Hi, unfortunately after some research on pet foods, I was totally devasted to learn that I've been feeding my dogs pet food that was not good for their health. I'ave been feeding my dogs Science Diet for quite a number of years but since learning more about what's in commerical pet food, I'm now feeding them an all natural holistic kibble and have noticed improvement in their overall health and wellbeing. Both Science Diet & Eukaneuba are considered commercial pet foods and contain ingredients that are not good for your pet. Wouldn't even consider IAMS for one sec, if you want to know why, click into the website below and you'll know. IAMS conducts animal testing and tortures animals, totally defeats their claim of being animal loving.
Anyway, I've provided links to a few websites that will give you some insight into commecial pet foods and the benefits of choosing an all natural pet food.
