I don't have a dog and I don't intend to ever get one, but I babysat my sister's dog for a couple of weeks before. She was going away last summer and the summer before and she didn't have anyone to watch her dogs so I decided to help her out and watch the dog for her. Well, I didn't realize what a big undertaking it was.
I had to constantly chase the dog as it was a puppy and was trying to eat everthing in sight. Anyway, I did notice the dog food. Some smell better than others. The first time that I watched her dog she was feeding him the store brand food. Yes, it does make a difference. It seemed like it didn't hold together as well as the Iams. This Iams made it easier for the dog to eat and for me to clean it up, or not. It didn't smell as harsh as the store brand product.
I also noticed that her dog since she switch to the Iams looks healthier. I told her that I swear that her dogs coat is much healthier looking and much shinier. She switched for the some of the reasons that I mentioned but also because she has heard so many good things about Iam. I even told one of the my friends about he Iams dog food and she is thinking of switching also.
