The pituitary is known as the "master gland" because it controls so many hormone functions. Among other things, it produces thyroid stimulating hormone, or TSH, which causes the thyroid gland to release T4.Regular testing should be done after treatment to monitor the thyroid levels and/or any tumors or abnormal tissues. Tumors Tumor removal depends on a variety of factors. The size of the tumor, its proximity to the esophagus and major arteries, and if its benign or malignant will help your vet determine the best course of.
Falsely low thyroid hormone levels can be due to administration of steroids ( cortisone -like medications ) or concurrent systemic disease. A TSH stimulation test can be run if the diagnosis is in doubt.By: Tony Alter To diagnose thyroid conditions in your dog, many tests may be performed together or independently by your vet. Tests to determine the level of thyroid hormone are the most common, but others may be necessary to evaluate tumors or abnormal thyroid tissues.
Some veterinarians include portions of this test on their yearly blood screens.( ref ) In dogs with this disease, blood entering the syringe is often creamy whitish in color due to the presence of large amounts of fats ( triglycerides and cholesterol ).The most important test is the pet's Free T-4 ( free thyroxine ) level - the level of active thyroxine in their blood. How Did My Dog Become Hypothyroid? Most cases of hypothyroidism are caused by the dogs own immune system attacking its own thyroid gland tissue.

Hypothyroid dogs commonly have excess black pigment in the skin of their groin.Hyperthyroidism This condition occurs when the thyroid levels are too high or when too much levothyroxine has been consumed. Treatment options include radioactive iodine (facilities may be limited chemotherapy, radiotherapy or anti-thyroid medication.
Return to Top of Page Potential Causes Is your dog at risk? While some breeds appear predisposed to hypothyroidism, statistics pertaining to age, sex, and neutering contradict each other. Many experts agree that the incidence of canine hypothyroidism is increasing and that this condition, normally associated with middle-aged and older dogs, is becoming more common.It is safe to say that hypothyroidism can affect any dog (male, female, spayed, neutered, or intact) of any breed at any age. Breeds with a definite predisposition to develop hypothyroidism include: Boxer.
But when an animals backs become flattened instead of curved and they huff and puff with every exertion some owners bring them in for a check up. When owners bring me these pets, I run thyroid tests on all of them.The hormones produced by this gland regulate several bodily processes, and changes in the amount of hormones produced can create endocrine conditions in dogs. You may be aware of these conditions because they also affect humans.
Dogs may have a low or high total T4 but a normal free T4, so its important to run this test in addition to the others. TSH: Thyroid-stimulating hormones are measured by this test, but it has a high probability of inaccurate results (false positives, false negatives).Return to Top of Page Signs of hypothyroidism Because hypothyroidism affects many body systems, clinical signs are variable, non-specific, and often slow to develop. The most classic signs (significant weight gain, lethargy, and cold intolerance) do not appear until more than 70 percent of the thyroid gland is destroyed.
(This is the same medication I have taken since my thyroid was removed.) Levothyroxine is generally inexpensive and can be administered in tablet or liquid form. The medication is best taken on an empty stomach to ensure optimal absorption.In dogs, about half of the bodys T3 comes from the thyroid gland and about half is converted from T4 by other tissues. The production of T4 is regulated by the pituitary, a tiny pea-sized gland at the base of the skull.
See the following for more information (most of which is human-oriented, unfortunately The Renal Manifestations of Thyroid Disease. In experimental animals, the availability of thyroid hormone affects kidney size, weight, and structure both during development and in adults.Do not add kelp to a commercial diet that already contains iodine.

In humans and dogs, hypothyroidism is the most common endocrine disorder; cats and a smaller percentage of humans are prone to hyper thyroidism, an overactive thyroid gland.
Secondary hypothyroidism develops when some other influence causes the thyroid gland to produce insufficient thyroxine, such as when a brain disease interferes with the regulation of thyroid gland activity, or when the gland is destroyed by radiation therapy, surgical removal, or the administration of medications that affect thyroid gland activity.Alternatively, the same is true for a dog with hyperthyroidism given too much anti-thyroid medication or as a result of any procedures done to reduce thyroid hormone production. Administer medications as accurately as possible.
