Why Dogs Love Sundays.
Try It Risk-Free.
Real Flavor, Not Artificial
Kibble is made through a process that destroys natural flavor, so manufacturers add artificial flavoring back in. Picky dogs can tell the difference. Sundays is made from real meat and whole ingredients with nothing artificial added.
The Air-Dried Texture
Sundays is gently air-dried, giving it a soft, jerky-like texture that dogs crave. Many picky eaters who reject kibble and wet food take to Sundays immediately because it doesn't feel like dog food.
No Fillers Masking the Flavor
Cheap fillers like corn, wheat, and soy can interfere with the palatability of dog food. Sundays contains no fillers — just real meat, whole grains, fruits, and vegetables.
