Alligator, insects, lab-cultured proteins and yeast are just a few of many sustainable meat alternatives being incorporated into pet food and treat products.

Colorado-based Bond Pet Foods hopes to release its first product, a fermented yeast protein dog bar, in early 2020.

Arbiom reported successful trials of the protein ingredient, SylPro, in canine nutrition.

Wild Earth launched its first complete-and-balanced dog diet during SuperZoo 2019, utilizing yeast as the main source of protein.
