1: The appearance of a dog has nothing to do with the food it eats, including its hair, which is naturally inherited. This is called bloodline. 2. Dogs that blindly eat dog food will be puffy and look bloated, and there are many diseases, especially gastrointestinal diseases (this is my personal experience in raising dogs). There are many additives in dog food, which is definitely not good for eating for years. But if you eat something else instead of dog food, dogs often lack trace elements and other vitamins. . . My dog mainly eats raw food, supplemented by dog food twice a day, eating dog food in the morning and eating raw food at night. . . Eating raw food is not dangerous to Toxoplasma gondii, because I drive her worms every three months. I use happy brown sugar (an insect repellent for Toxoplasma gondii) first, and then feed Bayer or enterotoxin every three days. My dog began to eat raw food in five months, and now it is one year and three months old, with no deficiency of meat and no disease, and its gastrointestinal adaptability is excellent.
