Dog Medical Diseases – Cystitis



First, it is infected with pathogenic microorganisms. Such as Escherichia coli, Staphylococcus, Streptococcus, Proteobacteria, etc.

Second, the spread of inflammation in neighboring organs. Such as nephritis, ureteritis, prostatitis, urethritis, especially vaginitis and endometritis in female dogs, inflammation can easily spread to the bladder and cause cystitis.

Third, mechanical damage. Such as urinary catheter injury, bladder stones, etc. can stimulate mucosal inflammation.

Diagnosis points

The typical symptom is painful frequent urination. Sick dogs urinate frequently. Or make a urination posture, but each time only a small amount of urine is discharged or continuously discharged in drops (urinary drip), and the performance is painful and uneasy. In severe cases, swelling of the bladder neck mucosa or spasmodic contraction of the bladder sphincter can cause urinary obstruction and pain and anxiety in the sick dog. moan. During microscopic examination of the urine sediment, a large number of white blood cells, pus cells, red blood cells, bladder epithelial cells and debris were seen. The urine is cloudy, occasionally containing mucus flocs, pus flocs and blood clots.

The symptoms of chronic cystitis are similar to those of acute cystitis, but the severity is milder and the course of the disease is longer.

The diagnosis can be made based on the medical history, etiology, clinical symptoms and urine sediment examination.


First, improve feeding management. Take proper rest and feed with non-irritating, nutritious and easy-to-digest feed. High-protein feeds should be appropriately restricted.

second. Flush the bladder with antiseptic or astringent. First use a urinary catheter to drain the urine in the bladder, rinse with lukewarm saline repeatedly, and then rinse with liquid medicine. For disinfection, use 0.05% potassium permanganate solution, 0.02% nitrofurazone solution, and 0.1% ravenul solution. In order to converge, 1% to 3% boric acid solution, 0.5% tannic acid solution, 1% to 2% alum solution, etc. can be used. For severe cystitis, after flushing the bladder, infuse 800,000 to 1.2 million units of penicillin (dissolved in 50 to 100 ml of distilled water) into the bladder. And systemic application of penicillin, streptomycin or other antibiotics.

Third, urinary tract disinfectants, such as furantidine, can be used appropriately, with a dosage of 4.4 mg/kg body weight·time, orally twice a day.

Fourth, pay attention to prevent microbial invasion and infection. When performing urinary catheterization, disinfection and sterility requirements should be observed. Diseases of other urinary organs should be treated in time to prevent spread.
