Hi Catherine, I always recommend that our customers consult their primary veterinarian prior to starting any new product to ensure it doesn't interact with other medications their dogs may be taking. Please reach out to me at Shayne@ultimatepetnutrition.com if you have any other questions.

Yes, my older dog was on arthritis meds, and she did well on the Nutra Thrive. She is now off the arthritis meds, and is acting like a puppy! Additionally, I changed her diet, to home cooked chicken and vegetables, and the Nutra Thrive balances her nutrition.
