You should seek the advice of your veterinarian if your pet is ill as only he or she can correctly advise on the diagnosis and recommend the treatment that is most appropriate for your pet.

Hypothyroidism is one of the most common endocrinopathies in dogs, and it is well known as "the great impersonator" because it can manifest itself as a wide range of non-specific clinical signs. However, routine screening for hypothyroidism is not always practiced when a clinician is presented with an apparently primary disorder - which may in fact be secondary to hypothyroidism.

The following alphabetical list contains some of the clinical conditions for which it has been reported that hypothyroidism may be an underlying cause, and in which routine screening for hypothyroidism should be performed. 

Provet is conducting an independent survey into the relationship between these conditions and hypothyroidism, so please let us know if you confirm the presence of hypothyroidism in association with any of the following problems, and let us know whether the patient exhibited any other concurrent clinical signs :

  • Abortion
  • Alopecia (bilateral and non-pruritic)
  • Atherosclerosis
  • Bradycardia
  • Bruising following minor trauma
  • Constipation
  • Corneal ulceration
  • Dry eye (keratoconjunctivitis sicca)
  • Exercise intolerance
  • Fading puppy syndrome
  • Hyperpigmentation of the skin
  • Hypothermia
  • Infertility problems
  • Lactation (abnormal - not associated with pregnancy) and breast enlargement
  • Laryngeal paralysis
  • Lipidosis of the cornea
  • Myopathy - generalised muscle weakness
  • Nails - excessive wearing of the tops of the nails
  • Oestrus irregularities
  • Pyoderma
  • Seborrhoea
  • Testicular atrophy
  • Uveitis
  • Weight gain
  • Poor wound healing
