I like Taste of the Wild. I feel like my dogs really like it. Also I think it is really healthy too. I do give my dog some food scraps too (avoiding poisonous foods like onions). I've read about it and I've gathered that it's sometimes good to have few other foods that aren't dry. It also helps...
I love hounds too! I have a houndxGSD mix, he is a little stubborn sometimes, but the German Shepherd is usually pretty easy to train so I think it is a pretty good mix. He looks like a hound, but his fur is thick and lush so its good for going on walks in the winter.
Here is a picture of him...
