Topper had diarrhea off and on for several weeks and finally some bloody stools last year. The vet couldn't find anything and the stool specimen seemed OK when they looked under the microscope. As we were leaving, the vet tech ran out, she found hookworms in his stool. We treated him for that and he was good as new in about 3 days.
Hopefully your boy will feel better soon!
IPSID is common in basenjis. It is usually diagnosed by elimination, so all other causes need to be eliminated first, but it is something to be aware of.

The yellow can also be indicative of EPI, especially if it is soft and cow-patty like. This is also something to ask your vet about.

Hope some of this helps.

I don't think it's Idiosyncratic Diarrhea, he has had it for close to two weeks total now, but I will still mention it. Thanks.
So far I have noted down IPSIS, EPI, Gardia, and hook worms.
EDIT:
Just came back from the vet. I feel confident. She told me they were gonna take some xrays to make sure everything was ok inside. I also took a stool sample with me. Sounds like they had all bases covered.
Naturally I forgot the note with all your suggestions, but they are gonna call me later and I will ask what tests were run, and if the mentioned where tested as well.
Hmmm…diarrhea started roughly the same time as your humping post. Wonder if they're connected?
Haha, oh lord I hope not! Anyways, he was "safe"…no red lipstick out of the holster as he was doing that. 
Besides, he was doing it wrong anyways...lol
Hmmm, do then make chastity belts for male dogs? 
Actually, they do…most ppl just put britches on the girls, though.
Well, just got off the phone with the vet. Everything seems fine. Xrays etc showed nothing out of the ordinary inside him. She also looking inside his colon with a camera, and they took a blood test (which we will have to wait for results).
What she did know, was he had high amounts of white blood-cells, which could be a result of stress (his separation anxiety came to mind), as well as an infection of some sort. We will be treating him with antibiotics until the blood tests come in, and he is to go back to his kibble. She informed me all "Basenji" type infections will be tested, as well as the "usual suspects".
Gizmo was apparently playful, and for one unsupervised moment, he managed to get a hold of his leash and eat a chunk of it! What a guy!
So I can pick him up in one hour.
I am so glad to hear that he is Ok..it could be stress related..expecially since he is going through separation anxiety..
Hopefully he is back to his normal self soon…
The only thing I have been doing differently was moving his bed out of my room and into the living-room. But he is positioned so he can see me.
Hm, I think I will move him back in. At least until his poop is solid again (hopefully).
Gonna also buy a D.A.P. collar and see if that helps.
Some of the experts here feed their dogs pumpkin or sweet potatoes to firm up the poop. After you get him back on an even keel, check the nutrients in the food you have been feeding him…make sure it is appropriate for his breed, development stage and size. There are lots of great suggestions in Feeding and Nutrition.
He may have reacted to getting snarked at by that Boxer, too. It doesn't take much to set a Basenji off.
Our Dalmatians got this a few times and we would get them on Flagyl (metronidazole) which seemed to do the trick in a few days. It is probably listed under a different brand name in Norway. You may want to ask your vet if they think this drug may help.
Agree with all said above - when Gemma has that problem, too often it seems to me, the chicken, rice and cottage cheese diet seems to clear it up. She's never had the blood situation though, so have the vet check for Giardia, and follow her suggestions - best of luck to you - poor baby.
So happy to hear your boy is comming home and doing well. Has to get better so he can go find another kitty again. I do know Jaycee does not like change we took the sofa out and it upset her bottom end that night better next day. Then fourth day we got new sofa and upset her that day again and now all is well. I would try putting his crate back in your room. Take care.
