Well, he's a lot better this morning. He had a nice walk - not too far - but no puffing and panting and stressing.

I confess we didn't give him the extra 10mg last night - he was totally hyper off the morning dose. We tried to speak to the vet last night but nobody phoned us back.

My mum spoke to a vet this morning who said that the prednisolone wouldn't be making him hyper - he was just feeling better - and to keep giving him 20mg a day - he said that was quite a low dose for him.

I beg to differ on all that. I know what high dose steroids do and 20mg prednisolone is equivalent to 80mg hydrocortisone and that's a massive dose.

I've not heard back from Dr Peterson yet but I realise there is a time difference so I'll keep an eye out for a reply.
