I will also add the significant changes you will see will be amazing! Lol At the office, I just see dog after dog that has horribly greasy nasty fur, boogered out eyes, heaven forbid you can even see into their ears. It's disgusting!!! But like bckrazy says, (Delta is on raw which I guess would be like a grain free. Lol) Delta never has her teeth brushed, I clean her ears out... maybe once a month???... it's ultimately cheaper (actually super cheap for me because of my co-op) but if she was on kibble, it would be cheaper because she eats less, and she just LOOKS healthy. And everyone just raves about how SOFT she is. Honda (fed Nutro) was soft... but kind of course feeling and always would feel greasy even a couple days after a bath. And she could only have a bath about every four months because it would just dry her skin out and she would ITCH! Delta could get a bath once a week and still have sparkly fur. Nutrition is the number one thing. If your dog doesn't have good things going in, it's not going to have good things coming out. Lol
