I'm going to try and include as much info as possible in this. I have an adult male guinea pig, Theo, who will be three this August. He had blood in his urine about 3ish weeks ago and I took him straight to the vet. The vet diagnosed him with a penis infection and prescribed hibiscrub (diluted) and baytril twice a day and metacam once a day to take down inflammation. He was then seen a week later and I was told to continue giving him hibiscrub once a day, baytril twice a day and no more metacam. He went back again a week later and they saw that there was still a white discharge on the area so stopped the baytril and told me to continue with the hibiscrub and put isathal cream on the infected area. The vet told me on the day when he next sees Theo, not to do anything so he can see how the treatment was working. I'd been doing this for a week and this Wednesday I went back to the vet and there was still a bit of discharge. Theo is also a nervous wee-er and kind of soaked tissue, a puppy pad and the vet table! The vet looked at a couple of their younger males and saw that they had no discharge and said that Theo might have a urine infection (due to the constant weeing) or still have a penis infection he's not too sure on what it could be. He instructed to keep applying the cream twice a day, hibiscrub twice a day and now baytril twice a day. I've also been changing his bedding daily so he's not sitting in his own urine (where as before I was changing it every 3 days). The vet said he might need to take samples from Theo and we have another appointment in 2 weeks but honestly the poor might is traumatised from going there and he hates the treatment! I guess what I'm asking here is; for an adult male is it normal to have discharge? (not sperm rods or boar glue) it's a white thick discharge and sometimes it's more than before sometimes less. I ask because the males the vet looked at were not adults. Sorry that this is so long!
