"Dog Food" has become less a term for what we feed our pets than a way of thinking about canine nutrition. It has become so easy to pull a can off the shelf that we don't even thing about what our pet's dietary needs are. We trust the pet food companies to make these decisions for us. Many of us simply think commercial dog foods are just heavily processed "people food," specifically made for shelf-life and economy, that they promote a healthy animal. Surprisingly enough, despite their availability around the world today, dog foods are a relatively recent invention. Though the first commercial dog food appeared in the 19th century, the use of bagged and canned foods only became popular in the United States after World War II. Before that time dogs simply ate whatever they could find in their environment (with a little help from their friends, of course). For farm dogs this meant raw meat scraps, raw milk, eggs and food found by scavenging. We feed a raw food diet to our animals and our pug no longer scratches himself or has ear infections. We also feed yogurts (watch out for the ones with sugars), cottage cheese, cheese, eggs, salmon, sardines, mackerel, chicken liver and kidney, beef liver and kidney,vegetables, and the occasional banana. I also add garlic to help prevent fleas. They are very happy dogs. Don't forget to add bones to naturally clean their teeth. Watch out for the carbs in commercial dog food. The starches and cellulose in grains and carbohydrates are useful ofr herbivores and humans. Without them we would find it hard to digest and eliinate anything we eat. With dogs it is a much different matter. Since dogs don't have the flat grinding teeth, a long digestive tract, or amylase in their salive, they have a difficult time with diets high in complex carbohydrates. Carbohydrates tend to stay in dogs digestive tract longer, which slows down the digestive process and can cause spasms and irritations in the large intestine as the dog must labor to process them. In the log term, too many carbohydrates can dramatically reduce your dog's quality of life and may result in health complications. As for the shampoo's be very careful what you use on your dog. Too many chemicals in most of them. After reading the last post of yours I would start at a vet first just to make sure everything is alright with you little one first. A would want a couple of tests run and then decide what to do after that. Do your own research on why a dog would smell and then go from there. Good luck to you and your dog.
