Our dogs share a lot of common ailments with us, and one of them is hypothyroidism. Most of us are familiar with “thyroid problems,” in that we hear the phrase spoken around us. But if you do not understand the disease and the symptoms, it’s possible your own dog could be suffering from it and you would not even know.
What it is.
Hypothyroidism is an endocrine disorder that is caused when the thyroid gland does not produce enough hormones (specifically T3 levothyroxine and T4 levothyroxine). (www.petmd.com) The
disease is easily treated, but because the symptoms are so wide spread, many pet owners do not think about checking it until all other possibilities are ruled out. If left untreated, it can lead to Cushing’s disease, another endocrine disorder affecting the pituitary gland.

If your dog is only exhibiting the milder symptoms, you may attribute the problems to poor diet, boredom, personality, etc. For example if your dog just seems lethargic and “dull,” you might think that your dog is bored or not very bright. It may never cross your mind that something is wrong with them physically.
Veterinarians are not a hundred percent sure what causes Hypothyroidism. It may be linked to an autoimmune disorder, cancer, congenital disease, iodine deficiency, or an after-effect of a medical treatment (like surgery) (www.petmd.com).
