Carroll County Animal Hospital

HYPOTHYROIDISM

HISTORY:

Red, a 7 year old female spayed Chesapeake Bay retriever, presented to Carroll County Animal Hospital for severe lethargy (no energy, laying around), weight gain, and urinating inappropriately in the house. On examination, Red had a normal body temperature and heart rate. She was panting excessively on examination. Red was severely obese with a body condition score of 9/9. During examination, Red was dribbling urine from her vaginal area. Palpation of her abdomen revealed no pain or signs of bladder stones.
She is on a premium adult dry dog food and is given heartworm and flea prevention monthly.

DIAGNOSTIC TESTS:
It was then recommended that Red have a urine sample analyzed and a full panel of blood work performed including complete blood count, chemistry profile, and thyroid hormone testing.

Complete Blood Count: Normal
Chemistry Profile: Mildly elevated Cholestrol (Normal kidney, liver, and pancreas enzymes)
Urinalysis: Large amounts of proteins, white blood cells, and blood.
Thyroid Profile: Severely decreased T4 of 0.4 ug/dL (Normal range is 1.0-4.0 ug/dL)

ASSESSMENT:
Red has a urinary infection (blood and white blood cells in the urine) secondary to an uncontrolled hypothyroidism. The severely decreased T4 tells us that Red has a thyroid issue called hypothyroidism. Hypothyroidism in dogs is a clinical condition that results from a decreased amount of thyroid hormone being produced by the thyroid gland. It is usually seen in medium to large breed dogs. Middle aged dogs (4-10 years of age) are most commonly affected. Clinical signs most commonly seen with this condition include lethargy, inactivity, weight gain, hair loss, dry hair coat, recurrent skin and urinary infections, and pigmentation of the skin.

TREATMENT:
Red was given an antibiotic to treat the urinary infection. She was also started on Levothyroxine, which is the drug of choice for hypothyroidism.

Red has been treated for 2 months now and her mom reports that she is doing great and acting like a puppy again! Red lost 12 pounds and is now a body condition score of 8/9 which is much improved! Red had a repeat Thyroid profile test performed and her T4 is now 3.0ug/dL ( Normal range is 1.0-4.0ug/dL). Her condition is now controlled! Her mom also reported that she was urinating normally.
We are so pleased that Red is back to her old self now and that her thyroid problem is being treated appropriately.
