Well, final update. EM and PCR tests have not revealed a causative agent. All the pathology testing I've had done have not revealed a causative agent. Blood tests did not reveal a causative agent. Absolutely nothing has been revealed as the cause for this situation.
Only things we have revealed, is that it is
not IBD,
not Crypto,
not aerobic nor is it anaerobic, or anything else contagious. And it's NOT getting better either. If it was an injury, it should have improved by now, but my vet doubted it was an injury from the get go.
Best guess from the 5 different vets and pathologists involved, is that it is something congenital, and they think it would have presented itself eventually, and that perhaps the breeding caused it to present itself sooner.
I guess I should be happy that it's not a contagion. But I'm having a difficult time being happy about it. I almost wish it was, so I could have a solid answer.
So, after all is said and done, I will be donating him for medicine. They can spend their own money watching him, and testing, to
maybe come up with an answer down the road, as it progresses, or as new tests are developed.
