Believe it or not, your pet can have high blood pressure too! That being said, the significance of this is a bit different than it would be for you and me. Hypertension in cats and dogs is almost always secondary, which means it is caused by an underlying condition or disease. Because secondary hypertension is a signal that something else is wrong, blood pressure screening is a great way to discover other health issues in your pet such as acute kidney disease or hyperthyroidism. BP screening can help to prevent serious organ damage if a condition or disease is caught in its early stages.
