Welcome and thanks for asking your question. My name is***** am a licensed veterinarian. I am not set up to make a live call. But, I am happy to answer your question on this thread. First I need to ask you a few questions so that I can be well informed and give you the best advice.
1- How old is your dog?
2- How long has this been going on?
3- Is the swelling in his penis or testicles?
