DeeLynn...the post it from 2009...I don't think you will get an answer to your question from the person who started the thread. However, tongue issues can be due to MBD, nutrient imbalances, infection, injury, dehydration, etc.
If you fill in the questions in the thread "how to ask for help" in the health section we might be able to help you figure out if its MBD or dehydration. If its tongue was injured or if its infection then you may need to take it to a vet.
Rune...your information will not correct MBD...things have to be brought back into balance and then a "normal" supplement schedule should keep it there.
