Tuna Twigs are crunchy, thin one-ingredient treats made from 100% USA-sourced tuna. These are yummy cat and dog treats that are perfect to be broken up into smaller bite-size pieces. Tuna is high in omega-3 fatty acids which benefits cardiovascular health and improves skin conditions. We use human-grade, natural ingredients to make a special treat that dogs (and cats too) love! Tuna is a great protein alternative for dogs with food allergies.
