May affect thyroid function
When the term "may affect thyroid function" appears in a dog's diet, it means that certain ingredients in the food may have an effect on the functioning of your dog's thyroid gland. The thyroid gland is an important organ that produces hormones that play a key role in regulating your dog's metabolism and many other bodily functions.
Some nutrients and ingredients can have a positive effect on thyroid function, especially if your dog suffers from certain thyroid conditions, such as hypothyroidism, a common condition in dogs where the thyroid gland does not produce enough hormones.
On the other hand, certain ingredients can also be detrimental, especially if they are present in high quantities. For example, some raw materials or additives, if ingested in excess, can hinder the absorption of iodine, a mineral that is essential for the function of the thyroid gland.
It is important to choose your dog's food and diet carefully, especially if they are known to have thyroid problems.
