\n New Formula is great!\n
\n \n\n \n
\n Apparently for some people the new formula was not a good fit but for us it was wonderful! No more digestive issues for our dog who had been struggling with it for all her life (even with the old z/d formula). My suggestion to Science Hills is keep both formulas. We would be devastated if you switched back to the previous one but I feel for the costumers affected by the change because I know how hard it is to have a dog suffering with diarrhea and other issues on a daily basis. Please, Science Hills: take into consideration the costumers who are happy with the new formula. We definitely approve!! Kudos\n

\n Game changer\n
\n \n\n \n
\n This new improved formula with Activebiome+ was a game changer for our nervous dog (9 year old bichon/cavalier mix) with lots of digestive issues and common diarrhea and occasional vomiting. We are so happy this is working so well.\n

\n Horrible!!\n
\n \n\n \n
\n Bring back the original option!! It’s an RX dog food for a reason!! Our pets were doing good on the original version then you go change it without warning to this horrible product. Don’t you understand our dogs are sick and take this product for a reason, do you understand how hard it is for us to see our animals suffer? Why would I want to feed my dog chicken flavor when they are allergic to chicken??!! So he relapse and get sick again? Do you even care about us and our pets? Bring back the original formula. I reported this to consumer affairs etc as well\nYou charge enough for the product, I am sure you make more than enough to manufacture both options!\n

\n Beware of New Formula\n
\n \n\n \n
\n Beware of new formula. It helped my dog with food sensitivity for two years. Recently she has become ill will uncontrollable diarrhea. I took her to a specialist who told me the formula had changed. It now contains ground pecan shells. I don’t know how any dog with food sensitivity could possibly tolerate it.\n

\n Dog will not eat the new formula\n
\n \n\n \n
\n I am extremely disappointed with Hills. My dog was doing well for a couple years on this food, until they decided to change the formula. I had zero notice about this and was left scrambling. She absolutely will not eat the new food, won’t even go near it. I don’t blame her, it looks and smells totally different, and not in a good way. My dog is very sensitive to any food changes and is also very, very picky. I’ve tried countless new foods. Finally settled on a raw diet. It’s upsetting that people are counting on this food for their dogs and just like that, a recipe change. Please don’t respond that notice was given because that did not help me. Hills, do better for your customers.\n

\n Beware: Changed formula, dog now allergic to it\n
\n \n\n \n
\n Alas, company changed formula to add their new probiotic or something to it. No warning to customers. This dogfood is expensive and requires a prescription. Some notification would have been warranted. I’m sure Hill’s sends out marketing communications. I’m not sure if they inform customers of formula changes in them. My dog can’t eat pecan shells and cranberries. Perhaps a competitor will offer a better formula.\n

\n Now with Pecan Shells, Beets, and Cranberries?! WHY?!\n
\n \n\n \n
\n INGREDIENTS CHANGED!! WHY?! Now with Pecan SHELLS, dried BEETS, and pressed CRANBERRIES - This Rx food for Rx and expensive because dogs, like mine, can only handle the hydrolyzed protein due to numerous food allergies. Putting several new food items (and nut SHELLS if you can even call that food...that's CHEAP FILLER!) that may now be triggering his numerous food allergies...so frustrating! My dog has been on this food for years (he's 9 now) after years of failed food trials and allergy testing -- He can NOT have anything with rice, peas, potatoes (sweet or white), corn, wheat, etc. along with a long list meats! Unfortunately, at this price point it doesn't make sense to keep pay this much when filled with literal garbage now. Time to start looking for a different dog food again...\n
