What is hypothyroidism? It is a condition that affects especially the dog and occurs when the thyroid gland produces less thyroid hormone, therefore slowing down the metabolism’s function.


The dog will display one or several symptoms such as a decrease in activity, lethargy, searches for a heat source, obesity as well as skin problems such as haircoat loss, recurring infections and/or otitis. Furthermore, he can develop neurological deficits like generalized weakness, loss of coordination, a tilted head as well as convulsions.


In order to diagnose hypothyroidism, a blood test needs to be done to confirm low thyroid hormones levels.


The treatment involves supplementing the patient with thyroid hormones, and doing so for the rest of his life. A high quality diet should also be offered in order to attain and maintain a healthy weight. For the same reason, it is necessary to increase the dog’s level of exercise.

In the goal of insuring the adequate dose of medication, it’s important that a physical follow-up examination and a follow up examination and periodical blood work be done.
