Hello again,
Thank you to those of you who replied. She is doing much better now. We decided not to operate and are thankfully happy with how she is going. Her daily walks are now smaller and on leads only but she is happy again. Her face is one that easily read. The vet has changed her medication slightly and all seems to have turned out for the best.
We just have to nurse her a bit more these days. But that is not something to surprising considering her arthritis and age.
Thank you again for your responses & advice.
Cheers
