Dribbling blood from penis

  My netured dog (8 years old) had his left lobe of his liver removed almost 5 weeks ago. No complications and his recovery went good. Two weeks after the surgery he started dripping a very small amount of blood from his penis. The surgeon says it has nothing to do with surgery and to see my normal vet. My regular vet checked his penis for lumps, did a prostate exam and checked his urine. Everything came back fine. They put him on Baytril just to be sure of any infections but he's been done with it for 5 days now and still there's a small amount of blood coming from penis. Not all the time and usually after he pees. He is not licking the area and not painful. They did shave his penis for the surgery, could this have caused some trauma? Any info will be appreciated on what this could be or what test to get to rule things out! Thank you!

Hello!  I think it is important to establish here whether the blood is coming from the external skin - in which I'd expect the vets to be able to see that - or from within the penis.  If the latter, it is unlikely to be caused by the clippers.

I am curious as to what they tested the urine FOR.   When you say that everything was fine, did they not find blood in the urine or is it obvious when you see the per?  It sounds from here as though they haven't yet ruled out lumps within the urethra, ureter or the bladder, bladder stones, kidney stones or other causes of spontaneous bleeding from the kidneys, but I can't see your notes and therefore may be wrong.  Your vets may be able to see more using ultrasonography or radiography, perhaps with contrast involved - your vet will have a clearer picture than I of what options they have available to them at the present time if they want to visualise the bladder / urethra.  Clotting disorders are always worth consideration in unanticipated bleeding, although often other body-parts also show signs. Obviously you have been working closely with a vet;  what next steps have they  suggested at this time?   They may well have a plan going forwards, even if that plan is simply referral to an expert eg for imaging. It sounds to me as though you have a lot of questions for your vet, perhaps about what has already been ruled out and what should be ruled out next. Best of luck - I would love to hear how this case resolves if you feel like coming back to let us know when it is.
