Formula Change Without Warning

Tommy

2 days ago
I am beyond disappointed with Hill's Prescription Diet z/d Skin & Food Sensitivities. My dog has IBS, and this has been the only food she could tolerate for years. It literally kept her healthy and stable—until now. With the last shipment, we noticed they quietly changed the formula and flavor to chicken. No warning, no notification, nothing. After eating it, my dog immediately had a terrible reaction—loss of appetite, vomiting, lethargy, and an aggressive flare-up of her symptoms. We had to rush her to the vet. This is irresponsible and unacceptable. When you’re dealing with pets who rely on prescription food for their health, changes like this must be clearly communicated to owners and vets. Instead, I was blindsided. I’m returning the food immediately and will be looking for alternatives. Hill’s has lost my trust.

No, I do not recommend this product.

I would have given this formula 5 stars up until about July. The last bag I bought my dog started itching again & wouldn’t eat it. So, I called HILLS Rx & asked if they had changed the formula. She said they did but only slightly. Well, that slight change ruined it for my dog. I had found the perfect dog food but now they’ve changed it :(

Terrible "improvement".

My dog has lost 10% of his body weight because of IBD. Our vet had us switch him to a hydrolyzed diet. It was working well until they changed from the original formula to this new formula. My dog will not eat it at all. I don't blame him, it smells horrible. I will be going back to the vet first thing tomorrow morning to see what alternative they have to Hill's, because my dog needs to eat.

Adding Ground Pecans as a filler does nothing to ‘improve ‘ this food

Suz

11 days ago
My dog was on the ‘original’ formula for years. What a shock when my latest autoship arrive! Instead of a creamy consistency, tan color and appealing smell, it is now dark brown, grainy and smells awful. I’m sure the addition of “ground pecan shells” can be attributed to this. This has nothing to do with ‘improving’ the food. Ground pecan shells are nothing but filler and I can’t imagine having any nutritional value. I’ve sadly cancelled my autoship because my dog won’t eat it. There was no way to ‘slowly introduce the food, as my previous autoship was used before opening the first can of the new formula. I checked on the Z/D dry food and that now also has ground pecan shells in it. No thank you. I’m switching to a new brand of hydrolyzed protein canned and dry food. Thank goodness there is an option.

Thank you for taking the time to reach out to us with your concern. 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—sometimes involving a simple ingredient change, and other times, like now, introducing new innovations such as our ActiveBiome+ formulation. ActiveBiome+ is an advanced blend of prebiotic fibers and antioxidants designed to support healthy digestion, strengthen the immune system, and promote organ health. We understand your concerns about ingredients when it comes to feeding your beloved pet. While feeding pecan meat is not advisable, pecan shells do not contain the same toxic compound as the meat. The shells are considered a safe and beneficial source of fiber and received an official AAFCO definition in 2011. In a pecan cracking plant the shells go through a thorough cleaning process. The pecan shells receive 180 degree hot water washings and subsequent drying after separation from the pecan meats.

Hate this food

My girl with EPI has been on this for almost the last year and this has been something that has kept her SIBO under control. We just got a new bag with the new formula without warning and she’s refusing to eat. While her poops are good they’re only going to be good if she chooses to eat her food she’s in G.I. distress and we had no warning of this. Our Vet would have called us. Had they known we will be calling on Monday and switching away from Hell and not buying hills again unless a change can go back to the old formula she can tolerate

Sudden formula change is concerning. Going to have to find an alternative. I called my vets office and they weren’t even notified of the change!

Questions

1 - 9 of 9 Questions
Sort by: Newest Answers

How do I change my prescription dog food order from a 25lb bag to a 17.6lb bag?

  1. You can cancel your current autoship order and place a new order with the smaller bag size. 



Did they change the size of the 25lb bag? With the change of the picture, the bag seems to contain less food. I can fit it in the bin I have where I couldn't before and I also run out quicker. I have repeat delivery and have had to order much sooner. 

  1. It is possible. After our dog being on z/d for two years we had to change her diet as she got pancreatitis. Was it the z/d? Wasn't anything else since that was all she ate.



Has anybody noticed the color of the poop that sacked for a few days if it turns dark brown almost black concerned puppy owner with allergies!!!

  1. No, That has not happened with us and we have 2 dogs age 6 and 8 years old on this dog food.



Did anyone’s dog get worse before getting better? 

  1. My girlie (Ozzie) maintained a status quo, no better and no worse on the z/d. Her allergy symptoms manifest as scratching especially her ears repeated frequent ear infections, She chewed on her front paws.  I answered your question so you can get some idea of how many had decreased symptoms or more/increased symptoms.  She has changed to a different brand of food and is seeing a skin and allergy specialist.  She is showing the first signs of improvement I’ve seen.



Does this food have the S/O+ Shield component?

    Is this dog food grain free?

    1. Sorry! I originally said yes, but I believe I was incorrect.



    I have a 4 months French bulldog and I wanted to know if it’s for puppies too

    1. I'm sorry, I do not know if it is for puppies too. I would ask your vet how they feel about feeding a 4 month old dog the Hills Z/D. My very allergic bubs started eating this brand when he was around a year old. It took a while because I tried different brands and even raw before I tried Hills Z/D. Raw worked well with eliminating his constant itch and red muzzle, but he always had soft stool. Long story short, it seems like my dog is allergic to seafood - and most dog foods have omega-3 from fish oil. In the end, Hills Z/D is amazing for my dog! I believe the soft food version has had recall issues. But the dry dog food hasn't. I hope this is helpful.



    My shelters have been eating this food for years.  However, we just bought a new bag and since we started feeding it to my dogs they have been acting differently.  They leave half of the food in their bowls and don’t seem interested in eating it.  

    1. This happened with my dog, Geo - when I first opened a 25 lb bag! He was hesitant to eat it, and his bowel movements (timing and texture) changed. After a few days (to ensure it was the food), I ordered another bag (17 lb bag so as to not have to throw away a 25 lb bag), and he is back to normal!



    I am doing a food trial using this dog food to rule out food allergies. I noticed there is chicken liver in the food. How is that going to rule out chicken as an allergy? It is the same as chicken in other dog foods correct? 

    1. according to my vet, it is hydrolyzed chicken which means all of the allergens have been taken out
