Hi, thanks for all your comments.

We went to see the vet, and now booked to see a specialist in Birmingham regarding her leg.

The vet didnt seem to worried about the panting...

She's on MetaCam for the moment, just need to get to see this specialist and work out whats happening with her leg and get that sorted. Hopefully this will resolve the panting as well as i sense she's frustrated with not being out on walks and being stuck to brief lead walking
