Potassium is an important electrolyte in dogs’ bodies because it helps control nerve impulses, brain function, muscle activity, and heart function.Hyperkalemia is the opposite of hypokalemia, a condition where blood potassium levels are too low. Both can result from improper kidney function, but while hypokalemia often happens when too much potassium is being lost through urine, hyperkalemia results from dogs not urinating and removing enough excess potassium from the body.If you see the signs, especially if your dog has kidney or urinary tract issues, consult your veterinarian for a proper diagnosis and treatment. Here’s what you should know about the symptoms, causes, and treatments for hyperkalemia in dogs.Symptoms Of Hyperkalemia In Dogs (Picture Credit: Getty Images)Symptoms of hyperkalemia in dogs can range from moderate to serious, but because potassium is so integral to many functions of the body, including the brain and heart, it’s essential to address these symptoms early before they become a major problem.Here are several symptoms of hyperkalemia in dogs:DiarrheaVomitingGastrointestinal upsetWeaknessLethargySlow heart rateDifficulty urinatingLow urine volumeCollapseParalysis of the limbs (limbs remain flexible, not rigid)Causes Of Hyperkalemia In Dogs (Picture Credit: Getty Images)There are several possible causes of hyperkalemia in dogs, most of which concern the kidneys and urinary tract. Some of these issues may be treated fairly easily, while others, such as renal failure, are more complicated and can be deadly.For that reason, it’s important for all underlying conditions to be diagnosed and treated by a vet.Here are several possible causes of hyperkalemia in dogs:Overdose of potassium supplementsFluid in the abdomen (ascites)Injury to the kidneys or urinary tractKidney stonesBladder stonesUrinary tract obstructionThrombocytosisLeukemiaAddison’s diseaseDiabetes and ketoacidosisCancerBacterial infectionOverdose of seizure medicationExposure to certain antibiotics or heart medicationsRenal failureGastrointestinal diseaseConditions that cause a reduction in urinationNote that a blood test that shows high levels of potassium may be pseudohyperkalemia, which appears due to potassium leaking from cells after dogs get their blood drawn. This is known to occur in Akitas and Shar-Peis, but it is not a cause for concern.Dogs who actually suffer from hyperkalemia usually show at least some symptoms, so if an otherwise healthy dog has high blood potassium levels, it’s likely to be psuedohyperkalemia.Treatments For Hyperkalemia In Dogs (Picture Credit: Getty Images)Treatment for hyperkalemia in dogs generally begins with intravenous fluid therapy to restore normal electrolyte levels. This will also help treat any dehydration or low blood pressure that affected dogs may also suffer from.When normal levels of potassium are restored, the underlying cause of hyperkalemia should be diagnosed and treated. Further treatment can vary widely based on the diagnosis.For example, if diabetes and ketoacidosis are the causes, insulin therapy will likely be prescribed. Stones in the urinary tract may sometimes be broken down with special diets or removed surgically.Additionally, discontinuing supplements or medications that cause hyperkalemia may correct the condition. For dogs who suffer from chronic kidney disease, a low potassium prescription diet may also be required.Vets can treat further underlying conditions as needed on an individual basis.Has your dog ever suffered from hyperkalemia?
