My dog loves this food

Amazing Diet

Has helped my dogs allergies, she is no longer licking everything (her tail and butt where her main go to). She doesn't let the food sit in the bowl like she did with other hydrolized diets and yes we tried a majority of them. I do have to add water to her food to get her to eat, but that was done even before I had to switch to this diet.

My itchy dog does really well on this diet and he likes it a lot! There are some other specialized diets for allergies that he just doesn’t care for and apoquel alone isn’t enough for him.

New Formula is great!

Bella

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

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.

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 You charge enough for the product, I am sure you make more than enough to manufacture both options!

Beware of New Formula

Opal

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.

Dog will not eat the new formula

Renee

3 months ago
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.

Thank you for your review. 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. With the reformulation, it now includes the addition of ActivBiome+ Multi-Benefit Bundle. An advanced blend of prebiotic fibers and antioxidants to support digestion, bolster the immune system, and support organ health. The formulation change with the added ingredients have made the appearance of the product darker. All of our products are 100% satisfaction guaranteed. If you would like to take advantage of this guarantee, please return the unused portion of the product to the place of purchase for a refund or exchange.

Questions

1 - 9 of 9 Questions

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
