My parents' dog was diagnosed with Legg-Perthes disease when she was less than a year old. My mother was absolutely devastated at first, she was worried that the little thing would end up in horrible pain, unable to walk, possibly not survive at all, that sort of thing. While the surgery isn't the nicest, involving taking away part of the femur bone and letting the muscles form a false joint, the dog made a fantastic recovery and was bounding around as usual a few months later.
One of the reasons why she recovered so well was that she was taken for canine hydrotherapy (swimming). My parents had already booked a three-week holiday in Venice starting three weeks after the surgery, and though it was a difficult decision, they went on it. This is mainly because I'd found them a lovely kennels which also does canine hydrotherapy, physio and all sorts (
Hainault Hydrotherapy Centre if anyone in the south of England is interested), after looking up Legg-Perthes and finding that hydrotherapy is fantastic rehab for after the surgery. So the doglet got three weeks of the kind of treatment she wouldn't have been able to have at home. She wasn't the first in-patient they'd had, and they were very experienced in treating a variety of medical conditions, including several dogs with Legg-Perthes.
She had her own room instead of being in a pen next to all the other dogs, so that she wouldn't be constantly jumping up to communicate with them. They were always popping in there and petting her - she is unbelievably adorable and friendly, which helps, but they are are really lovely people at that place. There was nothing for her to jump up onto, a tricky thing to manage at home where she had to be kept in a little pen directly after the surgery and absolutely hated it. They walked her twice a day with one person holding the lead and the other person walking in front of her to slow her down. (The image of two people walking in a slow and stately fashion around a mad little 5lb Yorkie still cracks me up.) They massaged her daily, and of course there was the swimming. Everyone loved her, she was happy as Larry, and she made substantial progress in those three weeks. They took her for regular hydrotherapy for a while after that as well, of course, but we reckon those three weeks really gave her the edge in her recovery. It's much easier when the dog is an in-patient, especially when it's an hour's drive to get to the place.
So I'd recommend finding a local place which does hydrotherapy and physio, in fact chatting to several if possible. Find out how experienced they are with her particular medical problems and also with treating dogs before and after hip replacement. My parents' dog did some swimming before the surgery too, it helped strengthen the muscles in that area (she'd been avoiding using the leg) and was probably a factor in why the surgery went so well. It's also worth checking whether there's a regulatory body for canine hydrotherapists, as there is in the UK. And shop around for prices, those vary enormously. I've found you a few local places through googling:
Waterworkz Paw Spa in Burnaby
The Spaw Canine Sports Medicine and Rehabilitation in Aldergrove
K9 H20 in Abbotsford
Obviously this will cost more money, I know, but it's nowhere near as expensive as the cost of the surgery, and obviously your first priority is sparing her pain. Which is easier said than done when you're broke, I realise. I suppose that if it can improve her recovery to the point that you don't need to take as much time off work, it might end up paying for itself? Would there be a possibility of her doing the in-patient thing like my parents' dog did for some of the time? That would be much cheaper than having to take time off work, and she would be getting looked after by professionals and would probably be in a safer environment, if she too likes jumping onto the furniture.
At the very least, talking to people who are used to dog rehab for this sort of condition will help you learn more about how it all works. We found that learning about it all made us feel less helpless, it's a more positive approach, and it moves you from the emotional side of it to the practical side, which we certainly found helped us deal with it psychologically.
Incidentally, the vet who first made the diagnosis didn't know a huge amount about the condition (though she tried not to let that show), and wasn't very interested in the idea of rehab. Nor was she particularly experienced in the surgery, so my mother found a surgeon who looked about fifteen and was much better, both in terms of experience and knowledge about rehab. He was all for using physio and swimming for rehab, and was thrilled with her progress.
Best of luck with all of this, and also with managing not to commit matricide over the next few weeks.
