It is recommended to give the suggested dosage based off your pet’s weight. Please refer to the Feeding Instructions tab and consult with your veterinarian for more information.

Is this supplement safe to use with the medication my pet is currently taking?

    Both my senior dogs had a major turn around for energy

    By on

    My 11 year old dogs always slept around the house and didn’t get up when I walked through the door but after 3 days of starting these vitamins they started running around like puppies and snuggling way more!

    My GSD saves this for dessert!

    By on

    With all the news about not enough Taurine in the grain free diet and the brand I use as being one of them-I got this multivitamin. My GSD picks it out of her dry food and sets it aside to have after her meal. Makes my life easier and I want her to have the best.

    Saw a difference!

    By on

    I started giving these to my dog almost 4 years ago. I just thought a good multivitamin was a good idea and decided on this one after some research. What a difference! Within a a month or two her coat and nails had drastically improved, she has more energy, and she doesn't shed nearly as much. And for a husky that is amazing.

    These multivitamins have helped our dogs so much. Our dogs like the taste of the vitamin so you don't need to disguise it in a treat, it is part of our morning routine.
