Hypothyroidism (Underactive Thyroid Gland) in Dogs

Animals Affected

Hypothyroidism is common in middle-aged and older dogs.

Overview

Hypothyroidism is a disease of the thyroid gland. The thyroid gland, located in the neck, produces a hormone called thyroid hormone. Although thyroid hormone plays a complex role in the body, its main effect is to increase the rate of metabolism. Hypothyroidism causes reduced production of thyroid hormone. Therefore, the main problem in hypothyroidism is reduced metabolism.

FIC/FLUTD/FUS(Urinary Tract Irritation in Cats)

Animals Affected

Cats

Overview

FIC, FLUTD, and FUS are synonyms for a painful syndrome in cats. FIC is currently the most commonly used name. Its symptoms, listed below, mimic those of bladder infections. FIC is characterized by inflammation of the bladder and urinary tract which can be chronic or recurrent. The urine of these cats often is very strong, and may have an abnormal pH. As well, the syndrome has been correlated with crystals in the urine.

Feline Urinary Obstruction

Animals Affected

Male cats

Overview

Feline urinary obstruction is a life-threatening medical emergency.  It occurs when a plug of mucus or a small stone lodges in the urethra and obstructs it.  Strong spasms of the urethra may contribute to the syndrome.  Because the urethra is the structure used to drain urine from the bladder, this situation makes urination very difficult or impossible.
