How about something simple and to the point:
Cassy and Loki’s Healthy Dog Treats

if appropriate with some they could be:
Cassy and Loki’s Grain Free Dog Treats

or, if appropriate:
Cassy and Loki’s Healthy Organic Dog Treats

Depends on which if any will be grain free or organic ingredients or in the instance of the Apple and Oats could be just Cassy and Loki’s Healthy Dog Treats
