Hi Larry A,
I’m not sure why you decided to switch from Wellness Core, but if you look at the G/A on both foods you are actually feeding about 75 kcals/cup less with the Ideal Balance. The fat is pretty comparable as there’s only 1.1% more fat in Wellness than Ideal Balance and the protein is considerably lower in Ideal Balance. Older dogs actually need more quality protein as they age since they don’t metabolize it as well. Lower protein causes muscle atrophy.
I would personally go back to the Wellness, since Senior dogs usually need less fat due to underactivity and overweight issues, but this is not true in your dogs case. Also, they often do eat less and can’t smell as well as they age so adding fresh food as Red suggested and bone broth as Bobby Dog or canned food as Dog Foodie and C4C suggested are good ideas. Adding a bit of wet food (canned, etc) to all the meals and mixing it in with some warm water. It might entice your girl to eat more and more moisture is always better for any dog eating a kibble diet.
Good Luck with her! 🙂
