Abstract Hypothyroidism is recognised as an important endocrine disorder of dogs, and a frequent differential for numerous presenting complaints. Its diagnosis has never been straight forward as results suggestive of hypothyroidism can occur for a variety of reasons in dogs with normal thyroid function (euthyroid). As a consequence, the accurate investigation of hypothyroidism has been hindered by the potential inclusion of a number of cases not truly hypothyroid. In recent years, the… 

Hypothyroidism in dogs: laboratory findings

The most commonly used criteria to diagnose hypothyroidism are decreased total thyroxine (TT4) or free thyroxines (FT4) in combination with increased thyroid-stimulating hormone (TSH) concentration.

Canine Hypothyroidism: A Review and Recent Advances in Management

Hypothyroidism is most often diagnosed in middle-aged dogs (approximately 7-8 years old) and is more likely in pure breeds, however Golden Retrievers, Doberman Pinschers, Labradors and Cocker Spaniels are predisposed.

Congenital hypothyroidism of dogs and cats: A review

Adequate replacement therapy results in a successful outcome in the majority of cases, especially when started early in life, as permanent developmental abnormalities can be prevented.

Hypothyroidism in dogs: pathophysiology, causes and clinical presentation

Hypothyroidism is the most common endocrine disorder in dogs, resulting from primary thyroid gland failure associated with either lymphocytic thyroiditis or idiopathic follicular atrophy, both of which occur at approximately equal frequency.

Neurologic manifestations of hypothyroidism in dogs.

Several neurologic manifestations of primary hypothyroidism in dogs are described; the pathophysiology of hypothy thyroid disease-induced neurologic disorders affecting the peripheral and central nervous systems are discussed; and the evidence for the neurologic effects of hyp Timothyroidism is reviewed.

Spontaneous primary hypothyroidism in 7 adult cats

Most cats appear to develop a goitrous form of hypothyroidism associated with thyroid hyperplasia, whereas thyroid atrophy appears to be less common.

Facial Paralysis Secondary to Hypothyroidism in a Dog

The diagnosis of facial paralysis associated with hypothyroidism was based on the history, clinical and neurological examination findings, laboratory assessment of thyroid function by observing low serum free T4 and high concentrations of TSH, the therapeutic response after supplementation levothyroxine sodium, and exclusion of other pos­sible causes.

A case of hypothyroidism concurrent with myxedema coma in a Cocker spaniel dog

The clinical features and successful treatment of a Cocker spaniel dog with concurrent hypothyroidism and myxedema coma and gallbladder mucocele is described.

The Role of Hypothyroidism in the Etiology and Progression of Dilated Cardiomyopathy in Doberman Pinschers

This study did not confirm a role of hypothyroidism in the etiology or progression of DCM, but there was a progression of the heart disease despite optimal thyroid treatment of dogs with hypothyroxine and DCM.

Euthyroid Sick Syndrome and Changes in Thyroid Hormones in Dogs with Hemoparasitosis

This is the first study to provide evidence on the existence of euthyroid sick syndrome in dogs with hemoparasitoses in Brazil, including dogs simultaneously infected by E. canis and Babesia canis vogeli and/or Anaplasma platys before and after treatment with doxycycline chlorohydrate.



Etiopathologic findings of canine hypothyroidism.

Epidemiological, clinical, haematological and biochemical characteristics of canine hypothyroidism

Assessment of cholesterol, creatine kinase, aspartate aminotransferase, γ-glutamyltransferase, and red blood cell and neutrophil counts may be particularly useful in distinguishing hypothyroid dogs from euthyroid animals with similar clinical signs.

A continuous decrease of thyroid volume was seen over time after treatment, while the other investigated parameters did not change significantly during the follow-up period.

Tertiary hypothyroidism in a dog

A nine-year-old male entire Labrador was diagnosed with pituitary dependent hyperadrenocorticism and tertiary hypothyroidism was made, which has not been previously reported in dogs.

Canine serum thyroglobulin autoantibodies in health, hypothyroidism and non-thyroidal illness.

Thyroglobulin autoantibody was positive in 43 per cent of hypothyroid dogs with unexpectedly normal serum c TSH concentrations and was particularly useful in the classification of these cases.

Neutering was determined to be the most significant gender-associated risk factor for development of hypothyroidism and those with severe concurrent disease or neurologic abnormalities were less likely to respond with complete resolution of clinical signs.

Hypothyroid-associated central vestibular disease in 10 dogs: 1999-2005.

Although the pathogenesis in dogs without evidence of infarction is unknown, central vestibular dysfunction appears to be a rare but reversible neurologic sequelae of hypothyroidism.

Neurological manifestations of hypothyroidism: a retrospective study of 29 dogs.

Neuromuscular signs in association with hypothyroidism are described in 29 dogs, and dogs with vestibular deficits had abnormal brainstem auditory-evoked responses (BAER), including increased latencies of P1-P6 and decreased amplitude of P4,5-N5.

Thyroid function and infertility in the dog: a survey in five breeds.

Thyroxine and thyroid-stimulating hormone plasma concentrations were assayed in order to assess the real incidence of hypothyroidism associated with reproductive disease in dogs of five different breeds and found the same tendency in bitches.

Endogenous TSH in the diagnosis of hypothyroidism in dogs.

Measurement of canine thyrotropin (cTSH) has an excellent specificity and is a valuable tool in confirming canine hypothyroidism, but due to the low sensitivity of cTSH assays it can not be recommended to exclude the disease.
