Causes

• Drinking or eating from an unclean food or water supply can expose your dog to bacteria such as E. coli. These bacteria can overwhelm your dog's immune system and lead to infection in the urethra.
  
  

Symptoms

• Your dog may urinate frequently and begin having accidents in the house. Blood in the urine is also a sign of infection.
  
  

Prevention

• Make sure your dog has a balanced diet, drinks plenty of water and goes outside to urinate every few hours. Adding a splash of cranberry juice to its water bowl will help your dog's immune system fight off bacteria.
  
  

Solution

• If your dog succumbs to a urethra infection, take it to a veterinarian for antibiotics and any additional treatments the veterinarian deems necessary.
  
  

Warning

• If untreated, a urethra infection can lead to kidney disease and become life-threatening.
