Silver Lining K9 Foundation for Dogs 90 Tabs

#10 Foundation is recommended for all dogs to support normal health and vitality. #10 Foundation is the base upon which all Silver Lining canine formulas are built. In other words, always use #10 Foundation, and if your dog needs help with specific issues, add the other formulas as required.

The exception to this rule is #20 Keep Cool which will be most effective when used alone.
