  • Good replacement for Iams Digestive Formula!

    By on

    We had been on an Iams form of this Rx diet, and I was nervous our little guy wouldn't make the switch. It took a couple days of consistent feeding, but now he's downing it like a champ, which is good because I have to try to keep weight on him. He also likes the wet food version of this. Btw, chewy.com, excellent customer service as always...you have the nicest people!! Please don't ever change!

  • Eats it like it's snack food

    By on

    I have an old girl lab who has been going to physical therapy for some time. the rehab hospital that treats her feeds EN as a snack. Sandi eats it as such. We worry she won't eat enough, so we leave a bowl of EN out at all times, so she can snack on it whenever she pleases. Been a good product for an old gal who eats unreliably at times.

  • Great Food

    By on

    I am confident this food is helping my baby Leo. Although, the price is very high. I'm in a fixed income n I gave up a lot to buy it. Because I love him n I have to take care of him. He's my roommate. I was floored we when I found out how much it was. But he needs it. I wish it was cheaper. Now I'm paying 4 x the amount to feed him every month. Sincerely. ViKing.

  • Used for an elderly lab recovering from liver failure

    By on

    My elderly lab had an acute illness and was unable to keep down anything but wet dog food. He had this while being treated by the vet for acute liver failure and kept it down. I've used it to help him put weight back on with great success. He can eat a large amount and keep it down because it's easily digestible.

  • Working for Our 11-Year Old Dog With Bowel Control Issues

    By on

    I have an 11-year old German Shepherd who was pooping in the house a few times a day. It was not a behavioral issue and I did some research on line to find a dog food that was less-rich for her. After about two days, switching to this food really helped to fix the problem, which has resulted in her being a MUCH happier dog! Prior to switching to this low-residue food, she was having accidents 1-2 times per day in the house and she was very embarrassed by it. As much as I want to give her a wide variety of tasty options, this was the right choice for her. It must be pretty delicious, because I can't open the bag without my cats trying to eat it.

    I was afraid that she wouldn't like this product after the Vet prescribed it but I was wrong. She loves it! :)

  • IAMS replacement

    By on Top 1000 Contributor

    IAMS quit making food Bailee was on for 1.5 years with no problems. Royal Canin Replacement was not tolerated so vet suggested Purina. Seems to be doing better and she at least likes the taste of it. Time will tell if intestinal issues subside.

  • Works wonders for my pup

    By on

    After 2 months of battle with the poop brigade and then my poor puppy having blood in her poop and only eating rice our vet recommended trying this food. Within a day she was back to herself. We were so glad we didn't have to keep her kenneled anymore. If your pup has gastro issues I highly recommend asking your vet about using EN Gastroenteric.

    My dog Irish Setter had problems with diarrhea and I tried medication,diet changes and nothing was working Until my Vet said try your Diet food. Once I put her on your En Gastroenteric Plan, he has had no diarrhea and he loves the food. Made us both happy campers!
