Older Shepherd Mix Eats Iams ProActive Health Active Maturity

We have a Shepherd/Labrador mix. Her name is Shelby and she's over 16 years old now. We usually give her Iams ProActive Health Active Maturity, a dry food. Once a day we give her half a can of Alpo. We supplement her food with Iams Veterinary Formulas Joint Formula when she sometimes has some problems with her back legs.
We use those brands because they're good food. Our vet approves of them.

We usually get the food at the local Petsmart because it's conveniently close. Older dogs need good food and healthy vitamin supplements. Watch your older dog, pay attention and don't let them suffer if they're in pain.
