Questions & Answers

10 Customer Questions


what % of protein is animal source?

Answer by ChewySep 07, 2022
This Recipe contains approximately 80%-85% of animal source protein.

Are the ingredients independently tested for toxins, including mercury, anesthetics found in animal tissue or pathogenic bacteria and other substances?

Answer by ChewyAug 24, 2021
Health Extension has a 3 Step Check Point System. All ingredients are tested prior to arriving at their plant to ensure quality and safety. This includes things like toxins, heavy metals, pathogens etc. No ingredient that does not pass these series of strategic tests is permitted into the facility. The ingredients then go through an additional series of testing after being placed in a holding container immediately before being used in the recipe itself. Lastly, the final product goes through a series of additional testing to confirm the quality of the finished product.

There is no mention of GMO status of the ingredients. Are they used?

Answer by ChewyAug 19, 2021
Health Extension recipes are prepared without any artificial colors, flavors, or preservatives, and are 100% GMO ingredient free.

Does the grain free health extension foods contain taurine?

Answer by ChewyJan 14, 2020
Taurine is naturally occurring within meat so it is not added synthetically in the ingredient listing.

Good smell

My tweeny dachshund loves this variety. I mix this one with the buffalo white fish variety and top it with their gently cooked duck and Kale wet food.

Presley loves duck and I found the duck Healthy Extension. Presley loves my dogs kibble Healthy Extension, so when I saw duck I bought it. But she is elderly and has a hard time eating the bigger pieces. So she will have to eat the chicken or Buffalo kibble.
