Older Dogs - diets help?o

[S800VXR]

Our two are getting on a little now and wondered if anyone recommends additions to their diets?
Ones a Chug mail and 8.5 and the others a Britsh bulldog bh who is 7.5yrs old. Both fit and healthy but a little slower nowadays, partly our fault as they are spoilt and don't get long walks much now.
We are using a mixture of chicken (not the water added shyte!), dry Wainrights biscuits and veg, normally broccolii.

The camera does add a few pounds as she is quite slim for a bully. Raw diet, that's interesting and not something we had considered. Any more details or do I just buy rump steak at the local butchers (telcos is shyte!) and throw it to her...?

Ok cheers. She has bones and demolishes them at a great rate of knots with her bite force although they are not fresh raw ones.
