Sorry to hear about your Rott too, i have had experience of cruciates in 3 rotts, 2 had surgery, the traditional method not the advanced TPLO (i dont like that method) Both dogs healed well but it took a long time to get back to 'almost normal'.
my most recent girl, my vet suggested NOT doing any surgery at all, just very strict rest and lead walks only, building up very slowly if she is doing ok. I was a little unsure about how well this would work but completely agreed with my vet that with or without surgery my girl will develop some degree of arthritis so it seemed logical that if we could get the same result with rest and patience that putting my girl through the op could be unneccessary. Well i tried this and that was in october last year, she is now back to full fitness and free running daily.
> our vets concern is as she is transfering all her weight on the other leg and may injure this one too.
Bear in mind that if she has the op she will still do exactly that while her injured leg is healing, the key is to not allow excessive force which is why the lead walk only works well.
Having seen the way my girl has healed with no surgery at all i know i would never rush into surgery if i am ever to get another cruciate (god i hope not i have had my fair share!!!)
Obviously my girl would have been sore and painful through the healing process but again no different if they have the op, it is a painful procedure.
That is just my own experience and obviously that may not work for every case as each is different but discussing all options before you decide is very important.
The recovery for the suture method is around 3-6 months, my girl healed within this time without any invasive procedure at all, but you need to be strict and patient.
I hope whatever you decide your girl makes a full and speedy recovery :)
