  • New food for our senior

    By on

    Our vet informed us we needed to get senior food for our little Shih Tzu. He is almost 9 and he needs food with less protein and more vitamins. Food that is for senior dogs. I searched Chewy because I knew I would be able to find the kind I needed. We were a little worried because our little guy is so fussy when it comes to his food. After searching the senior food and being able to actually see all of the ingredients, we chose Nurto Ultra and he loves it.

  • Fast, Easy, NO MORE STORES for me!

    By on

    30-lb bag of dog food delivered to my door in two days -- For me this is the best -- I don't have to find a parking space, get a cart, ask someone to put food in the cart, stand in line, and then ask for someone to load it in my car. I am a cancer survivor, and cannot lift more than 10 lbs. I just discovered this option online, and said "what the heck." I will be buying my 30-lbs from now on thru this site.

  • Greyhound Approved by my two

    By on

    I switched from Adult Ultra to Senior using phase-in procedure. My two Greyhounds are doing well on this and just gobble it up. I add 1/2 can of meat with gravy dog food for each dog. I add one can of water divided between the two dogs bowels. I let soak for 20 minutes to soften mix and make it more digestible plus they get the most out of their food without it just passing through their system.

    I have been buying Nutro for years! When I read some off these reviews, I was hesitant to continue after they changed (and I believe upgraded) it. I am VERY happy with Nutro Ultra Senior and the great deal I get from Chewy!! I am very happy with Chewy and have recommended it to pet all my fellow pet parents.THANKS CHEWY....

  • Nutro Senior

    By on

    I rescued a older dog close to 3 yrs ago. Her hair was wirey and very dull. No matter what I fed her she still looked the same until I changed to Nutro Ultra Senior. Now her hair is soft, very shiney and even darker in color. She has even lost some weight which she really needed. My vet even noticed rhe changes.

  • Dogs love it

    By on

    Recently switched to Nutro Ultra Senior Dry Dog Food and both of my dogs love it. They both have sensitive stomachs and I was a little nervous to try a new food. They have had no problem switching foods and their stools have actually firmed up. Happy to feed them a dog food to meet the senior needs. Highly recommend Chewy--great prices and fast delivery.

    My dog haven't been eating lately (She's 14y/o) and she have not been doing anything lately and just look like a depressed teen (Nonoffense) and after we changes her food (she was sharing food with a GSD & A chihuahua ) she started eating and moving more and not as "depress"

  • Happy dog!

    By on

    My 12 year old cattle dog loves this food. As she’s has aged, she needs the extra ingredients that are in the Ultra food, and she loves the taste. Chewy is great with delivery and customer service, too.
