Welcome to the forum!
If you read through this entire thread, perhaps you noticed my post above...
I'll give you one caution - if the Veterinarian prescribes the drug Metacam politely refuse and request an alternative. Click on the drug name to find out why

The nearby university...is that a Veterinary school? If so, you are very fortunate. Please keep us updated.
