Many problems can affect a dog’s urinary system. Obstruction, bladder stones or crystals in the urine, infection, cancer, trauma, or blockage of the urethra, a tube that allows urine to pass from the bladder to the outside of the body. Urinary tract infections (UTIs) are common in young animals, growing up to 27% of dogs. Almost all diseases are caused by pathogenic bacteria, although some are caused by fungi or bacteria, however rarely. Most of the lower UTIs in bacteria come from bacteria that grow in the external genitalia and urethra. Usually, bacteria travel through the bloodstream and form a urinary tract.


Many natural defense mechanisms help prevent UTIs. Complete and general elimination, as well as internal urinary features (high osmolality, antimicrobial solutions), help to create a hostile urinary tract environment. Anatomic barriers and mucosal protection prevent the adhesion of toxic bacteria to the urothelium.


However, when this protection is insufficient, pathogenic bacteria increase the availability of urothelium, which allows the transfer of inflammatory chemicals to the subepithelium and the inhibition of inflammatory cytokines.2 The result is inflammation and pain, manifested as dysuria, pollakiuria, stranguria, and/or hematuria.


The elimination of a strong body can allow for the restoration of normal stamina and urothelium integrity. 

Urinary Tract Infection in Dogs


Standard testing for UTI diagnosis is through urine. Ideally, all patients with a suspected UTI have to submit a urine sample collected for cystocentesis and tested for aerobic culture and antibiotic testing. Strategies used to determine the availability of antibiotics are disk diffusion and serial dilution antibiotic. The preferred method is serial antimicrobial dilution, which provides the minimum inhibitory concentration (MIC) of the antibiotic, and disc diffusion is considered less reliable and does not give MICs.


Efforts should be made to determine the location of the UTI within the urinary tract.3,4 Although areas may appear, UTIs may occur within one (bacterial cystitis or lower UTI), kidney (pyelonephritis), and/or prostate. (prostatitis). Local practice is not always straightforward and is best achieved by examining clinical history, presenting symptoms, physical examination findings, and laboratory results and images.

  • Bacterial Cystitis

The most common symptoms of bacterial cystitis include dysuria, hematuria, pollakiuria, and stranguria. Clients can see blood in empty samples. In some dogs with less urinary incontinence, the size of the leak can be severe if the infection is present. Urinalysis tests usually reveal bacteriuria, hematuria, and pyuria.


  • Pyelonephritis

Classic pyelonephritis causes fever, fatigue, vomiting, and abdominal pain; However, some patients may experience few or no of these symptoms. 5 Chemical analysis of blood can reveal new or worse azotemia, with glucosuria and cylindric (casts). Urinalysis usually shows UTI evidence but may show inactive stools (a few red or white blood cells) in patients with the viral and concomitant disease (pyonephrosis). Abdominal ultrasonography is less sensitive or less accurate to identify pyelonephritis; however, in some patients, it can produce enlarged hyperechoic kidneys with perirenal effusion and echogenic debris within the kidney lungs. Pyelectasia and proximal ureteral dilation are seen in patients with pyelonephritis and ureteral obstruction. Dogs with pyelonephritis are more likely than dogs with sterile nephroureteral obstruction to be febrile, leukopenic, and thrombocytopenic or have leukocytosis.


  • Prostatitis

Prostatitis should be blamed on male dogs, especially strong dogs, with stranguria.6 Prostatitis in castrated male dogs is rare; such dogs often have a history of recent castration. The signs and symptoms of prostatitis vary, depending on the severity of the illness. Severe infection is accompanied by severe and painful clinical symptoms; chronic infections are usually under infection. Clinical symptoms are related to pain, which may be manifested as back or abdominal pain, severe stiffness, or depression. Physical examination may reveal an enlarged prostate and asymmetric, painful to the test. Ultrasonography may suggest that the prostate should be enlarged, that it is very different, and that it may contain echogenic cysts.

Causes of Urinary Tract Infection.

  • Stones, crystals, or waste collection in the bladder or vein
  • Swelling of the bladder or infection
  • Uncontrolled drinking too much water or a weak bladder/hormone problem
  • Harassment
  • Cancer
  • Depression
  • Spinal deformity
  • Unusual birth
  • Prostate disease

Health Conditions Related to Urinary Tract Lower Problems

The most common urinary tract disease in dogs over the age of seven is the uncertainty associated with a weak sphincter urinary tract, allowing urine to “leak”. Bacterial infections are also common. Endocrine diseases such as adrenal and diabetes mellitus can put dogs at risk of infection with the lower urinary tract.

Breeds Prone To Urinary Tract Problems

Older dogs and females with diabetes are more prone to urinary tract problems. There are different types of stones, one with a tendency to build under a variety of conditions — some older dogs, some male or female, and some under certain conditions.


Symptoms of Urinary Tract Problem?

  • The following symptoms may indicate that your dog has a problem with his urinary tract:
  • Failure to urinate or pass urine only
  • Bloody or cloudy urine
  • Fever
  • Loss of control of the bladder, leaking urine
  • Increased value and/or frequency of urine

Urinary Tract Infection Treatment.

Because canine urine problems are so diverse and can be very natural in nature, your first step is to get immediate animal care for your pet. Depending on your dog’s diagnosis, one of the following may be recommended:


  • Antibiotics
  • Medications or supplements
  • Dietary changes
  • Increase water infiltration
  • Urinary acidifiers or alkalinizers
  • Fluid treatment involving internal or subcutaneous
  • Surgery or other procedures for removing stones from another or tumor
  • Surgery to correct birth defects
  • Treatment of an underlying condition that contributes to urinary problems (for example diabetes mellitus)

What Can Happen If The Urinary Tract Is Not Treated?

Undiagnosed urinary tract problems can lead to serious medical problems in addition to causing your animal to have discomfort. Infection of the bladder can spread to the kidneys and cause life-threatening illnesses. Stones can cause partial or complete obstruction of the urethra, preventing the dog from urinating. This medical emergency can lead to kidney failure and/or rupture of the bladder and can be fatal if the blockage is not removed immediately.
