Arthritis and the older dog

Hi everyone, been awhile I know. My dear sweet dog is suffering from arthritis, she hasnt seen the vet yet because I need to ask you all your own experiences with this breed . Aoife is nearly 9, she is enthusiastic about absolutely everything, food, moderate to a little exercise. One minute she is causing arguments with any dog and showing no sign whatsoever of age or pain. She doesnt go off lead anymore . But when we get home from a short walk she struggles with getting up after she rests. I am beside myself.
My vet I know will have a one track thought with arthritis.
I have been using Yumove which to be fair has helped as long as she has twice the normal dose( Yumove recommended). But I fear the inevitable decline.
Have any of you any thoughts, remedies, anything at all that you think might help.

Mm i have sent you a private message,atb.
