I feed 10 of my dogs Kirkland Signature dry, with homecooked (Rice, veggies, chicken or ground turkey) a couple times a week.
And then Lucy (the chihuahua) gets Innova, Chicken Soup, and a lot of homecooked and table scraps because she is extremely picky and changes her likes often...and will completely starve herself..so we rotate foods often for her.
And I have to say ICK to the person who feeds her dogs alpo and beneful. One of the best things you can do for your dogs is to give them HEALTHY, PREMIUM food. it is NOT overrated. It is SOO much better for them. We used to feed beneful, and other purina foods a few years ago and I am SOO happy we switched. The dogs coats are softer, silkier, shinier...They don't shed at all, their weight is better maintained, their stools are better, they go to the bathroom less, etc,etc.
So please, for your dogs sake, switch to a higher quality food.
