We suggest introducing your pet to our supplements as early as 3 months of age.  Starting early may help in preventing future health and wellness issues. You've heard this Benjamin Franklin quote: "An ounce of prevention is worth a pound of cure." We wholeheartedly believe in prevention. Keep in mind that with healthy, active young pets, you may not notice an obvious effect, but you can rest easier knowing that you've improved their overall health.  Our products are especially effective for adult and senior pets (ages 3+). Those that are experiencing health difficulties may see more significant and timely benefits than those that are still strong and healthy.
