Mange is a skin disease caused by several species of tiny mites, common external parasites found in companion canines. Some mange mites are normal residents of your dog’s skin and hair follicles, while others are not. All mites can cause mild to severe skin infections if they proliferate.
You'll need to take your dog to the vet immediately if your pet produces only a few drops of urine -- or none -- when he or she tries to urinate. Don't wait: being unable to urinate can quickly result in serious illness for your dog or even death.
Painful Urination in Dogs: Common Causes and Treatments
A few of the more common causes of painful urination in dogs include:
While your dog's bladder is normally a sterile place, sometimes bacteria can climb from the genital area into the bladder, leading to infection and inflammation. Symptoms of a bladder infection can include painful urination, urinating only a little bit at a time, incontinence (unable to hold urine in), bloody urine, or urinating often. Some dogs show no symptoms at all.
Treatment for simple bladder infections is usually 10-14 days of antibiotics, with symptom improvement often within the first few days. Sometimes the urine is cultured to determine which antibiotic will work best. To prevent a relapse, always be sure your dog completes the entire course of antibiotics your vet prescribed.
Bladder Crystals and Bladder Stones
Sometimes the naturally occurring minerals in your dog's urine can clump together, forming crystals or stones. Many things can cause the minerals to clump, including an infection, medication, genetics, diet, how often your dog urinates, and how much water he drinks.
Symptoms of urinary stones can vary depending on whether they're in the kidneys, ureters, bladder, or urethra, but signs may include slow and painful urination, inability to urinate, bloody urine, vomiting, fatigue, as well as abdominal or kidney pain.
