I'd go and find yourself a decent dressage trainer too. You can't learn dressage from the internet/a book!! You can get advice, but you need someone there with you on the ground to point out where you're going wrong.
We trotted Phoebe up yesterday and there was no sign of lameness in her at all so I took her for a walking trek and she was really good and did a wee trot in the paddock when we got back. I rode her again today and took her in the far field and I am going to start working on the dressage scale and was counting out her strides in each gait while we ran through and easy low level dressage test. Well she has a good rhythm in her walk and trot but just needs some work in her canter. So I am going to work on her canter and transitions before we move up in the scale.
So my question for today is how can I get a better rhythm going in her canter?
Whooooooooooooaaaaaaa there hun.
You need to condition the horse first! How long has she been off??
If it's been for more than 4 weeks, I wouldn't be even thinking of cantering right now. If it's been more than 2-3 months I would only be walking for a while.
And in any situation with a horse that's been off, you need to start your conditioning on a good, flat and fairly soft surface (aka an arena) to avoid undue strain.
Talk to your vet about a good conditioning program to put your horse on.
