Kidney stones

Kidney stones are solid deposits that can form in the kidneys of dogs. They usually consist of minerals that crystallize from the urine. Kidney stones can have various causes, such as an incorrect diet, an infection or a genetic predisposition. Kidney stones can be very painful for dogs and can lead to serious complications if they are not treated.

Symptoms of kidney stones in dogs

How can you tell if your dog has kidney stones? Symptoms can vary depending on the size, location and number of stones. Some common signs are:

  • Blood in the urine
  • Frequent or difficult urination
  • Pain when urinating
  • Loss of appetite
  • vomiting
  • lethargy
  • fever

If you notice one or more of these symptoms in your dog, you should take him to the vet as soon as possible. The vet can take a urine sample and perform an ultrasound scan to confirm the diagnosis.

Treatment of kidney stones in dogs

Treatment for kidney stones in dogs depends on the type, size and location of the stones. Some stones can be dissolved with medication, others need to be surgically removed. In some cases, a special diet can also help to prevent the formation of new stones.

The medications used to dissolve kidney stones are usually acidic or alkaline, depending on the type of stones present. They are designed to change the pH of the urine to prevent crystallization. The medication must be taken over a long period of time and can have side effects.

The operation to remove kidney stones is usually performed under general anesthesia. The vet makes a small incision in the dog's abdomen and removes the stones from the kidneys or urinary tract. The operation can involve risks such as bleeding, infection or kidney damage.

The special diet for dogs with kidney stones is intended to regulate the mineral content and pH value of the urine. It usually consists of a low protein, phosphorus and calcium content and a high water content. The diet must be individually tailored to the dog and prescribed by the vet.

Prevention of kidney stones in dogs

How can you prevent your dog from getting kidney stones? There are a few measures you can take to reduce the risk:

  • Make sure your dog always has enough fresh water available.
  • Feed your dog high-quality food that does not contain unnecessary additives.
  • Have your dog examined regularly and test his urine for abnormalities.
  • Follow your vet's instructions regarding your dog's medication or diet.
