Cairo, 8 year old staffordshire bull terrier just diagnosed

[spdd]

I'm going to jump in here and give my 2 cents worth. My dog was 65 lbs. We started him once a day at 58 mg and over a period of time there was no change ( 3 weeks) . We bumped it up to 68 mg and again no change for awhile then suddenly we had a couple of good ones. Peeing and thirst were the main issues. Then there was some weakness in his back end so the dose got reduced to 65 mg, still once a day. My dog crashed and at the time I had no idea about prednisone as the vet never mentioned it. He was literally minutes away from being euthanized and the vet said it was time.
Well "mah boy" is still here cause I brought him home and paid no attention to this vet. She also as a sidenote did NOT do the ACTH test at the proper times, again I found out later all thanks to this forum.
I have been to 5 different vets which include a teaching veterinary college and an IMS. All vets have had different comments and diagnosis. My point is that being an average size dog the dose my dog got was too much for him. Please do NOT give a large dose to your dog. Start out at the 1mg and build up if need be. I was told just last week that it can literally take months for a dog to respond to treatment. Every dog is different.
I come here now for all my advice and this is coming from someone that has no faith AT ALL in forums, until I came to this one. They know what they are talking about.
My dog is still a mystery, after now 4 months of problems and I'm no expert at all on here, however I've learned a few things, and I almost had my dog put down until I listened to what was being said to me here.
Hope this helps you in your decision about the dosage.
