Check Your Animals Regularly

The kidney is preparing all the urinary substances prior to excretion by filtering the blood. The two kidneys may not be working at “full speed,” but they protect each other. Each kidney takes turns when it comes to the filtration of blood. If the kidneys are healthy, the body can excrete the toxins from the blood via the urine.

Very young or older animals are prone to kidney disease. Young animals need to learn how to deal with conflicts. Crystals occur in the urinary tract if these conflicts are not resolved and kidney sand, kidney meal or even kidney stones form gradually and the filtration process suffers greatly. The kidneys are always involved in circulatory disorders (atherosclerosis).

Older animals show more weakness than young animals. Too much calcium can promote calcification and thus kidney problems can already occur at a young age. Acute and chronic diseases are differentiated when it comes to kidney inflammation or kidney disease. The former are rarely present as independent diseases. In general, there is an accompanying symptom of various infectious diseases, sepsis, purulent processes in the body, poisoning, metabolic disorders and vascular diseases.

Symptoms can include pain in the kidney area with limitations in walking, loss of appetite or fever. The animal urinates less, takes up little liquid, feels pain when urinating and the urine is dark. This means that crystals have been formed, which keep the epithelial cells from working properly. Chronic kidney disease is related to chemical substances in dogs and cats. Chemical additives in food in the form of preservatives overload the liver and this leads to chronic kidney disease. Too much protein in the diet overloads the kidney (but also the liver).

Animals show no obvious symptoms in case of chronic kidney disease. They lose weight over time, the fur is dry, they have flaky and itchy skin, sometimes there is vomiting, they drink more water and urinate a lot. In the final stage, the animals begin to vomit, get diarrhea and ulcers on the oral mucosa. There should always be a balance between the amount of proteins the diet contains and the water supply of the dog.

Many owners want their peace and quiet at night and give their pets a little water in the evening to avoid having to go outside. Thus, the toxins are not excreted from the body via the urine and a fatal outcome of a disease is promoted. Tumors, vascular disease, leukemia and FIP (Felline infectious peritonitis = peritonitis in cats) can also lead to chronic kidney affections. A strong increase of the kidney can be the only and most obvious finding in cats suffering from leukemia. Cats can be protected against leukemia with an annual vaccination. The treatment of kidney disease includes low-protein diet food, lots of rest and warmth. Physical stress, overheating and getting wet are contraindicated in animals which suffer from kidney disease.

Causes of kidney infection include: infection usually caused by bacteria; poor nutrition, high in protein, poisons or chemicals; constant mental stress constricts the blood vessels and restricts the kidney function greatly; shock conditions can lead to kidney failure; the infection first starts in the urethra and then rises to the kidneys; toxins and allergies – screening should be carried out regularly from the 2nd age (6-8 years) to discover this kidney damage early and to get treatment in time.

Kidney disease vaccinations in conflict periods are stressful for the kidneys of small animals. They can lead to kidney failure. Anesthetics are considered critical in elderly and adolescent animals. Anesthetics have often led to kidney failure in the second half of life of the animal. In very old animals, the anesthetics are often the cause of kidney failure. Heaped anesthesia in the first year of life burdens the kidneys greatly. Unnecessary anesthesia should be avoided. The kidney has a low excretion capacity in newborns up to the age of three months. Excretion problems may occur if some puppy food has a disproportionate share of uremic substances (proteins).


Pay maximum attention to the dry food. This often consists of processed raw materials, which are the result of production processes at high temperatures and which represent a threat and a tremendous burden on the kidneys. The related animal flours are especially dangerous, often being made of emergency slaughtered animals or carcasses. Increased kidney values are often discovered by chance, as they do not match the symptoms of kidney failure.

Therefore, pet owners should check the kidney values at regular yearly intervals. This is particularly important in animals put under anesthesia very often or which have passed the second age. Also, the kidney tissue can be stimulated to regenerate, provided you start early. It can prolong the life of your dog for years.
