Small batch · Made in New York
One tin is a single ingredient. The other is the list you would use in your own kitchen. Neither needs a glossary.

Sliced and dried slowly until it turns brittle enough to snap between two fingers. Time replaces chemistry, which is the expensive way to do it and the only way we were interested in.

Small batch chocolate chip cookies, baked crisp at the edge and chewy in the middle. Nothing in here would look out of place in a home kitchen.
Everything below makes a treat cheaper, softer, or longer-lived on a shelf. None of it makes it better.
Keeps treats bendy on a long shelf. We would rather they snapped.
Nothing in a dog treat needs to be a colour a dog cannot see.
Chicken already smells like chicken when you dry it properly.
They exist to stretch the ingredient that costs the most. That is the one we are selling.
Small runs and a sealed tin do the same job without a chemistry set.
Toxic to dogs, and it appears in more human snacks than people expect. Never in either tin.
Treats are a supplement to a complete diet, not a replacement for one. If your dog has an allergy, is on a restricted diet, or is recovering from illness, check the tin with your vet first.
