There are many reasons for blood in the urine of dogs. If you find blood in your dog's urine, the pet owner needs to observe and analyze carefully, find out the cause, and then treat the symptoms in time to help the dog return to normal.

The following reasons generally occur:

1. The most obvious symptom of dogs is blood in the urine, but because most of the dogs urinate outside, we often fail to detect blood in the dog’s urine in time.

2. Like male dogs, there may be swelling of the urethra, while female dogs will have symptoms of redness and swelling of the urethra.

3. Dogs always urinate, or when they urinate. It seems painful.

4. There will be light yellow liquid flowing from the place where the dog urinates, and the dog will keep licking it. It is best to wear an Elizabethan ring to prevent dogs from licking, causing further infection and aggravating the condition.
