Answer
I can only advise less food or more exercise.  She is mature now, perhaps less active, and may need fewer calories.  Just do whatever you can make work.

I would cut out the rawhide and dental.  I don't trust any consumable chews.  They all get gnawed down too quickly to the point a dog could choke or have intestinal blockages from them.  There is a big lawsuit going on now over ''Greenies''.

The pet stores are full of toys that many dogs will quickly chew up into
pieces they could choke on or cause intestinal blockages.  If you are not
there to watch, stick to sturdy stuff such as Nylabones and Kongs.  Keep a
close eye on chew toys and quickly discard anything that is coming apart in
pieces.  Rawhide is especially bad because it swells after being swallowed.
These problems are the worst with, but not limited to, large, aggressive
chewers such as Labs.
