I called the vets yesterday and our vet is off sick, so booked Jess in for next week for re-assessment. Had the physio last night, she seemed really good, she actually teaches the advanced vet physio classes in Newmarket. She said Jess is less than 1/10 lame and its only intermittent every 3rd or 4th step, which is not as bad as I feared. The only thing she found was a little tension under the saddle which worked out easily but we will need to have our saddle checked again, I'm not overly surprised, she has changed shape a lot being out of serious work for 3 months now. So I've decided to keep Jess in the corral for the rest of the week and see how she looks at the weekend then hopefully speak to our vet and see what she says next week.
