High blood pressure is relatively uncommon in dogs. Most dogs are diagnosed with secondary hypertension, meaning high blood pressure that has an <\/span><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC6271319\/\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">identifiable cause<\/span><\/a><span style=\"font-weight: 400;\">, such as kidney disease, adrenal gland problems, or other medical conditions.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">When a dog has high blood pressure, veterinarians usually treat the cause. To bring blood pressure back to normal, veterinarians use many of the same drugs doctors use in people, including ACE inhibitors such as <\/span><span style=\"font-weight: 400;\">benazepril<\/span><span style=\"font-weight: 400;\">, <\/span><span style=\"font-weight: 400;\">angiotensin-II receptor blockers<\/span><span style=\"font-weight: 400;\"> (ARBs), <\/span><span style=\"font-weight: 400;\">beta blockers<\/span><span style=\"font-weight: 400;\">, <\/span><span style=\"font-weight: 400;\">calcium channel blockers<\/span><span style=\"font-weight: 400;\">, and <\/span><span style=\"font-weight: 400;\">diuretics<\/span><span style=\"font-weight: 400;\">. Spironolactone is not the first drug a veterinarian will use. Instead, it\u2019s added if other drugs aren\u2019t working or there\u2019s a problem with low potassium levels.\u00a0<\/span><\/p>\n<p><b> <\/b><b>How to manage high blood pressure in dogs<\/b><\/p>\n<h3 id=\"glomerular-disease\"><span style=\"font-weight: 400;\">Glomerular disease<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Glomerular disease is a type of kidney disease. The glomeruli are groups of small tubules in the kidneys. When blood passes through these small tubules, substances the body doesn\u2019t need\u2014like water and waste\u2014pass through them into the urine. Stuff the body does need\u2014like blood cells and proteins\u2014are filtered so they don\u2019t pass out of the body. Glomerular disease describes what happens when that process doesn\u2019t work, so the urine gets foamy or discolored, and fluid builds up in the body.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Glomerular disease in dogs is always a result of medical conditions like diabetes, infection, drugs, autoimmune disorders, or other diseases. The veterinarian will primarily address these other causes. To reduce swelling and fluid buildup, veterinarians use diuretics to increase water loss. If potassium levels get low, spironolactone is added to diuretic treatment.\u00a0<\/span><\/p>\n<h2 id=\"is-spironolactone-safe-for-dogs\"><span style=\"font-weight: 400;\">Is spironolactone safe for dogs?<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Veterinarians consider spironolactone safe in dogs as either a backup or adjunct treatment. Because spironolactone prevents the kidneys from eliminating potassium, it is not safe to give to dogs with high potassium levels. Some medical conditions, such as <\/span><span style=\"font-weight: 400;\">diabetes<\/span><span style=\"font-weight: 400;\">, Addison\u2019s disease, and kidney problems, cause high potassium, so spironolactone is contraindicated in dogs with those conditions.

When a diuretic is needed, veterinarians usually turn first to <\/span><span style=\"font-weight: 400;\">thiazide diuretics<\/span><span style=\"font-weight: 400;\"> or <\/span><span style=\"font-weight: 400;\">loop diuretics<\/span><span style=\"font-weight: 400;\">. In dogs, veterinarians use spironolactone as an alternative or add-on treatment to induce urine production while keeping potassium levels normal.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Given the narrow use of spironolactone, the only alternative to spironolactone is another potassium-sparing diuretic used in dogs. That narrows the choices down to <\/span><span style=\"font-weight: 400;\">triamterene<\/span><span style=\"font-weight: 400;\">.\u00a0<\/span><\/p>\n<h2 id=\"summary\"><span style=\"font-weight: 400;\">Summary<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Veterinarians use spironolactone along with other medications for serious conditions like heart failure, ascites, and high blood pressure. It\u2019s not a first choice but instead a useful alternative if other medications don\u2019t work or other diuretics are causing low potassium. Treatment can be long-term or even lifelong. Doses must be given every day.\u00a0<\/span><\/p>\n<p><svg style=\"display:none\">\n  <g id=\"facebook\">\n    <rect width=\"32\" height=\"32\" rx=\"4\" fill=\"var(--social-bg)\"\/>\n    <path
