If the dog's uterus and external genitalia are infected with bacteria, purulent discharge will occur. At this time, the secretions need to be collected for culture, and inflammatory factors need to be checked for blood routine. If the inflammatory response is high, it needs to be combined with B-ultrasound examination to determine whether it is a reproductive system disease such as pyometra.

The above symptoms will also occur if it is a urinary tract infection, so it is necessary to combine blood biochemistry to determine kidney function. It is recommended that the owner take the dog to the hospital for treatment as soon as possible. It is best to prepare an Elizabethan ring for the dog to wear. Because of a urinary tract infection, the dog will feel very uncomfortable and will keep licking, which may lead to more bacterial infections and aggravate the condition.
