Questions & Answers

What is the difference between the Ultra and LID formulas?

Answer by ChewyJan 29, 2021
The Ultra line is exclusively grain free. They have both grain-free and grain inclusive within the LID line. The Ultra has a superfood blend and a few different carbohydrate options and the LID line is typically one protein and a limited number of carbs (one or two at the most). Also the LID line has more protein choices within the line, Ultra is just chicken.

Works great! Fixed his digestive issues.

He’s been on a couple different kibbles. This one fixed his tummy issues and gives him a shiny coat.

I have used this from the beginning

I didn't know much about dog food for my previous dogs. I researched fillers, etc.. My German Shepherd is 10 and has perfect teeth and is in great shape and health

My dogs won’t touch this with a 10 foot pole. I could not for the life of me figure out why they weren’t eating, until I realized this is a completely different formula than we’ve been using for the past 3+ years. I have two, 5 year old, female pit mixes, ~55-60 pounds, and would NOT recommend for this breed

I love the natural balance ultra chicken but if I purchase in smaller bags so that I can pick them up it’s more expensive. I am unable to climb my 15 stairs an cannot

I love the natural balance ultra chicken but if I purchase in smaller bags so that I can pick them up it’s more expensive. I am unable to climb my 15 stairs an cannot so it sits at my front door at the bottom of steps

Woof that was good!

Trying to be more intentional about where I am spending my money so we made the switch to Chewy. First three orders were great!

I had high hopes...

Unfortunately my dog would not eat it. She ate some the first day but after that she acted like there was something offensive in the bowl...after several hours

Unfortunately my dog would not eat it. She ate some the first day but after that she acted like there was something offensive in the bowl...after several hours she ate around these pieces. After about 3 or 4 days I gave up. I don't think anything was wrong with the food...the ingredients look fine to me. She simply refused to eat it. I guess our dog just doesn't like change.
