Skip the senior food. A lot of them have reduced amounts of protein and that is the opposite of what a senior needs. Keep her on a good quality food with good quality proteins in it and you might want to add some fish oil, as well as the joint supplement. Don’t bother with a food that advertises that it has a joint supplement in it, they don’t actually have a therapeutic dose, so it would do little good. There are a few people here with senior dogs that will chime in with what else you can do to help your old gal.
