"My dog, Precious would not eat any dog treats at all. She for some reason would not touch them. She almost 14 and stuck in her ways. Her breath was not the freshest at all, so I went and bought her the regular Greenies and she had a tough time chewing them. I bought the Greenies for Seniors and she loves them. Her breath smells so fresh now and won't eat anything the Greenies for Seniors. She'd even prefer to eat those over her regular dog food. I love them & she does too."
