Is there such thing as a "good" dog treat? Now before I get lectured on how that is not the right way to train, they should only eat once a day etc. I know all of that - but from time to time I just want to give my buddy a little treat. So I am looking for something that is easy to carry around, isn't to fattening, wont hurt him, and tastes good. Basically looking for the least harmful commercially available treat. Any Ideas?
