He’s bleeding from private area not when he uses bathroom but when he gets excited
Noticing bleeding from your dog's private area, especially when he gets excited, can indeed be quite concerning. There are several potential causes for this, such as physical wounds, urinary tract infections, blood-clotting issues, stones in the urinary tract, or problems with the prostate gland. Since this has been happening for five days, it's crucial to address it without delay.
In the meantime, you can gently clean the area with sterile gauze to manage any visible bleeding. However, this situation definitely requires a professional evaluation to determine the exact cause and appropriate treatment. I strongly recommend making an appointment with your veterinarian as soon as possible to get a proper diagnosis and care plan.
If you have any further questions, please feel free to ask. Thank you.
