A couple of years ago, our dog Hayley, who is about 10 years old went for a regular vet visit. Because she sleeps often and had gained some weight, the vet tested her for thyroid disease. It came back negative but her symptoms warranted a check. I was relieved to know it was negative.
As the mother of a daughter who diagnosed with Hashimoto’s Disease at age nine, we are very familiar with thyroid disease and the havoc it can wreak on a body. Yet, even though we were knowledgeable about the disease, I admit I hadn’t known how prevalent it was in both cats and dogs.
As in humans, the thyroid is the largest endocrine organ in the body and it affects the function of every organ in the body.
