As dogs age, there is a gradual decrease in the production of the thyroid hormone known as thyroxine. If a less than adequate amount of thyroxine is produced, hypothyroidism can result. Detecting hypothyroidism can sometimes be difficult as the symptoms may not be obvious or may appear to be connected with the normal aging process. Symptoms may include the following: chronic skin infections; decreased mental sharpness; delayed hair regrowth; frequent ear infections; itching; lethargy; obesity; personality changes; poor wound healing; reduced exercise tolerance; thinning hair; and neuromuscular system abnormalities like gait abnormalities, occasional gastrointestinal problems and weakness.
Blood tests can be performed to diagnose hypothyroidism. Though treatment of hypothyroidism must be maintained for the rest of your dog's life, it isn't difficult and your dog's prognosis can be excellent. A thyroid hormone supplement is usually prescribed. It's also important that your dog be seen by your vet about every six months. |
