THYROID CONDITIONS IN PETS

During the holiday season overindulgence in food can lead to the bathroom scales suggesting a Jenny Craig or Weight Watchers critical list patient. In pets, mild to severe swings in weight can be to a variety of reasons: overeating, under eating, lack of exercise, and metabolism issues. One common condition involves the hormones of the thyroid gland.

WHAT IS THE MOST COMMON THYROID CONDITION IN CATS? SIGNS?

Hyperthyroidism, an overactive thyroid condition due most commonly to a benign thyroid tumor. Signs include one or more of the following: weight loss, increase in thirst & urination, hyperactivity, racing heart, change in personality, vomiting, and diarrhea.image.jpeg


How is it diagnosed? At what age?

A blood test where a thyroid level T4 is measured. Typically the condition is first seen in middle-aged cats.

Do owners have more than one option for treatment?

Yes. Oral medication for life (methimazole), surgery to remove offending gland, and a one-time radioactive iodine injection that cures the patient in most cases.

Are there risks with lack of treatment?

Yes, severe weight loss, heart conditions, and death.

WHAT IS THE MOST COMMON THYROID CONDITION IN DOGS? WHAT ARE THE SIGNS?

Hypothyroidism, an under-active thyroid condition. Signs include one or more of the following: weight gain, sleeping more, dull coat, symmetrical hair loss, seeking warm places, and thickened/darkened skin.  Occasionally facial paralysis of one side of the face is noted called Bell’s Palsy.

HOW is it diagnosed? At what age?

Blood test to measure thyroid levels of T4, Ft4 by equilibrium dialysis, and occasionally thyroid stimulating hormone levels. Patients on certain medications may have falsely low thyroid levels and that must be taken into account.  Typically middle-aged dogs develop the condition, although it has been seen as early as three years of age at this practice.

Are there any breeds of dogs that seem more at risk?

Golden Retrievers and Doberman Pinchers







What is the treatment for hypothyroidism in dogs?
