I would supplement with a hip and joint supplement anyways. Especially since you said she was or is having issues.

Here are a few companies that I’ve looked into and I’ve heard of others using.
Welly Tails
Vet’s Best
K9 Joint Strong
Mercola

And also a link to a thread I had started that has good information from Hound Dog Mom on joint supplements.

As far as a food similar to Acana I’m not sure on that.

If it was me I would just find a good dog food high in protein, low in fat (since you said she was overweight) and add the hip and joint supplement instead of trying to find a food you think might have the appropriate levels to support healthy joints along with low fat and high protein. But I am certainly no expert so perhaps others will chime in.
