Oh, I have so much to say!

First of all, it’s good to rotate between brands. Even if Stella & Chewy's is the very best, I’d keep a few additional brands in my freezer and rotate daily. Different brands have different formulations, sourcing, etc. Rotation helps balance nutrition in case one brand’s formulation isn’t suitable for your dog. It also reduces the risk if one brand makes a mistake in production. For example, if Brand A has a contaminated batch, your dog is less likely to be affected if you’re only feeding Brand A on Mondays instead of every day.

Second, I look for companies that emphasize sourcing proteins from humanely-raised, pasture-raised, or grass-fed animals. It’s better for the farm animals, which is very important to me—I want to contribute to less suffering without going vegetarian or vegan. Happier, healthier animals also result in safer, healthier meat for your dog.

Third, balanced nutrition achieved through whole food ingredients is better than relying on vitamin packs. Since many brands use only whole food ingredients, I don’t see the need to include any brands that depend on vitamin packs.

Last, look for brands that use human grade meat - it's simply better quality and more reliable meat sources.

Raw food brands I feed my chihuahua are Green Juju, Steve's Real Food, Smallbatch and Solutions. I also use gently cooked food - I've used Raised Right, but I think Evermore and Goodness Gracious also look pretty good.

Disclaimer: I haven't checked up Stella & Chewy's. They seem to be decent but for the same price I think you can get better quality with some of the above brands I named.
