Hyperthyroidism is a hormonal disease often seen in older cats and is rare in dogs. Treatments for cats include a specialised prescription diet made by Hill’s Science Diet called y/d. It needs to be fed exclusively. It works by minimising the amount of iodine in the food which is required for the thyroid gland to produce thyroid hormone.
There are also tablets available for treatment that need to be given once, twice or three times a day. There is also a medication that can be rubbed into the cat’s ear twice a day that can manage hyperthyroidism. It needs to be compounded especially by a pharmacist.
Hypothyroidism is rare in cats but seen more commonly in dogs. There are hormonal tablets available to control the condition in dogs.
Hyperadrenocorticism (Cushing’s disease) is a hormonal condition sometimes seen in dogs but rarely in cats. It can be managed with tablets. Unfortunately, there are no specific diets that will help with this.
Hypoadrenocorticism (Addison’s disease) is a rare hormonal condition that is sometimes seen in dogs. Certain breeds like Nova Scotia Duck Tolling Retrievers are more predisposed to it. There are tablets and injections that can manage this condition quite well. Supplementation with salt or using a high salt diet can sometimes help this condition.
Hormonal problems caused by an excess of testosterone (eg hypersexuality or aggression) in male dogs can be treated / managed by surgical castration or by hormonal implants (Suprelorin) every 6-12 months.
Hormonal problems caused by an excess of oestrogen (aggression, prolonged signs of being on-heat) can be managed or treated by surgical desexing to remove the ovaries and uterus or managed with tablets or injections. Surgery is better because treatment with tablets can make the female dog more likely to develop a life-threatening uterine infection (pyometra) requiring immediate and costly surgery.
