The thyroid hormone can affect almost every function in the body. Ensure that your basenji is tested properly and has the symptoms of true hypothroidism before supplementation.
Are Thyroid Supplements Needed?
It's important to distinguish hypothyroidism from a low
T4. A low T4 may be caused by sickness or stress. Once you
start supplementing, the dog's own thyroid glands may
shut down and atrophy.
Thyroid Testing
The test for TSH concentration became available February, 1995, at
the Animal Health Diagnostic Laboratories--the prestigious laboratories
of the Michigan State University.
