For your own peace of mind and it is better safe than sorry, I would take him to the Emer vet if you can't get ahold of yours. I don't know if it is a bad sign or nothing to worry about, but neither of my males had this happen after their neuter. Hopefully others will chime in here for you if it has happened to them.
Ps, I just wanted to add, are you sure it is coming from his urine and not the site of the incision? |
