We recommend Drs. Foster and Smith LifeStage Select Multivitamins and Minerals. Some pet owners think that they can use a "one size fits all" pet vitamin, but choosing a multivitamin that's lifestage-specific offers your pet the proper amounts and ratios of vitamins and minerals based on your pet's age and size. With five stages to choose from and a terrific bacon/liver flavor, these vitamins are hard to pass up. x Close
