hrm.. Methinks I'll continue for a few days with half a tab daily to see if any changes appear.. will give it time to get going in his system, without a dosage high enough to leave him worse for wear. Sounds like a good compromise to me.
The whole tablet might be OK for a day as a loading dose, but half is the regular amount.
My vet has told me that it's a little like aspirin, which can be used as needed. But I find that it sometimes seems to be more effective after 2-3 days--probably because it's had time to have an impact on the inflammation.
