Kidney problems

(Redirected from Kidney problems)
A representation of Kidney problems

Kidney problems are a common condition in older dogs, which can lead to various symptoms such as weight loss, increased thirst, loss of appetite and tiredness. The kidneys are responsible for filtering waste products from the blood and regulating water and electrolyte balance. If kidney function declines, these waste products can accumulate in the body and lead to symptoms of intoxication.

Causes of kidney problems in dogs

There are various possible causes of kidney problems in dogs, such as

  • Congenital malformations of the kidneys or urinary tract
  • Infections of the kidneys or urinary tract
  • Kidney diseases such as glomerulonephritis or amyloidosis
  • Kidney damage caused by medication, toxins or tumors
  • Age-related wear and tear of the kidneys

The exact cause can only be determined by a veterinary examination, which may include a blood and urine sample and, if necessary, an ultrasound scan or kidney biopsy.

Treatment of kidney problems in dogs

The treatment of kidney problems in dogs depends on the severity and cause of the condition. In many cases, adjusting diet and hydration can help reduce the strain on the kidneys and alleviate symptoms. There are special diets for dogs with kidney problems that have a reduced protein, phosphorus and salt content. These foods should only be given after consultation with the vet, as they are not suitable for all dogs.

In some cases, it may also be necessary to administer medication to lower blood pressure, treat anemia or reduce nausea, for example. In severe cases, dialysis or a kidney transplant may also be considered, but these are associated with high costs and risks.

Prevention of kidney problems in dogs

To reduce the risk of kidney problems in dogs, it is important to ensure a balanced diet and adequate fluid intake. You should also visit the vet regularly to check your dog's health and identify possible signs of kidney problems at an early stage. If your dog needs to take medication, you should always discuss the dosage and side effects with your vet. Finally, you should also make sure that the dog does not have access to potentially toxic substances such as pesticides, antifreeze or chocolate.
