Thank you for reaching out to us. To remain a leader in nutritional health care for companion animals, we continuously research our products and periodically update our formulas to include the latest health benefits and scientific advancements. Over time, this product has undergone several updates. As a manufacturer, we notify retailers and veterinary clinics whenever we make changes to our pet food formulas. However, we understand that sometimes not all pet parents are made aware of these changes, and we sincerely apologize for any inconvenience this may cause. Reaching every single person who feeds our products can be challenging, but we are committed to keeping you as informed as possible.

Thank you for your feedback. We are disappointed to hear of your experience. Please know, we review all consumer comments and concerns, and we ensure that your feedback is shared with the appropriate departments. To maintain our leadership in nutritional health care for companion animals, we periodically make changes to product formulas to incorporate additional health or product design benefits. Despite the favorable benefits gained through the reformulation, our pets are creatures of habit and may need a little help to get accustomed to the change in the food. When the formula is changed, we recommend a transition from the old to the new formula over a seven day period (or longer for picky eaters).

Despite the favorable benefits gained through the reformulation, our pets are creatures of habit and may need a little help to get accustomed to the change in the food. We could not tell by your post if you had done a gradual transition or not. We generally suggest doing a 7-day transition, as this allows them time to get used to the new flavor and ingredients. This can also help ward off against any sort of tummy trouble.
