My dog has allergies, and has been on allergy shots and prednisone at times to help. Since moving, he hasn't needed shots, but his itching was pretty bad today so we agreed to give him prednisone we still had from before the move. Dh incorrectly recalled the dosage and gave him 3times what we normally give. The dog got 15 mg at one time. He normally got 5. He is acting fine but I'm worried. I find all different info online for max dosages for a dog his size (20ish pounds). Watch and wait, or find a 24 hour emergency vet clinic?
Re: Vet/dog question from a lurker
I've given really high steroid loads before, in extreme cases (a last ditch effort to save a puppy when in a county without vet care). He didn't live long enough to taper, but it was unrelated to the steroids.
I'd mostly want to know about tapering and what I should look for that would hint he was struggling. I don't think I'd be concerned enough to bring him in at this point unless something scary starts happening or the vet freaks.
For future reference, if you realize a med error quickly, force feeding (with a syringe) large amounts of hydrogen peroxide can make a dog vomit.
It looks like a short term high dose isn't a big deal according to this site:

But this one says it can be fatal, with no details about WHAT a fatal overdose level is: https://www.buzzle.com/articles/prednisone-side-effects-in-dogs.html
I'd call your vet and be prepared for some side effects, even if pup doesn't usually get them.
Even if it doesn't make him less itchy, it's just better to have him on a better quality food. Purina is kind of like us eating fast food for every meal. It's food, but not good food.
