount of hormones are produced by the thyroid gland. Hyperthyroidism is rarely seen in dogs.

Symptoms of Hyperthyroidism often include:

Polydipsia (Excessive drinking)

Polyuria (Excessive urination)

Polyphagia (Excessive appetite)

Weight loss

Hyperactivity

Irritability

Aggression

Vomiting

Diarrhea

Voluminous fatty feces

Heat intolerance

Panting

Skin lesions, dry, greasy, matted coat, alopecia

Studies suggest that cats fed a canned commercial food (grocery store brands) are more at risk from hyperthyroidism (this may because of substances in the lining of the can or because of iodine levels). Switching brands of canned foods (including flavors in the same brand) can overwhelm the system and induce hyperthyroidism so switching brands too frequently should be restricted.

Helpful suggestions: 

Feed your pet a natural, raw and well balanced diet that contains all the essential vitamins, minerals and nutrients

Incorporate small amounts of kelp (Yelp for Kelp) to prevent deficiencies in thyroid health

Ensure that your pet gets regular exercise

Boost your dog or cat’s immune system with immune-boosting supplements

Take your pet to the vet for annual check-ups and monitor any abnormal physical and behavioral changes

If your pet suffers from a thyroid problem, become as knowledgeable as possible about this health problem

Conventional Remedies:

Your will will perform a thorough physical exam, document clinical signs, and will likely run the following diagnostic tests to assess organ function, including:

Complete blood count (CBC)

Biochemical profile

Urinalysis

Thyroxine (T4) level, free-T4 level

Canine TSH test

Thoracic (chest) and abdominal radiographs (X-rays) in certain cases

Many other diseases of older cats can mimic the symptoms of hyperthyroidism, including diabetes mellitus and IBD.

Fortunately, hypothyroidism is easily treated and involves the administration of daily doses of synthetic thyroxine. It is usually required for the rest of the dog’s life.

For cats, a Thyroidectomy may be required in more serious cases, and involves removal of the thyroid glands, however, the operation itself may be risky because of the use of anesthetic with cardiac, renal, hepatic and gastrointestinal problems.
