Still very frustrated as can't get hold on the diagnosis completely. As you remember, we sent Thor's blood to test TLI and the results came as 14.0 (normal range 15-50 apparently in dutch laboratories). I have asked the Dutch doctor who did TLI to provide his interpenetration, and the answer he wrote is very similar to a local vet's:
"many thanks for your email. Considering the TLI result from your dog EPI does not seem very likely to me. Usually the faecal color in case of EPI is most of cases gray. Good to hear that bacteriology and assessment of worms and Giardia are negative in your dog. Was food allergy/intolerance considered in your dog? If not, feeding only cooked rice and cooked chicken might be an option for 7-10 days. If Tylosin is given more than 7-10 days I would suggest to quit that. Hopefully these reflections might be of value."
I think there are several things wrong with his answer:
Why he thinks EPI is unlikely?
Why Tylosin can't be given for more than 7-10 days? I read here that some dogs are on Tylan for life.
Is faecal color in case of EPI is really mostly gray? I thought it was mostly yellow.
And is rice really good when dog has diarrhea? in my experience not, sweet potato or pumpkin is better.
I was almost ready to order Enzymes Diane and now I do not know what to do. If it's not EPI would he benefit from enzymes? I don't really have the vet here who can explain all of this as TLI is not administered in my country, so I have to rely on symptoms and experience
I feel somehow that the dog EPI is not well researched outside of US, and even in US probably sites like this one and mobilizaiton of active dog owners make a huge difference.
I am Anna, my German Shepherd Thor is 2 y.o. we live in Eastern Europe. The TLI result came back from the Netherland laboratory as 14.0 but their normal range is 15-50. I still give Creon 25000 with every meal, started Pet Factor B-12. He has diarrhea often and started Tylosin 1/4 tsp.
