My dogs, Mia on the left and Oso on the right. |
So today, I'm doing my post on hypothyroidism in dogs. About a year ago,my family noticed that my older dog, Oso, had become very quiet, less active, and had gained a lot of weight. He just seemed really depressed. At first, because my dog is on the older side, my family thought he was like that from old age. But then, one day when we took him to the veterinarian for his yearly check-up. After telling the vet about all his symptoms, she ran some test on him. When we got the results back, we found out that he had a problem with his thyroid gland, which, just like in humans, regulates metabolic rate.
Hypothyroidism occurs when the thyroid gland becomes under active and not enough hormones are produced. It can be caused by an auto-immune response, that is when the body will not recognized its own cells and will created antibodies to destroy the cells. This disease can be easily diagnosed with a blood test that checks the thyroid hormone levels in a dog.
Hypothyroidism developes in mostly medium to large dog breeds, ages four to ten years old. Some of the symptoms are lethargy, hair loss, weight gain, dry skin, bacterial skin infections, ear infections, skin discoloration, and depression.To treat this disease, the dog will be placed on a daily dose of a synthetic thyroid hormone called thyroxine, which will be taken for the rest of the dogs life. Periodic blood samples will be drawn to check the dosage and be corrected if necessary. After the treatment is started, symptoms should go away.
