Hi. Im looking for some advise from anyone that knows about this condition.

My puppy, Tilly, will be one at the end of October. Over the last few months she has had a very occational limp which lasts only minutes, it has happened maybe 4 or 5 times that i've noticed and has normally been when she's ran after a ball or jumped off the sofa. I was planning on asking the vet about it when i take her for her booster and yearly check up as I thought is was maybe just a bit of cramp or something. Then yesterday afternoon I took Tilly to my local Pets at Home and we were walking around when all of a sudden for right leg gave way and she started crying, i picked her up and felt at her leg and thought i could feel something clicking. I phoned my vet stright away, they said to take her in. After examining the one leg my vet diagnosed Luxating Patella and gave me some anti-inflamatories to give her once a day and said come back in a week. She said that the anti-inflammatories may help in the short term but surgery may need to be considered at some point. I then took Tilly home quite shocked at what i'd been told. She wasn't herself all evening and was unwilling to walk at all, when i managed to get her to she was limping badly. This morning she was a bit better but still limping on and off so i took her back to the vets first thing. It was a differant vet this time who gave her a good examination of both legs. His news was awful, that Tilly has this Luxating Patella in both back legs and it is the worst grade possible. He gave me some morphine based painkillers for her and we have an appointment to see an orthopaedic surgoen on friday this week, she is going to be sedated and have x-rays taken. Tonight she is moving around better and i think the painkillers are helping, she isn't herself at all though and i'm really worried for her.

Sorry for the long post. I just can't believe how this can have got so bad so quickly, before we went to Pets at Home she was absolutlely fine.
