is your dog smells nice?? feels healthy?? and thinks smart?

I can't smell so I really can't answer your first question but no one's complained so far! How they smell can have as much to do with what foods you feed them as any shampoos or perfumes you put on them. I've researched dog nutrition and commercial dog foods pretty well and I personally don't like any of the brands you mentioned. There's much better foods out there than any of those. The last reply you got mentioned an excellent brand of food. Nutro Lamb and Rice is what we use. It's not the best food on the market but it's definitely much better than the majority of icky grocery store foods! And it works nicely to help combat our lab/pei's skin allergies because it doesn't contain corn products in it. I show my great dane in AKC shows so when he's being shown we're much more picky about his grooming. Usually though we just use a gentle dog shampoo about once a week or so to keep him clean. No, what food you feed them has no affect one way or the other on how smart they are. I agree, this has a lot to do with genetics and to some extent the breed of dog. Although there are quite a few breeds that I feel are mislabelled as "dumb". Afghans supposedly came out the "dumbest" in a study but this is actually not true. Afghans are sight hounds and were created to range far ahead of their handlers. They had to be smart enough to make their own decisions so their independant nature sometimes leads them to being hard headed in some ways. They're not dumb but they can generally be more difficult to train than some breeds. It's the same for many of the more stubborn, independant breeds. If intelligence is important to you try to seek out dogs that were developed specifically to work closely with their handlers. In my years of working with, training, and rehabbing rescued dogs I've found German Shepherds to be one of the most intelligent, eager to learn breeds! They're often smarter than their owners and if not given sufficient mental stimulation turn to annoying habits in an attempt to try to meet their own mental needs.

Food will not make a dog smarter. That is determined by genetics. If both the dog's parents were doofus', chances are your dog isn't going to be winning any sort of genius prize. Dog food doesn't affect the dog mentally, at least not directly. A good quality dog food will help get the dog in better physical condition, which could affect his performance mentally. My dogs are fed Innova Evo, which is a grain free food you can buy at specialty pet stores and feed stores. The food doesn't make them smarter, but their coats look nice and they are in good physical condition. Of course I pair that with lots of exercise and grooming. There is no miracle food.

Our dog is bathe at least thrice a week so that he stays smelling nice and clean.

I my dog smelt lovely ((past tense because he was sent away a few years back to join the police)) but yea he was aired daily so no bad smells and he was washed with some dog shampoo that smelt minging when applied but lovely when rinsed off. He was a very healthy dog with alot of energy, not too fat not too thin and i fed him on a supermarkets own brand food and ham because he loved his ham hehe

I don't recommend any dog food that uses recycled pets in its product. I recently found out the "mystery meat" labeled on the back of dogfood bags is quite possibly rendered animal fat obtained by euthanized pets. Disgusting. I don't want my dog to be a cannibal. It is revolting. At first I thought that this was just a hoax. Then I found the article that was in an actual Missouri paper. So what happens when a pet has artificial limbs, cancer, or other disease and gets rendered and added to the food? :( Isn't Mad Cow caused by cows canabalizing themselves?

My dog stinks he eats poo. hehe :D
