Dogs, like humans, can suffer from kidney infections. It is important to know the symptoms of kidney problems and take the dog to the veterinarian as soon as you recognize it. If left untreated, kidney infection or other kidney problems can lead to kidney failure, or even death.
Symptoms of kidney infections may not appear in dogs initially, as bacteria take time to grow and affect organ function. When symptoms appear, the infection may already be advanced and require additional care.
Kidney stones may also show similar symptoms that don’t appear at first, but they get worse over time. Stones may also cause infection.
Here are some of the symptoms you might see with dogs with kidney infection:
- Foul-smelling urine
- Pain in the side or abdomen
- Hunching over
- Lethargy or depression
- Poor appetite
- Weight loss
- Excessive urination or difficulty urinating
- Excessive thirst
- Blood in urine or discolored urine
If the condition progresses sufficiently, the dog may suffer from sepsis or kidney failure, which can be fatal. This is why it is so important to see a veterinarian at the first sign of infection.
Kidney failure symptoms include all of the above symptoms and may also include:
- Mouth ulcers
- Diarrhea or constipation
- Bad breath
Causes of kidney problems
Dogs can have kidney problems due to a number of different causes including bacterial infections, toxic substances, obstruction of the urinary tract, and low oxygen in the kidneys. In many cases, kidney problems can be caused by aging.
When it comes to infection, dogs can experience infection from bacteria either from the bladder or urinary tract, due to infectious diseases such as leptospirosis or internal parasites. These can make your dog very sick, or even kill him.
Symptoms of kidney infection
Signs of kidney infection can include an increase in drinking water, an increase in the need to urinate, blood in the urine, vomiting, weight loss, decreased appetite, decreased bending, lethargy, decreased urination, mouth ulcers, urine discoloration, difficulty urinating, fever and bad urine Odor. Since many symptoms may appear in other diseases, it is important for your vet to determine what is wrong with your dog if he shows any of these signs.
Bacterial infections caused by a bladder infection are called bacterial cystitis. Your veterinarian will need a urine sample to diagnose if your dog has bacterial cystitis. Depending on how difficult the infection is, the vet may prescribe antibiotics for two weeks or more. Your dog’s urine may need to be checked several times to determine if the antibiotics have healed the infection or if the infection recurs. Bacterial infection may be a sign of another underlying problem, such as tumors, cysts, or urinary tract stones.
Another type of infection that your dog may have is a kidney infection or pyelonephritis. This infection is the same infection as bacterial cystitis, only the infection reached the kidneys. This infection often appears in very small dogs due to birth defects, in very old dogs and those dogs that have damaged the immune system. Although this type of kidney infection can show the same symptoms of bacterial cystitis, dogs that have been suffering from this disease for a long time will show small symptoms until the kidneys fail.
Your veterinarian may put your dog on antibiotics for one to two months. If your dog is really sick, he may be hospitalized and given IV fluids in addition to injecting antibiotics. In extreme cases, the affected kidney is removed.
Infectious diseases, most notably leptospirosis, can cause inflammation of the dog’s kidneys. The condition is called interstitial nephritis. Leptospirosis can be infected by drinking contaminated water or by coming into contact with bacteria by scraping the skin. Leptospirosis carriers include mice, raccoons, skunk, pigs, smiles, and livestock. Symptoms include fever, vomiting, muscle aches, bloody urine, lethargy, fever, and lack of appetite. Because leptospirosis attacks the kidneys and liver, the dog may experience jaundice.
Your veterinarian will need to treat your dog with antibiotics in addition to treating the symptoms that arise from the disease. People can get leptospirosis from their pets, although this is rare. However, if your dog suffers from a kidney infection due to leptospirosis, it is important for you to contact your doctor.
Another type of kidney infection a dog may have is caused by internal parasites. Kidney worms may infect your dog: Capillaria plica and Dioctophyma renale, also called giant kidney worms. Both of these worms are uncommon in pet dogs. Dogs can get Capillaria plica from eating earthworms. Giant kidney worms can infect your dog by consuming earthworms, infected frogs, or infected raw fish. While Capillaria plica exhibits few symptoms, a giant kidney worm often causes abdominal pain, pain around the kidneys, bloody urine, frequent urination, and weight loss. It can develop into kidney failure.
Capillaria plica can usually be treated by a veterinarian with worms. If it has a bulky kidney worm, your dog may need surgery to remove the affected kidney.
