I have an eleven year old Beagle that has had disc (spine) problems in past. Left dog overnite with someone and believed person "yanked" dog by collar while walking. When we picked him up he kept his head down and could not push open doors with snout without yelping in pain. We had some prednisone tabs and began treament as before.(About 1 year 6months since rear spine problem) . We are in the process of weening him off, 1/2 tab every OTHER day, and now he wakes up in the middle of the night yelping in pain and cannot use his left front leg, limps badly for about 5-10 minutes.We have to give him pain meds also to get him to sleep. Called local vet and he says to continue prednisone, but did not say what "stage". Should I start treatment as if from day one? 1/2 tab BID for 3 days, then 1/2 tab once a day for 3 days, etc? Vet is out of town now. Please help!
